black7 Posted March 30, 2002 Report Share Posted March 30, 2002 I just upgraded to 5.0 (5.0.201) and have found the compare portion of the backup totally unacceptable, while in OS X. I average about 120mb/min during the write, and 5mb/min on the compare. I'm having to cancel the compare on all my backups now- a major bummer. I did not have this problem with the beta. Is anyone else seeing this? System Info: Dual 1ghz g4, 1024 mb ram Lacie DDS-4, Adaptec 29160 SCSI PCI Link to comment Share on other sites More sharing options...
EEvanson Posted March 30, 2002 Report Share Posted March 30, 2002 In reply to: Is anyone else seeing this? Yes, I am. On the (ahem) plus side, Retrospect usually crashes on me before I get to the verification stage, saving me the trouble of cancelling it.

black7 Posted March 30, 2002 Author Report Share Posted March 30, 2002 A little more info on what I am seeing- During the compare, the tape/drive is cycling from Comparing... to Rewinding... to Locating... every few seconds, over and over. It appears to never get a good chunk of data from the drive to compare with, so the speed is down around 5mb/min. I see this behavior when trying to backup both the systems internal drive, and also against a 60gb firewire lacie drive. Link to comment Share on other sites More sharing options...
nycdude Posted April 1, 2002 Report Share Posted April 1, 2002 If you check your Log you'll notice that it's not just bad compare times, but the indication that the information on the tape is useless (see here:) - 3/31/2002 7:04:37 PM: Copying OSX 733… 3/31/2002 7:31:40 PM: Comparing OSX 733… Bad backup set header found (0x69742e66 at 45,829).

Remaining: 76066 files, 2.6 GB Completed: 671 files, 55.4 MB Performance: 106.6 MB/minute (111.8 copy, 32.2 compare) My copy time was dogged when the screen saver kicked in, and had seen around 163MB. I'd like to see Retrospect block that kind of activity in the future. Anyway, the SCSI card you're using isn't qualified. From what I've read taking a Wide 68-pin device down to a 50-pin Interface seems to be the problem. Anyone tried a terminating adapter for this? I'm not sure what else to try. I've got the current Adaptec 39160 1.1.0 drivers installed, and it is the only device on the chain. It works fine with Retrospect 4.3 in OS 9.2.2. I'm running OS 10.1.3 on a G4/733 with 640MB RAM, an Adaptec 39160 SCSI card and a Sony SDT-11000 DDS-4 drive. The setup is "qualified" by Dantz and there is no mention of this kind of problem anywhere but the Forums. My experimentation seems to prove that the problem is that the data written to tape is bad. If I write a tape in OS 9, it will verify and restore with expected performance in OS X. If I write a tape in OS X it will appear to write correctly but not verify, and the tape will not restore in OS 9. Any insight would be appreciated!

Threedrules Posted April 1, 2002 Report Share Posted April 1, 2002 I have the same Problem. Everytime when the Retrospect (workgroup edition) is running the file compare, the programm hangs up after a short time. Any solution to this problem would be appreciated. Software: mac os x server v10.1.2 Hardware: Adaptec 29160 (Driver V. 1.1), HP Surestore DAT 40. Link to comment Share on other sites More sharing options...
IrenaS Posted April 3, 2002 Report Share Posted April 3, 2002 Further testing with the Adaptec 29160 card has shown that it does not offer consistent reliability when used with Mac OS X. Thus, Dantz is removing this card from our list of SCSI host adapter cards that function reliably with Mac OS X. Our online documentation has been updated to reflect this incompatibility. We will continue working towards supporting this card with Retrospect under OS X, but this configuration is currently not supported.
