Hi Brian, We Restored a 130 GB database in 2 hours due to multiple restore sessions on a Gigabyte backbone. Now, the DBA had to kick off 6 separate streams and since a great deal was on tape some of the streams waited for each other, but I'd rather have it waiting then not doing anything if it had been single streamed. I have also noticed (since we are no-collocated also) that with multistreaming the no-collocation can really help if you have enough tape drives and memory on the client (I crashed 1 client due to too many restore streams). In fact the restore took 1/2 time the backup did due to the multistreaming. The client was 4.2.1.11 and the Server is 5.1.1.0. Can't wait to try a 5.1 client.

Little different than the TSM 5.1 multi-stream backup / restore. -----Original Message----- From: brian welsh [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 19, 2003 3:22 PM To: [EMAIL PROTECTED] Subject: Multiple restore sessions Hello, AIX 5.1, TSM 4.2.2.8 (soon upgrading to 5.1) I'm wondering if someone have good experiences with multiple restore sessions. We have 4 drives in our library. When there are no other processes and a client is starting a restore and files are spread over several tapes, will there be up to 4 simultanious sessions for restoring? Is it necessary to set collocation off, before you can use multiple restore sessions, or with collocation enabled and data for one client spread over more tapes it is also possible to get multiple restore-sessions? Thanx, Brian. _________________________________________________________________ Hotmail en Messenger on the move http://www.msn.nl/communicatie/smsdiensten/hotmailsmsv2/
