I'm on VMware ESXI 5.0.0 Update 1 and wanted to use the ghettoVCB script for backuping my VMs.

The dryrun went perfectly fine:

2012-10-24 11:47:46 -- info: ###### Final status: OK, only a dryrun. ######

But when I try to do an actual backup, I get the following message for every VM on my host:

2012-10-24 11:48:43 -- info: Initiate backup for Willert-Tools
2012-10-24 11:48:43 -- info: Creating Snapshot "ghettoVCB-snapshot-2012-10-24" for Willert-Tools

2012-10-24 11:48:47 -- info: ERROR: error in backing up of "/vmfs/volumes/datastore1/Willert-Tools/Willert-Tools_1.vmdk" for Willert-Tools

2012-10-24 11:48:47 -- info: ERROR: error in backing up of "/vmfs/volumes/datastore1/Willert-Tools/Willert-Tools.vmdk" for Willert-Tools

2012-10-24 11:48:50 -- info: Successfully compressed backup for Willert-Tools!

2012-10-24 11:48:50 -- info: Backup Duration: 7 Seconds
2012-10-24 11:48:50 -- info: ERROR: Unable to backup Willert-Tools due to error in VMDK backup!

What am I doing wrong? As I didn’t want to paste every configuration snippet from my configuration, please ask if you need more specific information.

The backup is supposed to be saved to a NFS share which is correctly mounted on my ESXi host.

Thanks for your help :-).

the most I can suggest by seeing the output is:

1) Are you sure the path to your NFS mount or datastore is correct in the ghettoVCB configs? Double check all NFS configs for ghettoVCB.


2) Is your NFS share accepting anonymous access and granting read/write permissions?

Judging by the output, the script was able to create the snapshot but then 5 seconds later it said it could not back up the VMDK. My guess is this is a permissions issue on NFS mount. That, or lack of free space.
