Backup storage

Use the Configure > Appliances > Storage tab to manage your appliance's backup storage. Supported storage procedures vary by Unitrends appliance type:

Recovery-Series physical appliances come with a set amount of backup storage. You cannot add backup storage to the appliance.
UEB virtual appliances are deployed as virtual machines. During deployment, the initial backup storage was created using either a virtual attached disk, a SAN LUN, or a NAS share. After initial deployment, you can add more backup storage as desired. See About adding backup storage to a UEB appliance for details.

Instant recovery write space

When configuring backup storage, you must determine the percentage to use for backups and the percentage you wish to reserve for instant recovery. Because your appliance is designed to retain as many local backups as possible, you should reserve instant recovery space soon after initial deployment. If necessary, you can allocate instant recovery space later, but doing so may require the appliance to purge local backups to make room for the newly allocated instant recovery space.

The storage reserved for instant recovery is used to store a disk image, known as a recovery object, based on the backup selected for recovery. Once the instant recovery completes, the recovery object should be torn down, leaving the reserved space available for other instant recovery processes.

For more information, see Instant recovery.

For both Recovery-Series and UEB appliances, you can view backup storage and modify the amount of storage allocated for backups and instant recovery.
