Our backup needs are fairly well understood (ie. we have one or
more answers for the questions listed below etc.). What I'm looking
for are possible real world "linux" backup solutions that folks on
this list may have actually implemented based on thier own
specific needs; which may be somewhatdifferent from mine, but,
that's OK. I can interpolate.

1T/box. Anyone have any recent experience/wisdom for such?
There are a number of possible backup solutions available
for Linux. Whether or not they are a good solution for your
particular case is dependent on a few things (that you should
nail down anyway):
1 How much time can the backup take? Less time is more money.
Backing up that much data can take days with a wimpy
solution.
2 How often do backups need to be done? Every day? Week?
3 What would you like to backup onto? Different media have
different costs and size limits.
4 Do you need to be able to do a 'bare metal' disaster
recovery of the entire system? Or do you only need to
recover files?
5 Is there anyone in the current organization that has the
skill set necessary to setup and operate the backup system?
(This may seem a silly question, it's amazing how often
the answer is no.)
6 Are you backing up a database? Many databases require a
special backup procedure in order to insure that what
you backup is not corrupt due to active transactions
happening in the middle of the backup.
7 Does the backup have to happen on a live system or can
the system being backed up be taken completely offline?
8 How much can you spend? Solving this well is probably
going to cost some serious bucks just in hardware alone.
Hope this helps.
