VRTRalus daemon stopping on Linux machine/backup fails

[dfisicaro]

We seem to be having a problem with the "VRTRalus daemon" on one of our linux servers that is trying to get backed up by our BackupExec 12.5 Windows 2008 server.

It looks like the daeomon actually stops running either before the backup starts or when it tries to access it.

All of our other Linux servers work fine but for some reason we are getting the following message in the daily backup job when it tries to connect to this server. (The other Linux servers are basically identical to this one)

V-79-57344-3844 - The media server was unable to connect to the Remote Agent on machine hudson64.kc.... The media server will use the local agent to try to complete the operation. Access is denied to Remote Agent. Check the login account for the specified device.

I have tested doing a backup of some files as a test backup job and it works fine. But for some reason when its part of the "daily incremental" or "full backup" jobs in the evenings it "fails".

I've tried debugging the problem by outputing the error to a log file but can't really notice anything that's causing it to stop.

Any help or tips would be appreciated.

Thanks,

Daniel

Daniel,

What Linux distro are you running?  Is it a supported distro for 12.5?  I'm trying to get a similar setup going on Ubuntu 9.10 - the agent installes fine (and in my case does not seem to hang or stop), but I can't get the BE server to authenticate the agent so I can browse the shares in a selection list - Be simply won't connect with root account creds.  I'm current on patches for 12.5, but have not installed updates for the agent yet (which may be part of the issue) - I wonder if there was some hotfix on the BE side that requires a patch on the Ralus agent side for proper communication.  PRevious hotfixes on the server end have broken linkages between Windows and DLO agents for me before until the agents were updated...

We are running Centos 5.3 on all of our servers. Which is basically Redhat Enterprise 5.

It works fine on all of the others servers.

I'll check if its in the supported though.

V-79-57344-65072 - The connection to target system has been lost. Backup set canceled.

This is the error that appears.

It seems to actually start backing up fine and then suddenly crashes at some stage.

I've run this command:

/opt/VRTSralus/bin/beremote --log-file-auto

Then started the backup job and get this messaged when the backup fails with the above error:

Any suggestions?

Dan,

Could it be a physical issue (networking, power-management, etc) or are you pretty sure it's software side?  Can you still connect to the Linux server and browse the folder list (I'm assuming yes as you were able to create the backup in the first place).  Are you backing up directly to tape or to a B2D setup?  If not the latter, try that out - I'm thinking some of your settings in your backup policy in the advanced tab may need looking at - I haven't gotten as far as you yet, but with Linux it's more important to make sure the 'follow mount point' and 'symbolic link' settings be correct as well...

Have you tried updating the RALUS agent at all to match your BE updates for 12.5?  I have done this on my Ubuntu box, though it has not helped me yet:

[dfisicaro]

Thanks for your replys. I'll have a read of the links you sent.

The Ralus agent stops/crashes at a similar stage in the backup job.
I can browse all the files fine when I restart the agent though and run the job again. Could it be related to it trying to backup a specific folder on the Linux server?

We are backing up directly to Tape.

I've tried turning off "Verify" when running a test job on that box but can try switching off other options.

The thing is all of our other Linux servers are running pretty much the same Linux distribution and Ralus agent and not having a problem. Just this one which is weird.

[dfisicaro]

Ok.

It looks I have had success on that linux box overnight.

What I did was install the following RALUS update:

http://seer.entsupport.symantec.com/docs/328485.htm

And then tested the backup and let it run last night and the agent hasn't crashed.

Will see how it goes.

Thanks for your help.
