The CA Vtape BSDS is a critical system file. To ensure recoverability after a hardware failure, maintain a backup of the BSDS.
Back up the BSDS after batch processing completes. Then back up the Tape Management Database also.
A synchronized set of these backup data sets is not required. You can take the backups within a few minutes of each other.
Make the backups close together so that the current Virtual Volume information in the BSDS matches the Tape Management Database information. If the Virtual Volume information is too far out-of-sync, CA Vtape may not be able to access Virtual Volume files without manual intervention. Your disaster recovery efforts are then much more complicated.
Send these backups off-site for disaster recovery. Do not write the backups to CA Vtape Virtual Volumes.
