>Dies BRMS allow saves to SAVF? Yes ... A BRMS control group can be defined specifying that a *SAVF be used. Control groups can be defined that will then copy these *SAVF's to tape. Information for objects saved to *SAVF's is stored in the BRMS database so individual restores can be performed without having to mount media. BRMS is also "smart" enough to understand that a library has been created since the last FULL save process was run. In this situation it performs a SAVLIB command instead. BRMS can also perform 2 different types of incremental backups: *CUML Incremental backups are cumulative, that is, when an incremental backup is specified, all changed objects since the last full backup are included in the saved objects. *INCR Incremental backups are not cumulative, that is, when an incremental backup is specified, all changed objects since the last incremental backup are included in the saved objects. >From a recovery point of view the *CUML option lets you recover using fewer tape mounts and is the option I have always used. I've used a FULL plus INCREMENTAL save policy successfully for many years. I perform a disaster recovery test each year and I'm able to recover to the point of the last journal receiver BU boundary without issue. It has actually become quite routine. There is a gotcha in recovery using the incremental strategy though. For example, lets say you do a full save of library " A " on Sunday. Delete several objects out of library " A " on Monday and then do an incremental BU on Tuesday... When you recover library " A " using these 2 tapes, the object deleted on Monday will restored when you restore the full save, and restoring the incremental save will not delete the objects that were removed from the library on Monday.

We have a procedure that does a SAVCHGxxx every night, with the previous run's date and time for reference date. We save to SAVFs, then copy to IFS and compress with gzip before writing to CD. We do libraries individually. One lacuna I just noticed is, a new library is not saved with SAVLIB - objects in it get caught by the SAVCHGOBJ, and restoring might be a problem if the library does not exist. Not too much of a problem - recovery is a manual process for now. One problem is that the reference date function is specified differently in all the various SAVCHGxxx commands - Yuk! But we've been able to recover from 2 inadvertent DLTLIB's Dies BRMS allow saves to SAVF? Regards Vern
