David E Ehresman <[EMAIL PROTECTED]> on 08/13/2002 05:10:47 PM Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc: (bcc: John Naylor/HAV/SSE) Subject: Re: Restore backupset take very long >Will I see restore improvement on >backupsets created with version 4.1.x.x by upgrading to 5.1 or will I only >see improvement on backupsets created with 5.1? > I am migrating from MVS TSM 4.2 to AIX TSM 5.1. As part of that process, I am changing from backupsets to move nodedata as the means to consolidate selected filespaces onto a minimum number of tapes. The generate backupsets were taking nearly 24 hours to run but the equivalent move nodedata ran in under an hour. I don't know how much of that improvement is due to the MVS -> AIX move, how much due to TSM 4.2 -> 5.1, and how much is due to backupset -> move nodedata. I do think it would be worth your while to do the test in your environment to see if it helps.
