Hi floks,
 Why i wanted to know more about backupset ?

Our setup : AIX4.3.3 , TSM 4.1.4.2 , 3575 Auto library.
Recently i had a problem with Expire inventory . contacted IBM support (one
to many). They suggested to apply fix 4.1.4.2, I have done it. Still
expiration problem persists. One fine day my TSM server crashed. I tried to
up the server and It never listen to me. Finally , i had to restore most
recent backup. But, TSM keep crashing every day at mid night. I asked IBM
support to escalate this problem (expiration and corrupted DB pages) to
L2/L3, It took  weeks time. They suggested me to AUDIT DB with fix=yes.
nope. they again come up with UNLOADDB/LOADFORMAT/LOADDB.......after few
days....... They asked me to EXPORT/IMPORT all nodes . Even this didnot
worked out. After all this, they said its a known bug and asked us to find
good copy of DB (which we dont have) or rebuild TSM from scratch.
Yes, we have dicided to rebuild from scratch. (no other option)

so *SMers, I would like to know more about backupset. i know little about
it. can i create a backupset for each node and check out those tapes
outside. rebuild TSM from scratch with leftover tapes. Later, check in
those tapes having backup sets and make use of them  with newly built TSM
server. This way i may not loose much data except API related DB2 backups.
Guys!!!!!!!! As im not clear on this option , i request you to give me more
detailed information about this.

Your reply in this regard is highly appriciated.
Thanks in advance.
Regards
Sreekumar.
