aesmith Posted March 10, 2014 Report Share Posted March 10, 2014 This is the first weekend our offsite backups have run under the new version 9 of the Windows single server Retrospect. This is done via a 2 TB usb 3 connected hard disk. Generally this task has been completed easily between Friday night and Monday AM, but I come in today and see it is only about half done. Comparing the reported performance values I can see why. Here is some examples for the same three backups V8.5 = 1283/1808/1297 V9.0 = 903/759/751 You can see a huge difference in transfer speed. Nothing else has changed in the system other that upgrading the version of retrospect. Any ideas why this would be the case? Allan Quote Link to comment Share on other sites More sharing options...
aesmith Posted March 10, 2014 Author Report Share Posted March 10, 2014 Maybe this will help shed some light on it as well.

aesmith Posted March 10, 2014 Author Report Share Posted March 10, 2014 I have been watching it do this "offsite" backup to usb HD and it seems the real slowness is that at the end of each round of backup (each backup set often has 7 sub parts) it get stuck spinning its wheels. It goes through repeated rounds of Matching/updating catalog files but not progressing like it used to. Quote Link to comment Share on other sites More sharing options...
bdunagan Posted March 11, 2014 Report Share Posted March 11, 2014 That is a dramatic drop in performance. Could you contact our support team and attach your operations log (as a zip)? Then we can start trying to reproduce the issue ourselves. Quote Link to comment Share on other sites More sharing options...
