The CA Vtape BSDS1 should be considered a critical system file. Maintaining a current backup of the BSDS1 is critical to insuring recoverability if the hardware unexpectedly fails.
The BSDS1 is typically backed up after batch processing is complete. The Tape Management Database should be backed up at this time also.
A synchronized set of these backup data sets is not required. You can take the backups within a few minutes of each other.
The backups need to be taken close together so that the current Virtual Volume information in the BSDS1 matches the Tape Management Database information. If this information is too far out-of-sync, CA Vtape may not be able to access Virtual Volume files without manual intervention and your disaster recovery efforts will be much more complicated.
These backups should be sent off-site for disaster recovery. These backups should not be written to CA Vtape Virtual Volumes.
