Hi Del!
I might be wrong because I do not use TDP 4 Mails by myself, I am only RTFM,
but I´d think about simplified "solution 2 by Del":
Background:
I think the only reason for having different requirements for monthly an yearly
backups is TSM storage space,
if this were not a problem keeping monthly backups for as long as yearly
backups should be kept would be preferrable.
a) create only 1 NODENAME
b) define
INCLUDE "*\...\full" EXCH_STANDARD and maybe
INCLUDE "*\...\incr" EXCH_STANDARD and maybe
INCLUDE "*\...\diff" EXCH_STANDARD
appropriately to your regular (daily) backup requirements
c) define
INCLUDE "*\...\copy" EXCH_MONTHLY_AND_YEARLY
appropriate to maximal combined requirements of your monthly AND yearly
requirements
AND have EXCH_MONTHLY point to separate TSM storage pool (EXCH_VERYOLD)
d) on regular basis (maybe yearly) check out all full tapes from EXCH_VERYOLD
storage pool from library.
Disadvantage: reclamation of backup storage pool issues because of offsite
tapes in primary storage pool,
but this can be solved as well.
You will end with a bit less automated restore (only) for very old data
but with very clear and simple concept for everyda/everymonth backup operations
and with more granularity (monthly) even for data older than a year.
I am interested in your thoughts and doubts about this configuration!
regards
Juraj
