miketrose Posted September 1, 2004 Report Share Posted September 1, 2004 Here's an ongoing and very frustrating problem: Our backup server (Dual G4 1.25, 1.75 GB RAM, OS X 10.3.5, Retrospect 6.0.193 w/ current 5.2 RDU, Cybernetics AIT-3 30 tape loader with current firmware) has a performance problem when backing up Mac OS X clients. OS 9 and Windows clients go smoothly -- scan, compare, and then within 15-30 seconds the backup begins. The average backup takes about 7-8 minutes. OS X clients, on the other hand, cause Retrospect to stall for 10-30 MINUTES between the end of the comparison pass and the start of actual data transfer. It sits on the "preparing to execute" dialog with the activity cursor going; click anywhere in Retrospect and get the rainbow cursor. Retrospect is so completely locked in this mode that you can't even stop the backup. Meanwhile, CPU usage is idling near zero. These stalls are causing us to overrun our backup windows and miss lots of client backups. Has anyone else seen any similar behavior? I'm just about to pick up everything and move it over to the PC, but I would hate to waste all the money spent on Mac 6.0 licenses and clients... --Mike Link to comment Share on other sites More sharing options...
miketrose Posted December 6, 2004 Author Report Share Posted December 6, 2004 For what it's worth, the PC version of Retrospect has the same issue... up to 30 minutes 'idle time' when backing up Mac OS X clients. Link to comment Share on other sites More sharing options...
natew Posted December 8, 2004 Report Share Posted December 8, 2004 Hi 6.0.204 is the most current Mac release. You should try installing that for starters. How often does the backup server machine get rebooted? Does doing so make any difference with this problem? Thanks nate Link to comment Share on other sites More sharing options...
