Maybe the best idee I heard untill now, If you're planning a major upgrade, switch on collocation on your storagepool first and then run a selective (full) backup of your system, this will bring the restore time down to the time it takes to mount about 8 tapes and read them....
(and switch collaocation off again :) -- Met vriendelijke groeten, Remco Post SARA - Stichting Academisch Rekencentrum Amsterdam High Performance Computing Tel. +31 20 592 8008 Fax. +31 20 668 3167 "I really didn't foresee the Internet.
