About VMware virtual machine disk restore
NetBackup supports the restore of individual VMware virtual machine disks to the following destinations:
To the original VM | You can restore the disks to the same VM from which the disks were backed up. You can either overwrite the original disks or attach the virtual disks without overwriting the original disks. NetBackup creates a temporary VM to which it restores the virtual disks. Then, NetBackup attaches the virtual disks to the existing, target VM. Finally, NetBackup deletes the temporary VM after the disk or disks are attached successfully. |
To a different VM | You can restore the disks to a different VM. NetBackup creates a temporary VM to which it restores the virtual disks. Then, NetBackup attaches the virtual disks to the existing, target VM. Finally, NetBackup deletes the temporary VM after the disk or disks are attached successfully. |
To a new VM | NetBackup creates a new virtual machine and restores the specified disks to the new VM. The new VM is intended to be a container for the restored disks. It does not have enough resources to run most operating systems. After the restore, you should attach the restored virtual disks to a VM that can support them and then delete the restore VM. |
The following table identifies the two restore methods and their limitations:
Table: Virtual machine disk restore requirements and limitations

NetBackup 7.7.3 or later master server and backup host must perform both the backup and the restore.
Sufficient storage must exist for the restore.
