If master volume data is damaged while the master volume for the services operation and the proxy volume are in the joined state, the proxy data is also damaged. In this case data can be restored from tape back to the master volume.
Data can be restored while the service is stopped and the master volume is not in use.
This sub-section shows an example when access can be gained from backup server Node3 to all of the disks constituting master volume Volume1.
When access can be gained from backup server Node3 to all of the disks constituting master volume Volume1 and the disk unit's copy function is used to synchronize a master and a proxy, parting proxy volume Volume2 is not required to restore data from tape.
When access cannot be gained from the backup server to the disks constituting the master volume, while proxy volume Volume2 is parted, copy data from tape to the proxy volume, and then restore master volume data using the proxy volume.
