Thanks in > advance for any suggestions you may have! > If you have several policy domains, each writing to a separate primairy storagepool, you could have separate copypools as well. In this way you could eg. have your two or three 'must be recovered in 10 hours or so, otherwise DR is useless' systems write to a smaller copypool. This will give you some overhead, but could greatly reduce the number of tapemounts needed when restoring from copypool volumes. > Joni Moyer > Systems Programmer > [EMAIL PROTECTED] > (717)975-8338 -- Met vriendelijke groeten, Remco Post SARA - Stichting Academisch Rekencentrum Amsterdam http://www.sara.nl High Performance Computing Tel. +31 20 592 8008 Fax. +31 20 668 3167 "I really didn't foresee the Internet.
