I have virtually the same setup.
Answers:
1. I don't because I have big Oracle DB's to backup.
2. No need.
3. I started out with 18N2 in January. Started having some problems
mainly tape error left tape in drive. CE upgraded to 22UD over a month
ago - no problems since. (I have (8) LTO FC-AL tape drives and IBM tapes.)
4. Either, but I generally let CE do this stuff.
5. Don't know. Haven't done it.
6. There are several ways this can be accomplished. One is to do a
SELECTIVE backup instead of incremntal and select everything.
Depending on what you want to do there are generally many ways to do
it.
7. The purpose is this. You have a Primary tape pool. Make copy of it
to Copy Tape Pool. Then once a day or whatever you frequency is, take
out the copy pool tapes and send to offsite Vault. If you have DRM, it
helps with all this and keeping track of tapes and showing you which
ones to bring back when they have expired/been reclaimed.
This is for Disaster Recovery purposes. If you have some data deleted, you can
restore from Primary pool in library. If building gets burned down, you have
copy
of all your data offsite and can restore everything once you get hardware
installed.

Environment: TSM 4.2.x on an AIX 4.3.3 ML10 server (660-6H1) with a 3584-L32
and a 3584-D32 expansion frame.
In the process of setting it up, which is a luxury that I'll have only once
to get it right. :) So, some questions (since I am still coming up to speed
on *SM).
1) Is there any particular reason to set a max file size for a disk stgpool?
(Assuming a setup where disk stgpool will migrate to tape stgpool)
2) Should the TSM server have its own stgpool for backing up itself?
3) I've heard mixed things about 358x firmware version 22UD... I think we
have 18N2 (but not near it right now to confirm), although what I've
heard about 22UD is generally (but not 100% in agreement) positive. Stable?
4) Whom is supposed/allowed to upgrade firmware? IBM CE only?
5) The only docs for firmware upgrade references a NT/2000 box and the
NTUtil application, whereas I'm in an all-UNIX (AIX and Solaris, although
I do have a laptop with Linux and Windows XP if need be) environment, so
wonder how to upgrade the firmware without Windows if it's even possible.
6) To *SM, all backups are incrementals (except for the first backup of a
new client), is my general understanding. Is there a way to force a full
backup of a particular client as an one-time operation? I'm guessing maybe
not, but thought I might try asking, anyway. :)
7) The biggest single question... I don't have a real good understanding of
the purpose of copy stgpools. I've read a lot of documentation -- hundreds
of pages of multiple docs, re-read, read old adsm-l mail, Google searches,
etc... but still just don't quite 'get it'. I can set up HACMP clusters,
debug really obscure things, but this eludes me. ;)
What I want to do is:
client -> TSM server -> disk stgpool -> (automatically migrate to tape
based on space utilization of disk stgpool) tape stgpool
That's the general concept of what I want to achieve. Is a copy stgpool
really needed, to be attached to either one of the primary stgpools?
I was under the impression that a copy stgpool was something you wanted
when you wanted to copy a primary stgpool so that you could send it to
another stgpool when ready (based on whatever trigger...space, date),
such as in a disaster recovery scenario?
