The ca_restore command includes the following VSS agent database options:
ca_restore -source <vss_path>
-dest [-vss [-vss_auth]]
Specifies to restore your data from a VSS backup.
For a VSS restore, this option forces the restored copy to become the “authoritative” version. This means that, even if the restored replica set is older than the current replicas, the older data will be replicated to all of its replication partners. Authoritative restore is typically used to restore a system to a previously known state or if an administrator has accidentally deleted objects and that change has been replicated to all of the domain controllers. If the administrator is able to recreate these objects easily, then this should be chosen over an Authoritative Restore. An Authoritative Restore will not overwrite new objects that have been created after the backup was taken.
This option is only applicable if the VSS Writer supports Authoritative Restore, like the DFS (Distributed File System) Replication Service writer. If the writer does not support Authoritative Restore, this option will take no effect.
By default, Arcserve Backup uses the non-authoritative method.
