PowerProtect Data Manager for Network Attached Storage Overview

Topics:

PowerProtect Data Manager overview Additional procedures for system administrators Prerequisites Limitations Resolved limitations NAS protection deployment recommendations Role-based security Data-in-flight encryption Roadmap for NAS protection

PowerProtect Data Manager overview For network attached storage (NAS), PowerProtect Data Manager provides centralized backup and restore operations to protect data on the network.

PowerProtect Data Manager can protect NAS assets in two ways:

AppliancesAutomatic discovery of shares on supported Dell PowerStore, Unity, and PowerScale (Isilon) products. SharesNetwork File System (NFS) and Common Internet File System (CIFS) shares from other NAS platforms.

The E-Lab Navigator provides compatibility information about supported NAS types.

Protecting a NAS with PowerProtect Data Manager does not require Network Data Management Protocol (NDMP). However, protecting a NAS requires deploying a specialized NAS protection engine as a data mover between the NAS and PowerProtect Data Manager. Containerized NAS agents run on the protection engine to support multiple NAS protection operations.

NAS protection backs up and recovers ACLs and extended attributes for NFS and CIFS shares.

Roadmap for NAS protection provides more instructions about the necessary steps to protect NAS assets.

The REST API provides additional operations. The PowerProtect Data Manager Public REST API documentation provides more information.

About asset sources, assets, and storage

Assets are the basic units that PowerProtect Data Manager protects. Asset sources are the mechanism by which PowerProtect Data Manager manages assets and communicates with the storage system that stores backup copies of the assets.

PowerProtect Data Manager supports Dell EMC PowerProtect DD Management Center (DDMC) as the storage and programmatic interface for controlling the DD systems, and external DD systems.

For network attached storage, the asset source is of type NAS. Assets can be network shares or NAS appliances.

More generally, asset sources can also include vCenter servers, Kubernetes clusters, application hosts, and other supported types. These other asset sources support additional asset types, such as virtual machines. The PowerProtect Data Manager Administration and User Guide provides more information about supported asset sources and types.

8 PowerProtect Data Manager for Network Attached Storage Overview

Additional procedures for system administrators The PowerProtect Data Manager Administration and User Guide provides more information about procedures that require the Administrator role. The PowerProtect Data Manager system administrator typically performs these procedures, some of which have server-wide effect.

Many of these procedures are not specific to protecting NAS assets. However, some procedures in the PowerProtect Data Manager Administration and User Guide are prerequisites for, or also applicable to, NAS protection. For example:

Adding and configuring protection storage, including storage units Adding and configuring virtual networks Configuring additional objectives for protection policies, such as exclusions, extended retention, replication, and cloud tiering Managing protection policies, including adding or removing assets, and disabling a policy, configuring an SLA, and protection

rules Managing backups, such as editing retention periods and deleting backup copies Managing any running jobs

Review these procedures when required for your environment or when called out by a task in this guide. If required, coordinate with your PowerProtect Data Manager system administrator or backup and restore administrators.

Prerequisites Before you configure PowerProtect Data Manager for NAS protection, observe the following points and perform the following actions: 1. Ensure that there are sufficient vCenter resources available to deploy a NAS protection engine. Resource requirements for a

NAS protection engine provides more information. 2. Open the required ports between all components, including the NAS. The PowerProtect Data Manager Security

Configuration Guide provides more information and instructions.

For example, Windows file servers require an outbound rule to allow traffic on ports 139 and 445. Modify the firewall to open these ports.

3. NAS protection engines require time synchronization with PowerProtect Data Manager for deployment and operation. Configure an NTP server. In the time configuration options for each ESXi server, enable the NTP client and ensure that the NTP service is running.

4. Configure PowerProtect Data Manager. Configure PowerProtect Data Manager for NAS protection provides more information.

Appliance protection

The following prerequisites apply for Isilon/PowerScale appliances:

The Isilon OneFS Web Administration Guide and Isilon OneFS CLI Administration Guide provide more information and instructions, where not otherwise indicated here.

1. Enable basic authentication. Enable Isilon/PowerScale basic authentication provides instructions. 2. Create a NAS protection user in the System access zone with both of the following roles: BackupAdmin and

SystemAdmin.

The NAS protection user needs read/write Windows ACL NTFS and share permissions.

Supply the NAS protection user credentials as the management credentials when you add the NAS appliance, when you add CIFS shares to a protection policy, and when you set asset level credentials.

