Data Recovery backup job fails with error -3902

Whenever I run the Data Recovery backup job it creats the VM snapshop and then immediately removes it and fails with the following errors:

6/2/2009 9:11:24 PM: Normal backup using Backup Job 1

6/2/2009 9:13:22 PM: Failed to create snapshot for VM1, error -3902 ( file access error)

6/2/2009 9:13:22 PM: Task incomplete

This happens for any VM.

Does anyone have an idea why it fails?

Thanks in advance,

Roy

Adjusting the \etc\hosts file did not fix this for me.

I have 1.3 TB of space available on the network share and the VM I am trying to backup is only 40 GB.

I haven't rebooted the VDR appliance, but I didn't think I would need to. I will try that and if it makes a difference, I will let you know.

In the meantime....does anyone have any other ideas why this -3902 file access error (during snapshot) would be failing? I can successfully create snapshots manually even with the Quiese Guest Filesystem checked.

Jim

Update:

I rebooted the appliance and now it all works....no idea why as I could resolve the hostnames of the vCenter and all the ESX hosts prior to the reboot. I could ping them via IP or name and it all worked.

However, I don't argue with success...so I am working now.

I am having the same -3902 error. And after I rebooted the VDR, it works fine. It is the third time that I need to reboot the VA. I don't know what is causing this since I don't have any configuration change.

@Fobe and Jim Nickel

I'm a new poster here with the same problem. The "hosts" file fixed my problem as well, but I needed to restart the vDR appliance. When I did, all my backup jobs fired up.

Thx!

what happens if you go over 500GB in your 1 TB dedup store?

Note that VDR 1.1 is now available. This releaseeliminates reoccurring error -3902 after vCenter Server connection has been restored, so we highly recommend customers upgrading to this release. See my post in the forum for more information about this release.

Thanks.

I am having this issue on my appliances, and rebooting the appliances do nothing. I have tried /etc/hosts and that does nothing either. Anything else to try. I have gone the route of calling support and that is useless as they have you wipe your deduplication store most often as they call it "corrupted"

I would create a new discussion thread for your issue with as much detail as you can. List versions, what you have tried etc. Feel free to refer to this thread.
