CATVMFB - Back Up the Volume Master File

The TLMSVMFU program (CATVMFB procedure) is used to back up the Volume Master File. Periodic backup of the VMF is necessary to aid in its recovery should the VMF be corrupted or lost. The backup procedure is also used to save transactions which occurred since the last backup was performed. The following should be considered when scheduling this function:

• Tape processing does not have to be quiesced to perform a VMF backup procedure.
• The level of tape activity in the data center may determine how often the VMF should be backed up. A high level of activity indicates the necessity for frequent backups.