3. Some required paths are not shared by default. To protect CIFS shares, create a CIFS share for /ifs with the name ifs.

Provide full access for the NAS protection user. For added security, you can limit access to only the NAS protection user.

To protect NFS shares, export /ifs/.snapshot, and select the options to enable mount access to subdirectories and not map root users. Ensure that read-only permission is set to No.

Add the NAS protection engine and PowerProtect Data Manager by hostname, FQDN, or IP address as clients, root clients, and read/write clients to the NFS export.

PowerProtect Data Manager for Network Attached Storage Overview 9

4. For NFS shares, add clients to the exports for other shares, as required. Files with restricted permissions provides more information.

5. For NFS shares, change the global settings to enable NFS export services. Enable NFSv3 or NFSv4, as required. 6. For SMB shares, configure the following settings in the PowerScale UI SMB server settings area:

Table 4. Isilon/PowerScale SMB settings

Notes

1. A trial license is provided with the PowerProtect Data Manager software. Dell EMC Data Protection Suite Applications, Backup, and Enterprise customers can contact Dell EMC Licensing Support for assistance with a permanent PowerProtect Data Manager license.

2. If you specify a hostname or fully qualified domain name (FQDN) with an underscore (_), then communication happens by IP address, as provided during registration.

Configure PowerProtect Data Manager for NAS protection

Prepare the PowerProtect Data Manager server by performing the following initial system configuration tasks:

About this task

The PowerProtect Data Manager Administration and User Guide provides more information about each task. If your environment already protects other assets, you may have already completed some of these tasks.

Steps

1. Add protection storage.

2. (Optional) Configure a storage unit.

3. Configure virtual networks, if applicable.

4. Configure the PowerProtect Search Engine, if needed.

The Search Engine is required for File Level Restore (FLR).

5. Enable the virtual machine asset source and register the vCenter server where you intend to deploy the protection engine.

Resource requirements for a NAS protection engine

Note the following system requirements, which are the same as for a VM Direct Engine:

CPU 4 * 2 GHz (4 virtual sockets, 1 core for each socket).

Memory 8 GB RAM.

Disks 2 disks (59 GB and 98 GB).

Internet Protocol version

IPv4 only.

SCSI controller Maximum of 4.

NIC One vmxnet3 NIC with one port.

10 PowerProtect Data Manager for Network Attached Storage Overview

Files with restricted permissions

If you use limited-privilege credentials to back up files without permissions for groups and owners, additional action is required before you add the NAS appliance or share to PowerProtect Data Manager. For example, files with 500, 600, and 700 permissions. Complete one of the following sections, as applicable.

Without this action, appliance backups may fail and share backups may complete with an exception, where some files are skipped. The backup logs contain more information and an approximate count of skipped files, where applicable.

PowerScale (Isilon) appliance

On the NAS appliance, add the NAS protection engine and PowerProtect Data Manager by hostname, FQDN, or IP address as clients, root clients, and read/write clients to the NFS export for the share. Enable mount access to subdirectories.

The Isilon OneFS Web Administration Guide and Isilon OneFS CLI Administration Guide provide more information about clients, modifying NFS exports, and adding a client to an NFS export. The Add NAS wizard contains a reminder for this step.

NAS shares

Add the NAS protection engine by hostname, FQDN, or IP address as a client of the NAS server to ensure that the NAS agent can read these files with restricted permissions. Because NAS server platforms can vary significantly, consult the documentation for your NAS server for instructions.

Enable Isilon/PowerScale basic authentication

For Isilon/PowerScale 9.2, basic authentication is disabled by default. Before you add an Isilon/PowerScale appliance, enable basic authentication through the appliance console.

Steps

1. Connect to the Isilon/PowerScale console.

The Isilon OneFS CLI Administration Guide provides instructions.

2. Enable basic authentication:

isi_gconfig -t web-config auth_basic=true Privilege elevation with sudo may be required, depending on the user permissions and appliance configuration.

Supported Internet Protocol versions

PowerProtect Data Manager only supports the use of IPv4 addresses.

Using an IPv6 address can result in errors or other unexpected behavior. When configuring devices to connect over the network with PowerProtect Data Manager, use only IPv4 addresses.

Limitations Observe the following information when planning NAS protection:

Backup

The Appliance protection section contains related information for backups of NAS appliances.

