We start backups around 8pm; most clients are done by 4am when we start backup
storage pool. The tapes are ejected between 11am and 2pm. In the remaining
time we do migration, expiration and most of the reclamation. Our only issue
is reclamation does not always completely finish, but it is close enough to not
cause a problem.
We are upgrading the hardware on Monday to a p550, we figure 6 years is enough
to get our moneys worth out of the 6H1.

How long does your whole backup cycle take ? From the time the first backup
starts to when the database backup ends ( or when the DRM module is executed ) ?

How many clients, how much data per night and how big is your DB?
We have a 120GB db, about 2.5TB per night and 600 clients running on a
6H1 4 CPU and 4gb RAM. Our disk storage pools are about 1.8TB with a
VTL for primary storage. A 3494 is used for copy tapes.
I think I am supposed to say "it depends" somewhere, so there it is...

It looks like, after many years on the z/VM platform, we are finally
going to make the "leap" to TSM on Power (IBM Pseries) and AIX. Does
anyone have any suggestions as to configuration and sizing of the box
and disk space? We also like to retro-fit our 3494 ATL to connect to
the Pseries. Anyone doing anything like that?
