If volume data is damaged, it can be restored from tape.
Data can be restored while service is stopped and the application volume is not in use.
In this configuration access cannot be gained from backup server Node3 to disk sdb. Therefore, after data is restored from tape back to sda while sdb is detached temporarily, resynchronization copying from sda to sdb must be performed by reattaching sdb. When access can be gained from Node3 to both sda and sdb, it is not required that sdb be detached temporarily since data can be restored from tape back to both sda and sdb. For details on this restore method, see "Backing Up and Restoring a Logical Volume with No Replication."