1. NAS shares do not display a value for backup size until after the first backup completes. 2. PowerProtect Data Manager cannot back up NFS shares if the NFS export is set to map the root user to nobody. The

mounted share does not have read or write privileges, and the operation fails because of permission errors. This limitation applies to all NFS shares.

PowerProtect Data Manager for Network Attached Storage Overview 11

For Isilon/PowerScale appliances, change the NFS export settings to Do not map root users. The Isilon OneFS Web Administration Guide and Isilon OneFS CLI Administration Guide provide more information about NFS export settings and root squashing.

3. For CIFS, the presence of some special characters in the name of a file, folder, or asset name may result in the failure of backup and recovery operations. For example: <, >, and =. The Microsoft CIFS protocol documentation contains more information and a full list of special characters that should not be used.

Restricted access shares

1. For NAS appliances, the NAS agent successfully backs up discovered shares with the No Access property. The appliance permits a snapshot of the share despite access restrictions, and the agent backs up the snapshot.

To prevent backups of restricted-access shares, add the share as an exclusion. For CIFS and NFS shares, the agent honors the permission and the backups fails. All restore operations for restricted asset shares fail for both appliances and shares.

Restore and FLR

1. NAS backups do not support FLR from backups on remote (replicated) protection storage or from backups in a cloud stage (Cloud Tier).

2. When you search with FLR for folders, the folder size may be incorrectly shown as zero even when the folder contains files and other folders of nonzero size. Restore operations are unaffected.

3. The FLR UI limit is 500 selected items. Selecting 500 or more files or folders in a single FLR operation may return an error message or encounter browser limitations. To work around the limitation, restore the next higher folder, split large FLR operations into multiple smaller operations, or use the REST API instead. FLR operations to restore folders that contain more than 500 files or subfolders are unaffected.

4. For FLR, selecting both a file or folder and its parent folder from the same backup may result in inconsistent renaming of duplicate restored data. Select files and folders that do not share a parent/child relationship and select only the parent folder to recover everything in that folder. For example, instead of selecting /foo and /foo/bar, select only /foo.

5. Unity and PowerStore appliances have known mounting issues with NFS v3 and v4. Share-level recovery and FLR fail with an error when you restore to the original or alternate location under the following conditions: NFS v3: The NFS export path contains the file system name followed by a forward slash (/). For example, 10.2.3.4:/

filesystem_name/share_name.

NFS v4: The NFS export path contains a forward slash (/). For example, 10.2.3.4:/test/share.

NOTE: The NFS syntax imposes one forward slash immediately after the colon (:) as part of the separation between

host and path (host:/path). Instead, this limitation applies to any additional forward slashes that are present in the

path (filesystem_name/share_name).

Instead, restore to a location where these conditions are not present. 6. When you perform FLR on different versions of a file from multiple backups of a Linux file server, unexpected behavior

may occur. If you select the options to restore to the same folder and overwrite original files, PowerProtect Data Manager does not mark the restored files with the transaction ID. Instead, the restore operation appends the complete path to the expected restore location.

For example, the file /mnt/tmp/backup/dir4/test.txt that should be restored to /mnt/tmp/backup/mnt/tmp/ backup/dir4/test_transactionid.txt is instead restored to /mnt/tmp/backup/mnt/tmp/backup/mnt/tmp/ backup/dir4/test.txt. Other share types are not affected.

This limitation affects NFS v4 exports that were created with the option fsid=0 or fsid=root. For these exports, perform FLR to an alternate location instead of restoring to the original location.

7. For FLR and share-level restore, to restore from a backup of an asset which is no longer part of a protection policy, set asset-level credentials.

8. You can only cancel FLR operations at the job level. PowerProtect Data Manager does not support FLR cancellation for individual assets.

9. You cannot restart NAS FLR jobs. 10. For FLR, when you select Restore and Overwrite the Original Files and Folders, the operation restores the selected

files and folders to the root level of the destination. The operation leaves the original files and folders untouched. If files and folders with the same name exist at the destination, the restore operation renames the recovered files and folders.

12 PowerProtect Data Manager for Network Attached Storage Overview

The extra folder hierarchy that is created during the restore does not have the original access control lists (ACLs). Instead, the restore creates these paths with root ownership and attributes.

11. When restoring NFS shares to alternate locations, the UI prompts you for credentials even though NFS shares do not require credentials. However, the restore fails unless you provide the same credentials that were used to create the protection policy.

