The following updates have been made to DASD Backup Supervisor version 2.5. Visit the Rocket DASD Backup Supervisor User's Guide for detailed information about using these features.
Advanced copy functions
DBS advanced copy functionality has been enhanced to include two additional selections for copy volumes that can improve the pairing of production devices to flash copy targets.
The first option ZPOOLED assigns flash copy targets based on device capacity (i.e., cylinder count) similar to the POOLED specification in PARMLIB(COPYVOLS), but it is not limited to either online or offline devices. Additionally, this new option checks eligibility of the target device before pairing it to a production device.
The second option FCMGR imports volume pairing information from IBM Flash Copy Manager.
New backup and restore statistics
New backup and restore statistics can now provide key information that can be used to improve product performance
Volume compression statistics
DBS now records additional statistics concerning tape hardware compression for DASD backups. The new compression percentages help DBS better forecast backup tape usage; thus, the functionality and applicability of the BACKUP-TAPEMAXIMUM- UTILIZATION-PERCENT parameter is improved.
