What a great time for this post/question!!! Thanks for asking it!!
(2) TSM servers, 2 tape Libraries (3494 w/ 15 3590's drives / 2500 cells and a 3584 w/ 6 LTO II drives / 250 cells) 800 nodes (AIX, Windows, Linux) Every flavor of DB or app you can imagine. We backup 2-3TB a day. Total stored in TSM is 90TB, combined database used is 80GB. We invest around 4-8 hours a day on TSM "stuff". TSM like everything else is under staffed...we could be investing about 3 times the amount of people resources on TSM that we currently do. Dave