12. For FLR, when you restore different versions of files with Restore to an Alternate Share or Array, the resulting folder does not have the original ACLs. Instead, the restore creates this folder with root ownership and attributes.

13. For CIFS, the presence of some special characters in the name of a file, folder, or asset name may result in the failure of backup and recovery operations. For example: <, >, and =. The Microsoft CIFS protocol documentation contains more information and a full list of special characters that should not be used.

Access control lists (ACLs)

CAUTION: If PowerProtect Data Manager cannot restore the ACLs from a backup, the restore succeeds without

exception. The restore log contains more information for troubleshooting.

1. If you restore a backup to a share that uses a different protocol version from the original share, the ACLs of the restored files and folders may not exactly match the originals.

2. If a share is offered through multiple protocols, the backup only preserves the ACLs for the selected protocol. 3. When PowerProtect Data Manager cannot preserve the ACLs during a backup, that backup completes with an exception.

Backup stream counts

1. During a NAS backup, the reported active stream count may not be correct until the backup completes or until all active streams from a NAS protection engine close. During this time, the reported active stream count may not match the number of active streams as reported by PowerProtect DD. Most often, this issue occurs during full backups with large slice sizes. To determine the number of active streams before backup completion, use the PowerProtect DD UI.

Appliance protection

The following limitations apply for Isilon/PowerScale appliances:

1. If PowerProtect Data Manager was updated from an older release, the asset list may show two additional discovered entries: /ifs/.snapshot and /ifs. These assets are marked as not detected. These entries are process artifacts, not valid assets, and you can ignore them. For new installations, PowerProtect Data Manager filters these entries from the asset list.

Do not add these assets to a protection policy other than an exclusion policy. If you add them to a protection policy, PowerProtect Data Manager skips any resulting backups of these assets.

2. PowerProtect Data Manager only supports the automatic discovery and protection of shares which are part of the System access zone.

3. Share size is not automatically discovered, so protection rules which are based on share size do not return any assets.

The following limitations apply for Unity/PowerStore appliances:

1. PowerProtect Data Manager cannot back up replicated shares.

Updating from previous releases

For Isilon/PowerScale appliances with multiple NFS exports that have the same name and different properties, the PowerProtect Data Manager 19.9 UI listed the duplicate exports as separate NFS assets. These duplicate assets could be assigned to multiple protection policies. However, this behavior has changed for PowerProtect Data Manager 19.10.

If you had assigned duplicate assets to multiple protection policies, perform the following actions:

1. After updating to PowerProtect Data Manager 19.10, the UI shows one of the assets for each export in the Available state. The remaining duplicate assets for that export are shown as Not Detected. Verify whether the Available asset is part of the correct protection policy.

2. The Restore window shows duplicate assets with the same name. However, the backup data for these assets is identical. After the update, the duplicate assets remain visible. Ensure that you restore from the correct backup.

PowerProtect Data Manager for Network Attached Storage Overview 13

3. The FLR UI displays the contents of a duplicate asset multiple times. Ensure that you restore from the correct backup.

For assets that are shown as Not Detected, PowerProtect Data Manager disables the option to restore to the original location.

Capacity usage

1. For Unity/PowerStore appliances, each file system path may host multiple shares, with some portion allocated for each share. However, PowerProtect Data Manager does not show the allocation for each share. Instead, the asset size reflects the total size of the file system that contains the asset.

2. Two additional use cases can affect front-end protected capacity by terabyte (FETB) capacity usage: a. If a NAS offers shares through multiple protocols, the same data may be available through more than one asset.

PowerProtect Data Manager displays these shares for you to select a preferred protocol. b. If a NAS offers multiple shares that are part of the same file system path, the same data may be available through more

than one asset.

For example, the export paths for two shares /test1 and /test2 share the same local file system path /home/ users/validation.

If you add duplicate or overlapping assets to one or more protection policies, the FETB usage increases proportionately to the number of such assets. PowerProtect Data Manager displays a warning when you try to add duplicate or overlapping assets to protection policies.

Protection engine limitations

Observe the following points when planning and working with protection engines: Deploy protection engines with fully qualified domain names (FQDNs) or IP addresses only. Short names are no longer

supported. Existing protection engines which were deployed with short names are deprecated. A future release will require you to delete and redeploy these protection engine with FQDNs or IP addresses instead.

When you deploy protection engines with FQDNs, each FQDN must have a DNS record. Protection engines are part of server disaster recovery backups. However, the disaster-recovery process does not

automatically redeploy protection engines.

