Virtual Edition - Failed to read data from the disk

Thread needs solution

We recently started using Acronis Backup & Recover 11 Virtual Edition and when we try and backup our SBS 2011 server running on our ESXi 5.0 host we get the following error.

*************************************
Simple Backup
Backing up virtual machine
Failed to read data from the disk.

retry, ignore, ignore all, cancel
**************************************

We have tried:
- disabling or using different VSS options
- backing up only one of the two Virtual disks that the virtual machine uses
- Other virtual machines work fine (linux, windows 2008 r2)

After the backup the vmware host says that the virtual machine needs consolidation but it failed. When I try to manually consolidate the virtual machine it says "Unable to Access file since it is locked."

I have attached a copy of the failed backup log.

Regards

Matt

Hello Samsons Support,

Thank you for the log provided.

According to it the problem is related to the host actually.
VMware_VDDK: [NFC ERROR] NfcFssrvrRecv: failed with code = 9
We receive this error from VMware APIS, and cannot proceed with the backup because of it.

We would advise you to troubleshoot the issues with host according to these instructions.

Should you need anything else or have any further questions - feel free to contact us at your earliest convenience, we will be happy to help you!

Thank you.
