Recovering NAS Backups

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 and/or files to recover.

You can recover from a backup by using the Backup Catalog or the Backup Browser. To recover from an imported backup, from a backup copy, or to search for files across multiple backups, you must use the Backup Catalog. See these topics for details:

Specifying the target recovery location

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 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.

To search multiple backups for files to recover

Click Recover > Backup Catalog > Search Files.

For Type, select Backup.

For Asset, select the NAS whose files you want to recover.

Enter additional criteria and click Search.

All backups of this NAS stored on the appliance are searched for matching files.

In the results list, click to select files to recover.

Note: All files you select must be from a single backup. Check the Backup ID to determine a file's backup. If you select files from multiple backups, the Save button becomes disabled.

Click Next.

Select the asset where the files will be recovered.

In the Directory field, enter the full path where the files will be recovered.

For details, see Specifying the target recovery location.

Click Save.

Click OK to close the Notice message.

Recovering NAS NDMP backups

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.

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 selected files that contain non-UTF-8 compatible characters is not supported. Instead you must recover the entire backup.

You can recover from a backup by using the Backup Catalog or the Backup Browser. For imported backups and backup copies, you must use the Backup Catalog. See these topics for details:
