With Instant VM Disk Recovery, you can immediately restore VM disks from a backup file and publish them to the production environment.
Use Instant VM Disk Recovery if you need to:
- Recover a VM disk, not an entire VM. Otherwise, use Instant VM Recovery.
- Recover a VM disk and keep the target VM (to which you want to attach the disk) turned on. If the VM can be turned off, use Virtual Disks Restore.
Veeam Backup & Replication performs Instant VM Disk Recovery using vPower technology. The main steps of Instant VM Disk Recovery are the following:
- Veeam Backup & Replication checks whether the vPower NFS datastore is mounted to the ESXi host and contains VMDK files of the recovered disks.
- [If you replace an existing disk] Veeam Backup & Replication unmounts and deletes the existing disk.
- The recovered disks are connected to the target VM.
- Veeam Backup & Replication initiates creation of a protective snapshot for the target VM. If Instant VM Disk Recovery process fails, the protective snapshot guarantees no data loss.
- Veeam Backup & Replication writes changes made to the recovered disks to redo logs on the vPower NFS server.
The Instant VM Disk Recovery is a process that must be finalized. First, test the recovered disks and then decide whether to publish them to the production environment or stop publishing the disks. To publish the disks, Veeam Backup & Replication uses the Quick Migration mechanism. For details, see Quick Migration.
