This section describes how data is restored in AdvancedCopy Manager.
The restoration operation refers to restoring data from a backup volume to a transaction volume using backup carrier management information.
Data restore from a backup volume refers to using the OPC function provided by ETERNUS Disk storage system to restore data from a backup volume to a transaction volume.
If the data on a backup volume under carrier management is restored to a transaction volume, the carrier management information does not change.
Note that data is restored to a transaction volume that was the backup source. However, you can change the restore destination.
Note
Data updated between the last backup and a subsequent restoration is lost as the transaction volume is overwritten by the backup volume.
