Recovery procedures vary depending on the NAS protocol used to create the backup. See these topics for details:
NAS CIFS and NFS backups have the following recovery options:
• | Search Files – Search for specific files in all backups of this NAS that are currently stored on the appliance. Choose files to recover from the search results. |
• | Recover – Select a specific backup to recover all files in the backup group up to the point in time when the backup ran. |
• | Recover Files – Search a backup and choose specific directories or files to recover. |
See these topics for details:
For all recovery procedures, you must specify the target recovery location by selecting an asset and entering the full directory path where you want to recover the files. This location can be the original NAS share, an alternate location on the original share, or another CIFS or NFS NAS asset that has been added to the Unitrends appliance.
For example, to recover to an alternate location on the original NAS share:
The original backup was of this directory:
/mnt/NAS/folder/subFolder1
and you wish to restore to:
/mnt/NAS/folder/subFolder2
enter the full path in the Directory field:
/mnt/NAS/folder/subFolder2
Note: If you enter /subFolder2 only, the files are recovered to the root mount point on the backup appliance (/mnt in our example). This could fill the root mount point and crash the appliance.

The following limitations apply to NAS NDMP recovery:
• | NDMP backups can only be recovered to NDMP devices of the same vendor. |
• | Supported recovery targets vary by vendor. For example, VNXe devices only support full volume-level recovery to the original location. |
Recovery to the original location is supported for all vendors. See the vendor documentation to determine whether you can recover to another location on the original NDMP device, or to another NDMP device that has been added to the appliance as an asset.
• | Point-in-time recovery of the entire backup group is supported. |
• | Recovery of selected files is supported for some NDMP devices from the certified vendors. See the vendor documentation for compatibility limitations. |
• | When performing point-in-time recovery of an NDMP volume, you cannot specify files to include or exclude. The volume is recovered exactly as it was at the selected recovery point. |
• | Recovery of seleced files that contain non-UTF-8 compatible characters is not supported. Instead you must recover the entire backup. |
See these procedures to recover from NDMP backups:
Use this procedure to recover the entire backup.
1 | Select Recover and click the Backup Catalog tab. |
Use Filter Backups to the right to customize the backups that display.
2 | Expand the NDMP asset and select a backup or imported backup copy to use for the recovery. |
To import a backup copy, see To import a cold backup copy or To import a backup copy from the Unitrends Cloud.
3 | Click the Recover button. |
4 | Specify a recovery target: |
Note: Some filers only support recovery to the original location on the original NDMP device. See the vendor documentation to determine which options are supported for your filer.
• | Select an NDMP device in the Asset list. |
Only devices of the same vendor display. Additional vendor compatibility limitations apply.
• | Select a target Volume. |
Only directories on the selected device that are online and have enough space for the recovery display.
• | (Optional) Enter the target Directory to which the backup will be recovered. |
– | The target directory cannot exceed 255 characters. |
– | If the directory entered does not exist, it is created within the selected volume. |
– | If this field is left blank, the backup is recovered to the target volume. |
5 | Click Next. |
6 | Review the job details, then click Save. |
The recovery job is queued immediately.

If you encounter a permissions error when attempting to access an NDMP backup that was recovered to an environment with different permissions, unmount the target volume and remount it with the appropriate permissions.
Use this procedure to recover selected files from an NDMP backup.
Notes:
• | Recovering files is not supported for all NDMP filers. For example, VNXe devices only support recovering the entire backup to the original location. See the vendor documentation to determine whether recovering files is supported. |
