Data in a split BCV can be backed up to tape during the services.
To secure consistency of BCV data, the services should be stopped temporarily when the BCV is split.
Consistency of Snapshot Data
When detaching BCV while the services are operating, data consistency must be secured through the method specific to that software, such as a file system and a database system, which manages volume data. For details, see "Ensuring Consistency of Snapshot Data."
When Restoring from the BCV
The following conditions must be met when performing a backup to the BCV (disconnecting the BCV).
Back up all disks registered with the backup target class (except for disks that are disconnected and in SWAP status) to the BCV. For disks not backed up to the BCV, it is necessary to disconnect from the class before the BCV is detached.
Before backup to the BCV is completed for all disks within the class (except for disks that are disconnected and in SWAP status), do not change the object configuration or status in the class.
When Not Restoring from the BCV
When restore is always from tape instead of BCV, it is not necessary to perform disk disconnection and reconnection in the backup process.
