Thanks for your reply.

I am not worried about migration because I do a copy tapepool to copypool
later on.

My schedule is
.  ovenight backups (diskpool is large enough, no migration - very large
files direct to tapepool)
.  diskpool to copypool
.  tapepool to copypool
.  backup database
.  move drmedia etc
.  migrate diskpool to tapepool
.  expire inventory
.  reclamation

My concern is this: when the first two overlap, will the files that are
backed up (to the diskpool) after the "backup stgp diskpool copypool"
started still be copied to the copypool?

Regards
     Geetam

Hi Geetam,

Yes, you may have a weakness in the routine here.  You need to factor in
some BACKUP STG TAPEPOOL COPYPOOL commands to your routine in order to
catch files that come in and migrate before you do the backup stg.

One good sequence is:

backup stg diskpool copypool
upd stg diskpool hi=0 lo=0    { trigger migration }
upd stg diskpool hi=90 lo=80  { reset to desired levels after migration
                                  completes }
backup stg tapepool copypool
backup db ...            { incr/full as required }
move drm  ...            { in operation on your site }

...  enjoy rest of day :  doing reclamation, inventory expiration, other
houskeeping tasks as required for your regular adsm operation.

Regards, Sheelagh
