retrospect stops backup without error


Recommended Posts

using 6.1 workgroup on a 10.4.11 server.

 

when i starting a backup retrospect backup a volume - after some files it stops. and hang on a single file.

no error. if i stop the backup it diplays "stopping by user" but nothing happens. i have to kill the app.

next try on an other volume happens the same. i see no reason why it hangs. no report in the protkollfile.

 

the kind of this files cant be the reason, cause with the old version 5.0 everthing goes without any problems.

 

what can i do?

 

thx for help, jürgen

thx,

i try different volumes. each volume stops on a specific file, but they have nothing in common.

i moved one "hanging" file to another place, start the backup, and then stops exactly on the next

file in the line. (the first file was an .eps the next was a .tif) the filetype doesnt matter - right?

 

i try differrent prevs: with kompression, without, with file-check and without - allways the same.

 

first i use the 6.1.126 version, yesterday i updated to the .138, but happens the same.

 

the backup device is an hp_dat-drive scsi / dds-3. the hardware konfiguration is untouched since

long time - and with the 5.0 version i have no problems.

be shure, i work with retrospect long long time - but never have such problems

(never change a running system...)

now i become a little bit nervous, cause 5 days without backup...

 

thx, jürgen

jürgen,

 

Just as a test to identify whether the issue is with the destination device / HBA, etc., could you try backing up to a file backup set to see if you get the hang in the same place? If you have a general idea where the problematic files are, you could even define a Retrospect subvolume as the source to decrease your testing time.

 

That would help isolate whether the problem is with Retospect, the RDU, the HBA, the tape drive, etc.

 

Also, could you be a bit more specific about your configuration that worked with Retrospect 5.0 as compared to your configuration now? (i.e., what was the Mac OS under Retrospect 5.0? what was the hardware under Retrospect 5.0? etc.) And what RDU version are you running now, as compared to the RDU before?

i try this. i have to backup 7 different subvolumes. i try it with smaller and bigger volumes, that makes no difference.

two volumes going complete.

 

the old configuration was: server 10.2.8 g4/400/512mb ram, retrospect 5.0.238, clients 10.2.8 - 10.4.11

now: server 10.4.11 g4/400/2gb ram, retrospect 6.1.138, clients 10.4.11, retrospect client ...130

the dat-drive is untouched

Yes, the DAT drive may be untouched, but the operating system has gone from 10.2.8 to 10.4.11. There is a vast difference in the underlying structure of those operating systems, which requires updating the DAT firmware, the firmware on the HBA, the driver, etc. Some HBA cards are no longer supported after Mac OS 10.3 (e.g., Adaptec), and this could be causing the problem.

 

Both Dave and I have requested information about the HBA, its firmware, its driver, and the RBU that you are using. This is critical information because they would NECESSARILY have to be updated with the OS update.

 

Because you refuse to provide this information despite multiple requests, I'm giving up on trying to help. Good luck.

what is RBU?

 


Sorry for the typo in my post this morning. It's "RDU", as I indicated before, which stands for Retrospect Driver Update. The RDU version is printed in the Retrospect logs each time Retrospect launches, and that information is also available by selecting Retrospect in the Finder and doing a "Get Info" (command I).

 

The RDU version history is here, with links to downloads of all versions:

http://kb.dantz.com/article.asp?article=7886&p=2

 

Bug fixes and driver updates are released by way of the RDU, wihch goes in the same folder as the Retrospect application.

Ok, then that's your problem. Adaptec dropped support for Mac OS X as of 10.3.9, no support for 10.4.x. Their drivers don't work with 10.4.x and beyond. You need a new HBA. I suggest an ATTO UL4D, which is the PCI Express adapter that everyone recommends. We have one in our Xserve, works great. If you get an Intel Xserve with PCIe, then get an ATTO UL5D or UL5D Low Profile.

hi russ, that sound not so good.

 

i will check this problem. therefor i take an external fw-hd and try to backup on this device.

stays the problem, then couldnt be the scsi-card the reason.

what do you think?

 

 

question:

go that scsi-card with my g4/agp with normal pci-slots? cause that machine have no pci-express slots.

The problem is not the slots, it's the fact that Adaptec stopped supporting Mac OS X, and does not have drivers that work with Mac OS 10.4.x or 10.5.x. The ATTO UL4D card will work in normal PCI slots - it's backwards compatible. However, you may be able to find an ATTO UL3D card, which is "normal" PCI.

 

I agree with your assessment to try the backup with an external Firewire HD. However, that won't fix the fact that Adaptec does not have a driver for Mac OS 10.4.x or 10.5.x. Your Adaptec card will work fine on the old 10.2 or 10.3 Mac OS. That's why it used to work and no longer works.

 

FYI, here is an old notice from Adaptec when they abandoned the Macintosh platform several years ago:

Adaptec notice - abandoning Macintosh platform

hi russ,

 

just i finished my complete backup, almost 90 gb to the fw-hd-drive. the speed is nothing to compare with the dat-drive.

and the best: without any error. :-)

i know this is not the best solution. but this time my onliest way until i bought the atto-card.

 

thank you for your support and your patience with me.

nice weekend

 

jürgen
