Recovering CA Vtape Subsystem › Prepare for Disaster Recovery

Prepare for Disaster Recovery

At the primary data center (PDC) backup the product libraries, including the parmlib, the tape management system catalog, and the BSDS.

Consider the following backup issues when planning for disaster recovery:

• Back up copies of the product libraries, including parmlibs, the tape management system catalog, and the BSDS1 control data set.
• Back up the BSDS control data set and the tape management catalogs at relatively the same time, to keep them synchronized. You do not have to stop CA Vtape to perform the BSDS backup.
• Schedule these backups to run as often as your business requires. At a minimum, run the backup once a day after the disaster recovery data is created. Note the date and time when the backup started.

The backups provide point in time snapshots of control information about the Virtual Volumes for your DRC. Virtual Volumes that are scratched or modified after the backups are made are not recorded in the tape management system or CA Vtape control data sets.
