This is the last step in our nightly back job. It generates a report we find useful.

DSPLOG     PERIOD((*AVAIL *CURRENT) (*AVAIL *CURRENT)) +  
             OUTPUT(*PRINT) MSGID(CPC3701 CPF3771) /* +   
             Libary save and not saved messages */

Are you bringing the system into a restricted state, then saving the entire system? Are you saving a group of libraries while the system is active?

Some time ago I implemented Save While active and Incremental (Save Changed Objects Only). The reduction in System Unavailability with the Save While Active only was from 6hrs to under 1Hr. In our production environment I have not implemented the Incremental Backup yet, but that could also reduce Unavailable time further.

1,,,,, Do not save access paths on whatever Save command you are using. If you have many logical files or logicals over large files it will cut down backup time,

2…… If you are on V5R4 ensure that you are not saving Spool Files. If you have alot of outques and you are saving spool data that will increase backup time.

We were able to significantly shorten out backup time by identifying libraries with static data files (like storage libraries for scanned images) that can be backed up once to tape – and eliminating them from the daily backup procedure.

When this is done, system is free for user’s producton, and you can copy the virtual tape image to a physical image, eventually running with low priority.
