*************************************************

I have most of my customers use the MAPICS Schedule Backup to Disk - it is
much faster.  Then they use the AS400 Job Scheduler to save user libraries
(including the MAPICS libraries) as an extra backup.  They backup to tape
the previous night's backup-to-disk.  The customers do not run a 24/7 shop.

Be aware that the "PRE" Backup command runs prior to getting a dedicated
mode.  The "POST" Backup command runs while in dedicated mode.

We are also looking at creating a scheduled job that will check to see if
the MAPICS Backup to Disk ran (looking at the ZSVCTL dataarea).  This will
run a separate backup if the MAPICS Backup could not get dedicated mode or
batches were not closed. This is only for customers that do not run the
AS400 Scheduled Library backups.

I have a pre-backup command that ends jobs with a lock on sysctl and cleans
up abend records
in jobact. I formerly used a post backup command to back up the remaining
libraries on mmlist
but found this was keeping MAPICS dedicated that much longer. I changed the
end of tape
option to 2 (leave) and now I run that command through the OS/400 job
scheduler. These
remaining libraries are being backed up with the save-while-active option
and MAPICS is now
dedicated for only 30 minutes per day. (The Magstar 3570 also cut our backup
time
dramatically)
