Backing Up and Recovering Catalogs

Because catalogs are essential system data sets, it is important that you maintain backup copies. The more recent and accurate a backup copy, the less impact a catalog outage will have on your installation.

Besides the backup and recovery of BCSs, you should also develop a strategy for backing up VVDSs, VTOCs, and VTOC indexes.

This chapter considers the backup and recovery of BCSs and VVDSs, and indirectly, the VTOC. For more information about data set back up and recovery, see the following:
