Well, I can't say I'm an "expert" on either, but having done both, I
will say this:

sysback only backs up rootvg, AFAIK. Plus, it's better if files are
not changing when it happens, so we always boot into maintenance mode
to do it (shutdown -m). It doesn't do incremental backups.

For these reasons, sysback would be extremely tedious to do on a nightly basis.

We use both solutions. We make periodic sysbacks of our important
machines (ideally monthly but definitely before and after major OS
changes). Then use TSM to do nightly backups.

We can use the sysback to quickly install a machine right back to its
original system state. We can then restore data via TSM.

=====

Actually, along the same lines, I've never had to do it, but could we
restore an entire AIX system through TSM alone? How would we even do
this? It seems we'd have to install at least a bare OS and at least
the TSM client, right? But then, overwriting its own system files
would be kind of a weird (if not impossible) thing ... any ideas?

For TSM AIX only.

I just recently saw the IBM web site on AIX SysBack System Backup and
Recovery program.

Can someone who either knows both, or uses both of them, point out the
differences/similarities between AIX SysBack and AIX TSM??

TIA.
