Maser Posted February 8, 2006 Report Share Posted February 8, 2006 So I upgraded a Windows client from 7.0 to 7.5 (backing up to my Retrospect 6.1 server.) Granted, this is an experiment with *one* computer, but the backup speed -- on a switched 100Base-T network -- to that client dropped from in the 250M/Min range to 15M/min. this is on XP SP2, etc... Am I missing something here? Quote Link to comment Share on other sites More sharing options...
Maser Posted February 9, 2006 Author Report Share Posted February 9, 2006 So, I reproduced this on *many other PCs*. EMC, there's a problem here! this is with using Retrospect 6.1 on the mac. had a client (XP SP2 all patches). Had the last 7.0.107 client. Backed this computer up to one tape. Ran at 246.8M. upgraded this client to the 7.5 release. Restarted the computer. Backed the computer up a 2nd time: Ran at 17M/min!!! Uninstalled the client. Reinstalled 7.5. Ran the backup again: still ran in the 15-20M/min range. Turned the firewall *off*: no difference. Slow Uninstalled 7.5. Put 7.0.107 back on. Rebooted and ran backup: back to the high 200M/min range. The odd thing -- the actual *scan* of the computer is about exactly the same between 7.0 and 7.5 client. Backup speed is extremely different, though. - Steve Quote Link to comment Share on other sites More sharing options...
RonaldL Posted February 9, 2006 Report Share Posted February 9, 2006 I'll give this a try and report back. How much data are you backing up? You note that you're backing up to tape, does a file backup set show the same performance differences? Quote Link to comment Share on other sites More sharing options...
Maser Posted February 9, 2006 Author Report Share Posted February 9, 2006 I was only trying (as a test) to backup about 300-500M (backed up the same set of data to different tapes, too.) Doing a file backup doesn't interest me (as it would take a lot of time to set this up.) I should also mention that we have a couple of Linux clients. We updated those to the 7.5 Linux client and there was *no* performance degradation there. it's specific to the Windows client. I'm hopeful (?) that you can reproduce this.

RonaldL Posted February 9, 2006 Report Share Posted February 9, 2006 I am seeing mixed results with different machines. In one test, the speeds dropped from 200-250 down to ~10 megs/min after the update. In another test, the speeds actually increased from ~70 to ~250-300 megs/min. We'll have to do a little more investigating on this issue. Quote Link to comment Share on other sites More sharing options...
Maser Posted February 10, 2006 Author Report Share Posted February 10, 2006 speed increase would be good. We're only seeing the consistent decrease in speed. disabled the "on-access" anti-virus Software (VirusScan) -- that made no difference, either.

RonaldL Posted February 13, 2006 Report Share Posted February 13, 2006 I've logged a bug for this. If you are using 6.1 for Mac, our recommendation is to stick with the 7.0.107 client for the time being. Quote Link to comment Share on other sites More sharing options...
Maser Posted February 15, 2006 Author Report Share Posted February 15, 2006 Thanks! Had another user in another department duplicate my findings. If they let you know what's up, please post! Quote Link to comment Share on other sites More sharing options...
bwodka Posted February 16, 2006 Report Share Posted February 16, 2006 I am going through the same issue. I am running 7.5.251 multi server on a Win 2oo3 box with all the updated clients. Mac and PC. This is killing me. I called tech support and nothing worked. Please help out here. SLOOOOOW back up. I can't get one backup script done over night.

