It's probably close. Deranged people such as myself might comment:
* If you are doing weekly backups, these numbers are way too high.
* If you sometimes do more than one backup in a day, the numbers could
be too low.
* If you want to do restores from the last 60 backups, 60 would be
right for verexists, but 59 would be sufficient for verdeleted, etc.
* It sort of depends on what you want to accomplish. Maybe a client
expects 60 days to be 2 months. Maybe bump 60 a little. Maybe you
backup every day, but client doesn't see a problem on weekends, so
maybe bump 60 a little. Maybe client tries to restore today, runs out
of time and comes to you tomorrow for help. Maybe bump 60 a little.
Of course, if you can identify the files which need this PIT
requirement, then considerable *SM DB and STGpool space and processing
time might be saved if you have a special management class for the 60-
copy files and something considerably less as "standard" ... but then
the client risks making a poor decision. :-)
