Assertion error and logging

[misleb]

Hi,

 

I'm running Retrospect 7 and somewhere in the middle of my first backup to disk I got an "assertion error in somefile.cpp." I let it send a report to Dantz. Unfortunately I didn't write down the specific error in the dialog box because it said it would log the error to a .utx file. I cannot find any utx files anywhere on the system. In fact, I can't find any logs at all for the backup or the error. Under the History for the job it shows "Errors, Warnings: 0,0", "Performance 0.0", and "Elapsed: 0:00:00". Also, the "Error..." and "Log..." buttons are greyed out. The only thing is an entry under the "Events" tab showing "Execution terminated unexpectedly, possibly due to a power failure."

 

I know the backup wrote about 50GB to the destination disk. And I can see about half of the volumes in the set are available for a restore. Why no logs? How can I find out what happened? One thing I really want to know is the performance of the individual backup clients.

 

BTW, I'm running Retrospect server on Win 2k SP4. Backup clients are OS X, Linux, and Netware. All agents are up to date.

 

Thanks,

Update:

 

I got the error again.

 

"Assertion failure at nwv_rem.cpp-294"

 

This was during a backup of a Netware server. About 25GB into the backup.

Hi

 

I'm not sure what is happening here but we should cover some basics first.

 

Do smaller backups complete without error? For instance, if you back up a 1GB folder will the backup run to completion?

 

Have you tried rebooting the backup server and stopping/restarting the client server on the Netware machine? Rebooting both machines would be OK too.

 

What version of Netware is the client running?

 

Thanks

Nate

A smaller backup of just the SYS volume one two different Netware servers works. That is about 2.7GB each. I did restart the agent and the backup server. Unfortunately rebooting the Netware server isn't a great idea. I imagine it is possible that there is some corruption on the one particular Netware volume that it fails on. The problem is that, without logs, I cannot tell if it is always failling on the same file or directory. The error popup obscures the activity monitor and I can't just drag it out of the way because the window below won't redraw.

 

When I get a chance, I will run a repair on the larger volume which failed to backup. I'll make sure there is no FS corruption which may cause funky data to be sent to the Retrospect server.

Hi

 

Agreed - rebooting the netware server does not sound like fun.

 

Please let us know if the problems continue.

 

Thanks

Ok, Netware server volumes rebuilt. Server has been rebooted. I still get the Assertion failure and it seems to happen on one particular file. It it a large (28MB) tiff file. The file seems to be valid. I mean, I can view it fine.

 

This is Netware 6.0 SP5, BTW.

 

Any ideas? I'd really like to solve this rather that just excude the file from backup.

Is there some place I can get support for this? Unfortunately I am not a paying customer. I am just running a trial copy. But this issue pretty much determines whether or not Retrospect will work for us. I need to reliably backup our Netware servers. I can't just exclude each file when it causes Retrospect to crash.

 

I have now encountered another file that causes Retrospect to crash with the same assertion failure.

Hi

 

 

 

We will be happy to help.

 

 

 

Please send me a copy of the assert_log.utx file and a Windows system infomation report (text format) for the backup server. The assert log is located at c:\documents and settings\all users\application data\Retrospect on the backup server.

 

 

 

Please also confirm that you have these file versions installed on the netware server:

 

# eDirectory 8.7.3 and above

 

# Smdr 6.54a

 

# Smsut 1.01

 

# TSAFS 6.50.11

 

# Dsbk 10510.81.05

 

# Backupcr 10510.81.05

 

# Libcdebg.nlm 1.00.00
