gbsd Posted March 7, 2006 Report Share Posted March 7, 2006 Howdy, I have noticed some large variances in backup performance. Would appreciate any suggestions or tips. Backup server is a dual 1.33ghz G4 xserve 2 gb ram with 5T xraid. Backing up 20 dual 1.33ghz G4 xserve 2gb ram over 100mb fiber WAN. retro v6.1 I am backing up sharepoints, no compression, no verification, everything except cache files. A busy server may have 1 + GB of data(incremental) at 600MB/s one day and 90MB/s the next day for approx. the same amount of data and number of files. Backups are at night. No know network activity such as scanning or imaging happening during this time. We have 3 xserves on this local LAN and even with these (gigabit switched) we are seeing variances between 100MB/s and 350MB/s. tia Link to comment Share on other sites More sharing options...
pvision Posted March 8, 2006 Report Share Posted March 8, 2006 What OS versions and what Retrospect versions? What are you backing up to? Are all the machines on the same subnet? We need way more information... Link to comment Share on other sites More sharing options...
gbsd Posted March 8, 2006 Author Report Share Posted March 8, 2006 Most servers on 10.3.9, a couple on 10.4.3 Retro server v6.1.126 Retro clients v6.0.109 (10.3.9) and v6.0.110 (10.4.3) Backing up to 5T xraid Most servers are on different subnet. Several servers on same subnet. This doesn't seem to matter: For example: Server A on different subnet as backup server Server B on same subnet as backup server Monday Server A backs up 2 GB in 20 minutes, Server B backs up 2 GB in 2 hours Tuesday Server A backs up 2 GB in 1hr 45 min Server B backs up 2 GB in 30 mins In both cases the number of files and amount backed up are approx. the same. thanks, Link to comment Share on other sites More sharing options...
