Both users and the HSMS administrator can reduce their backup times, provided they observe the information provided below.
Restrict the file set effectively by using the functions for file selection
Decentralized management of SF pubsets
Do not allow the archive directories to become unnecessarily large and, if required, split them in a sensible manner (for example according to catalog IDs or UFS drives)
Between full backups, only perform incremental backups or saves after catalog entries have been modified
Reduce save time through parallel operation of MTC drives
For BS2000-UFS backup, utilize multiplexing
Reduce downtime of the application by saving “frozen” copies (BACKUP-FILES with CCOPY)
Improvement of I/O operations (maximum tape size and linkage of devices)
In shared pubset operation, have requests executed on the master computer (prevents temporary retry lockouts when sending a large number of catalog operations)
Reduce report scope as far as possible when large file sets are used (with REPORT= *SUMMARY instead of *FULL)
Work without restart points (WRITE-CHECKPOINTS=*NO)
