Dell Powerscale
To provide proper integration of Veeam Backup & Replication with Dell PowerScale (formerly Isilon) to implement the NAS backup functionality, consider the following:
- The Dell PowerScale system must be licensed for SnapshotIQ. Otherwise NAS integration will not work.
- The PowerScale service account is used to add the Dell PowerScale system to Veeam Backup & Replication, as described in Adding Dell PowerScale. This account is used only for registering the storage system in the backup infrastructure and further storage rescans. You cannot use it for NAS file share backup and restore.
- Starting from Dell PowerScale 9.5, Veeam Backup & Replication supports SmartConnect.
- We recommend that you create a custom VeeamStorageIntegration role to group all necessary privileges. This role must be created in the System access zone. For more information on access zones, see the Dell documentation.
Add the following privileges to the VeeamStorageIntegration role:
Privilege ID | Read Only | Comments |
|---|---|---|
ISI_PRIV_LOGIN_PAPI | True | Used to log in to the Platform API and the web administration interface. |
ISI_PRIV_AUTH | True | Used to configure external authentication providers, including root-level accounts. |
ISI_PRIV_DEVICES | True | Used to create new roles and assign privileges. |
ISI_PRIV_JOB_ENGINE R/W | False | Used for array Change File Tracking report scheduling for changelist API call. |
ISI_PRIV_NETWORK | True | Used to configure network interfaces. |
ISI_PRIV_NFS R/W | False | Used to update export rules. |
ISI_PRIV_SMB | True | Used to configure the SMB server. |
ISI_PRIV_SNAPSHOT R/W | False | Used to schedule, take, and view snapshots. |
For more information on privileges, see the Dell documentation.
You can use the following command to check privileges added to the VeeamStorageIntegration role:
isi auth roles view VeeamStorageIntegration |
Make sure that you make the service account to be used for NAS integration a member of the VeeamStorageIntegration role.
- To enable backup and restore of SMB file shares, additionally do the following:
- Grant minimum read access to SMB file shares for the account that will be used for NAS integration. That will allow backing up SMB file shares.
- Grant "run as root" access to SMB file shares for the account that will be used for NAS integration. That will allow restoring SMB file shares.
Consider that the PowerScale BackupAdmin role is not enough for backup and restore. It is mainly used for SMB access and enables backup and restore of files from /ifs. It does not propagate down to subfolders and therefore cannot be used to backup anything, but the system access zone.
- To correctly use SmartConnect for NAS backup, consider the following:
- Enable SmartConnect on the storage system as described in the Configuring SmartConnect section in the Dell documentation.
- Configure DNS and DNS delegation as described in the Set up DNS for SmartConnect section in the Dell documentation.
- Add the storage system to the backup server as described in Adding Dell PowerScale.
- Add general-purpose backup proxies to the backup infrastructure. We recommend adding as many general-purpose backup proxies as many Dell Powerscale storage nodes you plan to use for backup.
Dell PowerScale SmartConnect helps distribute the load among storage nodes: SmartConnect provides clients different IP addresses from different nodes to work with the storage cluster in parallel. If you do not use SmartConnect, Veeam Backup & Replication will use single IP address during backup, which can cause significant delays.
