When restoring to a virtual system, such as Unitrends Backup, it is required to be configured with storage devices to which data would be restored. Backup devices should be created on the target system prior to the restore. Storage can be internal data stores or external storages like SAN (connected via ISCSI or fibre channel) or NAS.
Because the recovery process will not attempt to connect to any storage, this connection should be made prior to beginning the restore. Depending on the amount of data that has to be restored to the system, the set up could vary. In all cases, if storage is directly added to the virtual system, it cannot be packaged into an Open Virtualization Format (OVF); therefore external storage needs to be added as a data store to the ESX server hosting the virtual system.
Next, a virtual disk must be added to the virtual system using the designation of Added Internal. Set the purpose to Backups by clicking on Settings > Storage and Retention > Storage.
The following scenarios are possible, and depend on the size of vaulted data:
|
Scenario |
Description |
|---|---|
|
Data less than 2TB |
One virtual disk needs to be created on the data store housing the external storage. |
|
Data greater than 2TB, no client greater than 2TB |
Appropriate number of virtual disks need to be created with none greater than 2TB. The recovered system cannot be directly packaged into an Open Virtualization Format (OVF). |
|
Data greater than 2TB, at least one client greater than 2TB |
A floating storage device needs to be used to house client data greater than 2TB. Because the recovered system cannot be directly packaged into an Open Virtualization Format (OVF), this is required. The floating storage device is directly connected to the target system and backup devices are added onto this storage. This device has to be NAS only. |
After storage devices are added to the target system, management privileges need to be granted to the vault, by navigating to Settings > Vaulting > Vault Management.
