texesa Posted April 25, 2008 Report Share Posted April 25, 2008 Hi all, My backup performance over a gigabit networked has gone down over the last week. I was getting over 700MB a minute, now it's 400MB and it's taking twice as long to do it's backup. I'm backing up data over a gigabit network directly onto internal SATA300 hard disk I have restarted the affected servers it's backing but it's made no difference. I know there are quite a few factors involved but I just wondered if someone else has had this problem. Might have to re-install the retrospect clients Any advice would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Mayoff Posted April 25, 2008 Report Share Posted April 25, 2008 Do other computers backup quickly? What happens if you backup the backup server to the backup destination? What is the performance? Do you connect over the network with the Retrospect Client or with filesharing? Quote Link to comment Share on other sites More sharing options...
rhwalker Posted April 25, 2008 Report Share Posted April 25, 2008 You might have gotten to the point where your Retrospect catalog is big and/or the number of files being backed up is large, causing thrashing. Check to see if you have enough physical RAM on the Retrospect machine. Russ Quote Link to comment Share on other sites More sharing options...
mazur50 Posted June 1, 2008 Report Share Posted June 1, 2008 I have the same problem i am backing up to tape when I backup my mac server I am getting anywhere from 1500MB/m- 2100MB/m but with the same machine i back up a windows box I am getting only 300 or 400MB/M and they are all pluged in to the same Gigabit switch. That backup machine is Dell PowerEdge 2650 Xeon 2.8 with 2GB of ram running 7.5.508 Retrospect MulitServer When you look at the machine that is being copied I am only using .5-9% of the 1000mb/s nic. this is all going thru the retrospect client. I would like to get all my servers going at 1500MB/S plus thanks Mike Quote Link to comment Share on other sites More sharing options...
MRIS Posted June 1, 2008 Report Share Posted June 1, 2008 Try upgrading the NIC drivers in the slow machine. Sometimes the auto-negotiation of the link speed results in a 100Mbps link instead of 1000Mbps. Try hard-setting the speed to 1000Mbps instead of auto. If the auto-negotiation is setting it to 100Mbps, then maybe the cabling is underspec/faulty? Quote Link to comment Share on other sites More sharing options...
