The on-host snapshot set can be used to quickly recover a storage group after logical corruption. You can restore a storage group either to the Point in Time (PIT) that the vxsnap restore command was last refreshed or, using current transaction logs, to the Point of Failure (POF) of the database. Additionally, you can recover a single database to the point of failure.

You can use either the VSS Restore Wizard from the VEA console or the vxsnap restore command. Both the VSS Restore wizard and vxsnap restore command integrate with VSS to notify the Exchange VSS Writer to prepare for the restore before the snapback operation and then to complete post-restore processes afterwards.

After completing the recovery, you refresh the snapshot set.
