J.T. Fey Posted March 21, 2005 Report Share Posted March 21, 2005 I have Retrospect 6 installed on an Apple Xserve (dual 1.33 GHZ processors). I also back up a second Xserve (dual 1.0 GHZ processors) over the network (Retrospect Client). Both servers are running 10.2.8. The backup device I'm using is a Exabyte VXA-2 1U 1x10 packetloader. This combination had worked extremely well until March 11 when our network went down due to a switch failure. Now, the host server backs up at a speed of about 330 megabytes a minute. When Retrospect moves to the server running Retrospect Client, the speed drops to 10 megabytes a minute. Because of this, I've removed the second server from the backup script until I can solve this problem. Any ideas what might cause this? Thanks.

jbeek Posted March 22, 2005 Report Share Posted March 22, 2005 Have you looked at the switch to see if the lights are "blinking" a network conflict? I think I have seem this caused by a Duplex mismatch. Maybe the switch is forcing one of the Xserve's to be half-duplex and the other to be full-duplex? Good Luck, Justin Link to comment Share on other sites More sharing options...
J.T. Fey Posted March 22, 2005 Author Report Share Posted March 22, 2005 If this were true, wouldn't the users of this server see a dramatic slowdown in moving files? The lights don't show it (3Com Switch 4228), but the documentation says the lights wouldn't reveal that. I'm doing some checking on that. Thanks.

J.T. Fey Posted March 23, 2005 Author Report Share Posted March 23, 2005 The switch ports and server ports are all saying I'm getting gigabit flow. I'm wondering if this isn't an Appletalk issue. How does Retrospect find clients on the network? Link to comment Share on other sites More sharing options...
jbeek Posted March 24, 2005 Report Share Posted March 24, 2005 Did you find out if they are both full-duplex? Link to comment Share on other sites More sharing options...
CallMeDave Posted March 24, 2005 Report Share Posted March 24, 2005 Retrospect finds clients on the network via UDP. AppleTalk support was removed from the client software starting at version 5 (under both OS 9 and OS X). So it's not that. Since it worked originally and you made no changes to your Retrospect configurations (any that you've noted, at least) it's likey not a Retrospect configuration issue. So the question becomes, what else changed besides the network hardware? - Are all your addresses the same as before the new switch? - Are both XServes on the same subnet? - Have both maches been restarted? - Have you tried forgetting and then re-adding the Client?
