Re: Backup of Celerra CIFS with Avamar

Jump to solution

To confirm, here's the service path -> "C:\Program Files\avs\bin\avagent.exe" /ServiceStart "--logfile=C:\Program Files\avs\var\avagent.log"

It was running under "Local System" and I changed it to run with a Domain Admin account.

Stopped and restarted service. Re ran backup, still no go.

I did the same thing as you did, but I also went to options, selected Windows File System, scrolled down and selected "Traverse fixed-disk and remote network mounts". Then I run the backup, and the files get backed up. One error I do see is Error=1314 (code 1314: A required privilege is not held by the client) which means that the ACLs for the file aren't backed up.

Glad this worked.  Im sorry I missed that step.  I was actually testing the process.

ACLs will not get backed up.  They can't be backed up because you are pulling from a remote source.  Another downside to using UNC paths for backing up with Avamar is each time a backup job is initiated, all files will be pulled across the network to the client to be checked and the deduplicated.  Don't expect the time to reduce for the backups either.  To get a proper backup (ACLs, files, etc) and to reduce the actual time to run a backup, you will need an Avamar Accelerator Node.  the node only supports specific NAS devices (EMC Celerra and NetApp for sure, plus some others).

I believe I did all of the above. But still don't get this running.

I run the agent with a domain admin and not local system account. This user has all right on the cifs share. Restart the service and started anothe backup.

Also checked the traverse local and mapped drives

If you log into the system where you're backing up the share as the domain admin, are you able to ping cifs1811 by short name? Can you browse to \\cifs1811\software manually (i.e. type the UNC path into a Run box or the search bar and it opens correctly)?

If not, does this test work using the FQDN instead of the short name?

Also, I would strongly recommend backing up the data at the source if possible. Backing up a CIFS share is supported does work but you will likely have better results if you back it up at the source.

Edit: Support for backing up CIFS shares from a NAS device is best effort only.

Re: Backup of Celerra CIFS with Avamar

Hi guys!


I've been through with same problem with a customer here in Brazil...he followed all yours tips but in the last part " Now create a group, assign it a dataset and make the client part of that group.”

Which client should I add to the group? Should I mount that CIFS server in a client that is in the VCenter and then add that client to the group?

Hope you can help me!

Cheers!

Re: Backup of Celerra CIFS with Avamar

You could do this and it might work happily ever after.. but please do be aware that Engineering have stated that backing up or restoring CIFS or NFS shares via a regular Avamar client isn't actually supported functionality

Reference:

KB 174435 - Avamar and supportability for CIFS / NFS mapped network shares



Update: I just noticed the second page of replies and I see Ian already warned about the implications for supportability