Resolved limitations Observe the following information when planning NAS protection:

1. If PowerProtect Data Manager cannot protect files, folders, or ACLs in an asset because of a permission issue, the backup skips these items and completes with an exception. This behavior is expected. However, the permission issue may happen at the root level for the asset, leaving no data for PowerProtect Data Manager to protect.

Previous releases marked this backup as completed with exception even though the backup was empty. PowerProtect Data Manager 19.10 and later releases mark these backups as failed.

2. When you remove or delete a discovered asset from an appliance, the next discovery cycle marks that asset as not detected. Previous releases marked backups of these assets as failed. PowerProtect Data Manager 19.10 and later releases skip backups of these assets.

3. PowerProtect Data Manager 19.10 and later releases support NAS protection functionality as part of server disaster recovery, enabling you to restore NAS backups in case of disaster. The PowerProtect Data Manager Administration and User Guide provides more information.

NAS protection deployment recommendations Use the sizing information presented here to calculate an optimal deployment for your environment.

PowerProtect Data Manager divides NAS assets into slices by using threshold values. The threshold slice size is 200 GB or a count of one million files, with a tolerance of up to 30%. To avoid creating nonoptimized slices, the tolerance allows PowerProtect Data Manager to deviate from the threshold value and keep data together. For example, a single 260 GB folder is still within the 30% tolerance value and would be considered one slice. Empty placeholder slices help protect the asset layout structure.

14 PowerProtect Data Manager for Network Attached Storage Overview

Each slice uses one stream. Protection engine parameters provides information about the relationship between streams and NAS protection engines. When calculating the number of NAS protection engines, allow up to 120% to 150% of the estimated slice count for overhead such as placeholder slices.

To calculate the number of NAS protection engines, divide the estimated slice count by the number of streams per NAS protection engine. For example, a 50 TB share would require 11 NAS protection engines. The calculation for this example is (50,000 GB / 200 GB) / 24 = 10.4, rounded up.

For optimum performance, use a dedicated 10 Gigabit Ethernet (10 GbE) network interface per NAS protection engine. The ESXi network stack constrains throughput. More NAS protection engines with dedicated interfaces can achieve higher net aggregated throughput when reading from the NAS and writing to protection storage.

If the entire environment is 10 GbE, including the NAS and the protection storage, network speed constrains throughput. You may find that read throughput from the NAS appliance and write throughput to protection storage are reduced in an environment with multiple NAS protection engines. In this case, increase the number of network interfaces on the NAS and the protection storage.

Asset-level parallelism balances the number of available streams across multiple assets. PowerProtect Data Manager supports multiple simultaneous backups so long as there are sufficient available compute resources. Asset-level parallelism supports up to 256 streams per asset. Set protection engine parameters provides instructions to configure parallelism.

Role-based security PowerProtect Data Manager provides predefined user roles that control access to areas of the user interface and to protected operations. Some of the functionality in this guide is reserved for particular roles and may not be accessible from every user account.

By using the predefined roles, you can limit access to PowerProtect Data Manager and to backup data by applying the principle of least privilege.

The PowerProtect Data Manager Security Configuration Guide provides more information about user roles, including the associated privileges and the tasks that each role can perform.

Data-in-flight encryption PowerProtect Data Manager provides centralized management of backup and restore encryption for application agents. Backup and restore encryption is supported for both centralized and self-service operations where applicable.

You can ensure that the backup and restore content is encrypted when read on the source system, transmitted in encrypted form, and then decrypted before it is saved on the destination storage. This prevents another party from intercepting private data.

PowerProtect Data Manager only supports encryption in-flight for Microsoft SQL Server with Application Direct, Microsoft Exchange Server, Oracle RMAN, File System, SAP HANA, and network attached storage (NAS) workloads. This is a global setting that is applicable to all supported workloads. For File System agents, restore encryption is supported for image-level restore only. For Microsoft SQL Server agents, restore encryption is supported for database-level restore only.

The PowerProtect Data Manager Administration and User Guide and PowerProtect Data Manager Security Configuration Guide provide more information about encryption in-flight, such as how to enable the feature and important considerations to understand before enabling.

About NAS protection Protection policies for NAS assets are either centralized or exclusion. PowerProtect Data Manager centrally manages all stages of the protection policy and controls policy operation.

