Before you restore virtual disks, check the following prerequisites:
- You can restore virtual disks from a backup that has at least one successfully created restore point.
- During the virtual disk restore, Veeam Backup & Replication turns off the target VM to reconfigure its settings and attach restored disks. It is recommended that you stop all activities on the target VM for the restore period.
- You cannot mount restored disks to a VM that has one or more snapshots.
- If you want to scan virtual disk data for viruses, check the secure restore requirements and limitations.
- On non-Microsoft Windows SMB3 storage, for example, Tintri, Veeam Backup & Replication may display the "Failed to disable integrity bit on disk N" warning during virtual disks restore. You can ignore this warning for non-Microsoft Windows SMB3 storage.
If you back up a VM with vRDM disks, Veeam Backup & Replication converts them into VMDK files. Thus, when you restore a vRDM disk, Veeam Backup & Replication will restore it as a VMDK file. If you want to preserve the vRDM format for restored disks, use Quick Rollback. For more information, see Quick Rollback section.
