lesccseh Posted May 15, 2008 Report Share Posted May 15, 2008 a backup of a pc on our network that i had successfully run numerous times is now exhibiting unusual behavior. at some point during the backup, the transfer rate drops to a crawl. stranger still, if on the server that the backup device is attached to, i start doing something else (eg. launch an unrelated app), the transfer rate might recover, either for the rest of the backup or for a while before it slows down again. any ideas? note that while i am running the latest version, i have not been able to determine whether there is a way to update the client in case that needs updating. server: windows xp with all updates retrospect professional 7.5.508 (driver update and hot fix 7.5.14.102) iomega rev 35gb usb client pc: windows xp with all updates Quote Link to comment Share on other sites More sharing options...
Mayoff Posted May 15, 2008 Report Share Posted May 15, 2008 Try turning off XP system restore. It can slow things down. Virus scanning software can also slow you down. Quote Link to comment Share on other sites More sharing options...
lesccseh Posted May 15, 2008 Author Report Share Posted May 15, 2008 Thanks, Robin. Just to clarify, "slow down" might be misleading. By slow down I mean to the point where it is barely operating at all (eg. would take 1 day or longer at that rate to fill a 35gb cartridge), until I do something on the server to "wake it up". And this is new behavior. The two suggestions you offered .. is that on the server, workstation, or both? I am hyper about turning off virus scanning, but will try it at least to help diagnose the problem. Quote Link to comment Share on other sites More sharing options...
Mayoff Posted May 15, 2008 Report Share Posted May 15, 2008 I would try the backup computer first, then virus scanning on the client os see what happens. Quote Link to comment Share on other sites More sharing options...
lesccseh Posted May 15, 2008 Author Report Share Posted May 15, 2008 thanks, i will try that. does the software that runs on the client automatically get updated, or do i have to do that manually somehow? les Quote Link to comment Share on other sites More sharing options...
MRIS Posted May 16, 2008 Report Share Posted May 16, 2008 re: iomega rev 35gb usb use device manager, change the view to see devices by connection then see the name of the USB controller it is attached to. If the word ENHANCED doesn't appear in its name then it's likely it has synced at USB 1.1 speeds rather than USB 2.0 speeds which would explain perfectly what you are seeing. USB 2.0 devices connected to USB 2.0 host controllers regularly fall-back to USB 1.1 and only using device manager can you see whether it is using USB 2.0 or USB 1.1 speeds. Try disconnecting then reconnecting the USB drive until it connects via an ENHANCED USB host controller.
