VMware backups fail with exit code 20

VMware backups fail with exit code 20

VMware backups fail with exit code 20

I'm backing up a set of Linux VM's using the query builder. There's a dozen Linux VM's on this one datastore I have in which all but one of them back up successfully. It's exiting out with a status code 20, invalid command parameter.

Client will backup successfully from within the VM but will not from the datastore using VMware policy type.

It's OS is: 2.6.18-348.6.1.el5 #1 SMP Fri Apr 26 09:21:26 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

My master and media servers are all Netbackup v. on Windows 2008.

I verified all my zoning is correct and all my media server which are the VMware backup hosts have access to the datastores.

The backup will do the snapshot and then when it get's to the point where it starts the backup job doesn't seem to start streaming/writing any data.

It then errors out and fails with exit code 20.

Any ideas? Thanks!

RE: VMware backups fail with exit code 20

How much free space on the data store? What version of vmware?
Have you tried moving it to another datastore and then backing up?
