The mail system resides on an AIX server. The storage is in a SAN !
For the OS, it is irrelevant since you would have to reinstall AIX, anyway
!.
However, we have seen lots of applications that store their files and data
as part of /etc, /usr, /home, etc. We even have one "client" that decided
to link/share /usr/local among many systems.

I don't agree. You need image backup for the disks with mails (I hope you
don't store them on the os disks) and incremental backups for the os
files.

Was this for the os of the client or the os of the TSM server?

Ok, you are right, there is no single solution for the problem.