urza311 Posted February 17, 2006 Report Share Posted February 17, 2006 I can also confirm the same problem. I've got a Mac OS X 10.3.9 station with Workgroup 6.1.126 and driver update 6.1.3.101. It backs up about 3.7G worth of data across 16 different clients (1 OS 9, 2 OS X, 13 Win XP Pro SP2). All my clients were 7.0.107 and running fine. I upgraded one station to client 7.5.111 as a test. Of the Win XP clients that had a similar amount of data (300-1000M), here are the performance logs for them (running client 7.0.107): Performance: 342.3 MB/minute (253.9 copy, 524.8 compare) Performance: 421.0 MB/minute (343.4 copy, 543.8 compare) Performance: 283.4 MB/minute (215.6 copy, 413.3 compare) Performance: 296.8 MB/minute (208.9 copy, 512.4 compare) Performance: 447.4 MB/minute (341.4 copy, 649.0 compare) Performance: 286.8 MB/minute (352.0 copy, 242.0 compare) Performance: 276.5 MB/minute (198.9 copy, 453.1 compare) Compare that to this client now running 7.5.111: Performance: 23.9 MB/minute (12.3 copy, 404.0 compare) And here are the last three logs for that same client when it was running 7.0.107: Performance: 267.3 MB/minute (216.2 copy, 350.1 compare) Performance: 274.8 MB/minute (222.8 copy, 358.5 compare) Performance: 271.6 MB/minute (220.7 copy, 353.1 compare) The hit is almost entirely in the copy portion of the backup; the read/compare works just fine. One more note: we have a single Retrospect Professional 7.5.251 station (Win XP Pro SP2) that had been running 7.0.326, and I just upgraded that. This station also backs up another Win XP Pro SP2 station with about 400M data, and that client had been running 7.0.107. I upgraded it to 7.5.111 and it's running fine. Here's both a before and after log for that client: before: Performance: 573.4 MB/minute (389.7 copy, 1084.4 compare) after: Performance: 586.9 MB/minute (374.2 copy, 1359.2 compare) It seems the problem only occurs with the 7.5.111 client if you're backing up remotely to a Mac insead of a Windows station.

bwodka Posted February 20, 2006 Report Share Posted February 20, 2006 any update on this? Quote Link to comment Share on other sites More sharing options...
raw181 Posted February 20, 2006 Report Share Posted February 20, 2006 I downgraded back to Both client and server back to 7.0, and I'm good now. Quote Link to comment Share on other sites More sharing options...
RonaldL Posted March 1, 2006 Report Share Posted March 1, 2006 The speed issue will be fixed in the next release of the client. If you are experiencing slow backup speeds using the 7.5 client, please use the 7.0.109 client from http://www.emcinsignia.com/supportupdates/updates/retrospect/archive/.

raw181 Posted March 2, 2006 Report Share Posted March 2, 2006 Thanks. Any ETA on the new client? TIA. Quote Link to comment Share on other sites More sharing options...
RonaldL Posted March 2, 2006 Report Share Posted March 2, 2006 There is no set date for the new client. I will post an update to this thread as soon as it's released. Quote Link to comment Share on other sites More sharing options...
RonaldL Posted April 27, 2006 Report Share Posted April 27, 2006 A new client was just released which should address the slow client backup issue. Download and install the 7.5.116 client installer from the updates page: http://www.emcinsignia.com/supportupdates/updates/ Please report any issues that you run into.

Maser Posted May 5, 2006 Author Report Share Posted May 5, 2006 Bump... With the release of the 5/4/06 dated Windows 7.5.116 client -- has this problem been resolved now? or should we just use the newer 7.0.112 client? Quote Link to comment Share on other sites More sharing options...
Maser Posted May 8, 2006 Author Report Share Posted May 8, 2006 Well, since nobody answered... I installed 7.5.116 on a PC that had it's backup speed cut by 90% with the original 7.5 client. Speeds with 7.5.116 were comparable to the 7.0 client. Still -- it'd be nice to get some official work from this if EMC/Dantz thinks the problem is resolved with this version of the client before we push it out...

RonaldL Posted May 8, 2006 Report Share Posted May 8, 2006 Yes this build should fix the speed issues when backing up from a Mac backup server. Keep in mind that from the Mac end, there's no benefit with going to the 7.5 client, but now there shouldn't be any decrease in performance either.
