About restoring the multi-attach volumes
NetBackup for OpenStack supports multi-attach volumes for backup and restore. With this feature, you can share one volume with the multiple virtual machines. For more information about multi-attach volumes, see the OpenStack documentation.
During the backup of virtual machines with multi-attach volumes, each virtual machine is backed up separately. Hence, when restore operations on virtual machines with multi-attach volumes is performed, the restored volume has a multi-attach property set but is not shared by default.
For example, you have a multi-attach volume that is attached to four virtual machines protected by four different protections. You take the backup of four virtual machines with these protections. When you restore the instance from the snapshot or backup copy, it restores four virtual machines with four separate volumes with the multi-attach property set.
