Hello everybody, TSM does a pretty good job on the tape management by space reclamation and copying the primary pools to copy pools.
But I'm wondering how I can estimate the size of the library (number of slots, type of drive) to reach this steady state of tape usage. Of course I've got the following information: - total amount of data to be backupped (GB) - the number of versions I keep of the files - space reclamation of tape occurs when there is 55% free space on the tape How can I estimate the number of tapes I'll be needing based on this info? Are there any rules of thumb to size the library? Do I still need additional info to calculate the library size? Any suggestions /hints are more than welcome. Thanks in advance, Kurt