If a NAS offers the same asset through multiple protocols, PowerProtect Data Manager provides an opportunity to select a preferred protocol for data protection.

When you add a share with ACLs and that share is offered through multiple protocols, selecting CIFS is recommended, to back up the corresponding ACLs.

PowerProtect Data Manager supports protecting NAS shares with hard links created on the same file system, so long as the hard links are for files and not directories, and do not span file systems. Soft links are not supported.

Enable the NAS asset source Enabling the asset source in PowerProtect Data Manager allows you to add and register the asset source for the protection of NAS assets.

Protection engine parameters A NAS protection engine can protect multiple NAS assets simultaneously by hosting separate containerized agents for backup and restore operations on individual shares. PowerProtect Data Manager selects a protection engine for each protection job based on engine availability.

Each protection engine has 24 parallel streams that you can use to protect NAS assets. Likewise, you can assign a number of these parallel streams to use for a particular NAS asset. By default, PowerProtect Data Manager allocates 8 streams per NAS asset, per backup operation. For restore operations, the default is 8 streams for share-level restore and one stream for FLR.

To improve performance, you can deploy more protection engines.

Set protection engine parameters

You can change the number of parallel streams to use for a particular NAS asset when you perform backup operations. Increasing the number of parallel streams may affect the performance of other operations that use the same protection engine.

Network Attached Storage Best Practices and Troubleshooting

Topics:

Review protection logs Protection engine troubleshooting Connectivity troubleshooting Snapshot troubleshooting Credential troubleshooting Backup troubleshooting

Review protection logs NAS protection creates logs at the asset and job levels that you can download to analyze when resolving problems.

Log in to the PowerProtect Data Manager user interface as a user with the Administrator, User, Backup Administrator, or Restore Administrator role.

On the Jobs > Protection Jobs page, select the job that corresponds to the problem which requires troubleshooting, and then select Export Log. The log export contains two files with consolidated logs from PowerProtect Data Manager and the NAS protection workflow, respectively. The NAS protection log contains the logs from both the NAS agent and NAS protection engine.

Review nasdm.log and Nas_sessionID.log to determine the root cause of any issue. Some of the troubleshooting guidance in this appendix uses the additional logs from the consolidated NAS protection log.

Protection engine troubleshooting The following sections provide guidance for troubleshooting protection engine issues:

Unable to reserve a protection engine

If the existing protection engines are fully reserved for backup and restore operations, reschedule some NAS protection policies for periods with lower protection engine usage.

If you have already optimized the protection policy scheduling around protection engine availability, deploy more protection engines.

Connectivity troubleshooting The following sections provide guidance for troubleshooting connectivity issues:

Before performing further troubleshooting, verify that you have an available route between PowerProtect Data Manager and the affected components. Try to ping the affected component and verify that the affected component is online.

Unable to resolve a protection engine

Connect to the PowerProtect Data Manager console and change to the root user. Using a Linux text editor, open /etc/ resolv.conf and verify that the DNS server details are correct.

Network Attached Storage Best Practices and Troubleshooting 29

Unable to connect to an appliance or file server

Verify that the network connections between PowerProtect Data Manager, the protection engines, and the appliance or file server are operational.

Error messages during protection engine or Search Engine node deployment

You may receive HTTP 503 service unavailable errors, messages about Certificate window disabled, or connection errors. Ensure that the local DNS service provides hostname and FQDN resolution for all components.

Unable to connect to a protection storage system

This symptom includes being unable to verify the connection to a protection storage system and connection timeouts.

Ensure that the stored security certificate for the protection storage system is valid. Verify that DD Boost is enabled. Verify that the protection storage system has enough available space.

Unable to add an asset source

If you can ping the asset source, connect to the PowerProtect Data Manager console as the admin user. Try to establish a connection on the applicable port with the command curl -S asset:port. Observe the output from curl.

Unable to connect to a protection engine after deployment

Verify whether PowerProtect Data Manager and the protection engine are on the same virtual network (VLAN).

Unable to back up a NAS appliance because of connectivity errors

You may receive error messages such as Unable to communicate with NAS appliance when the appliance does not respond as expected and backups may fail to start.

Verify that the NAS appliance is available. Verify connectivity between PowerProtect Data Manager, the protection engine, and the NAS appliance. Verify the appliance and management credentials and, if required, update the stored appliance credentials.

