For some environments, yes.  But not for all.

Even people who backup once overnight, still have to do

(1) backup stgpool to create copypool tapes.
(2) tape reclaims
(3) inventory expiration

All those things change the TSM DB.

And some environments are really 24 x 7:

One of our TSM servers does desktop backups of 500+ clients.  Backups are
spread over 24 hours a day, so for that environment, the TSM db is changing
EVERY MINUTE.  Really.

And consider also the people who have implemented the HSM client - in that
environment, just having a user "touch" a file is enough to bring it back
from TSM storage to client storage, and the TSM DB is changed.

In either of those environments, losing 12 hours, on average, of DB changes
can be devastating.
