"How long do I keep volhist" is related to "How long do I set
reusedelay", both of which are subsidiary to "How far back in time am
I willing to revert my TSM server in the event of a problem?".
If you have a 25-day-old database backup, but your REUSEDELAY is not
set to at least 26 days, then when you -use- the 25-day-old database,
some unknown amount of it will be invalid. Ick. Audit everything?
I suggest deciding on the "How far back am I willing to contemplate
recovering my TSM server" value first, and then setting both
REUSEDELAY and the length of volhist retention with that in mind.
So, if you want 4 days, then set them both at something a little more
than 5. If you want 30 days, set them both at something a little more
than 31.