For Isilon/PowerScale appliances and protection policies with large numbers of NAS assets, the resulting quantity of REST API calls may exceed the appliance API rate limits. When this happens, the appliance API becomes temporarily unavailable. To work around this limit, move some NAS assets to different protection policies or retry the failed backups.

Snapshot troubleshooting The following sections provide guidance for troubleshooting snapshot issues:

Unable to create a snapshot

On the NAS appliance, verify whether the backup operation would exceed any of the snapshot limits. System-wide and directory snapshot limits vary by appliance. The appliance documentation provides more information.

If necessary, remove any snapshots that are no longer required and then try the backup again. Verify that the NAS appliance management credentials are correct. Check the NAS appliance licensing.

30 Network Attached Storage Best Practices and Troubleshooting

Unable to create a snapshot on Isilon/PowerScale

On the appliance, verify whether the /ifs/.snapshot directory exists. If this directory does not exist, contact Isilon/ PowerScale Customer Support.

Confirm that you have shared the required paths for CIFS and NFS protection. Prerequisites provides more information.

Unable to mount an appliance snapshot or share asset

Download the NAS protection workflow logs. Review protection logs provides instructions.

Open snapshotAndSlice.log and copy the mount command from the log. Replace the password placeholder with the appliance or share credential. Use the appliance or file server console to test the mount command.

Use the output from the mount command on the appliance or file server console to troubleshoot. Resolve configuration issues such as invalid credentials or connectivity problems. If there are no configuration issues, contact Customer Support.

Isilon/PowerScale backup times increase

An increasing number of snapshots in /ifs/.snapshot may reduce appliance performance, resulting in increased backup times. Creating snapshots for assets under the same path can also reduce appliance performance. Some task failures may also result in failure to delete a snapshot. Remove unneeded snapshots to restore performance. Manually delete Isilon/PowerScale snapshots provides instructions.

Backup cancellation or failure prevents snapshot deletion on Isilon/ PowerScale

If you cancel backups for multiple assets, circumstances may prevent removal of the corresponding snapshots from the appliance. If the backup status is Failed, retrieve and examine the log bundle. Where a system report, job status, or log indicates that the snapshot was not deleted, manually remove the snapshot. Manually delete Isilon/PowerScale snapshots provides instructions. The log bundle for the backup contains the ID for the corresponding snapshot.

Manually delete Isilon/PowerScale snapshots

Use this task as directed by troubleshooting sequences.

About this task

The Isilon OneFS CLI Administration Guide provides more information or instructions for the following steps, and best practices for creating and managing snapshots.

Steps

1. Connect to the Isilon/PowerScale console.

2. List the snapshots:

isi snapshot snapshots list 3. Determine which snapshots can be safely deleted.

4. Delete each snapshot:

isi snapshot snapshots delete --snapshot= --force where is the identifier for a snapshot which can be safely deleted.

Network Attached Storage Best Practices and Troubleshooting 31

Credential troubleshooting The following sections provide guidance for troubleshooting credential issues:

Backups fail during the mount stage with credential issues

If the snapshot mount operation fails, verify the credentials in use on the NAS appliance or share. Change the credentials in PowerProtect Data Manager at the protection policy or asset level to reflect the verified NAS credentials.

Credential issues with protection storage

PowerProtect Data Manager manages protection storage, including credentials. However, you can manually reset the storage unit password. Click Infrastructure > Storage. Select the protection storage system and then click More Actions > Manage Storage Units. Select the storage unit and then click Update Password. The PowerProtect Data Manager Administration and User Guide provides more information.

If the storage unit user account on the protection storage system is locked, you can manually enable the user account. The PowerProtect DD Security Configuration Guide provides instructions.

Unable to back up some assets on a protection policy that protects assets from more than one source

If the asset sources do not share the same credentials, verify the credentials for each asset. Set new credentials at the asset level.

Backup troubleshooting The following sections provide guidance for troubleshooting backup issues:

After you perform an asset-level restore operation, perform a full backup of the asset to maintain backup consistency.

Unable to move backups to protection storage

Verify that there is sufficient free space on the protection storage system.

Unable to discover assets

If the first discovery succeeds and later discoveries fail, verify whether the asset credentials have changed. Update the credentials in PowerProtect Data Manager accordingly.

Consecutive incremental backups fail

Perform a manual full backup of the NAS asset. The PowerProtect Data Manager Administration and User Guide provides instructions.

Unable to back up share assets

Verify that the share address and path are valid and mountable. Adding a share does not verify that the share can be backed up.
