I’ve just completed a migration from SBS 2003 to SBS 2011 for a customer and the final phase of this project was backup.
The new SBS 2011 was deployed using the free edition of VMware vSphere 5 Hypervisor (ESXi) so I was keen to try out the latest version of Veeam Backup and Recovery v6 with this.
I download Veeam Backup & Recovery v6 and set it up using my trial Key.
The product itself is a breeze to get installed and setup but I immediately ran into issues when trying to run my first backup.
The backup job would hang for around 15 – 20mins before throwing the following error
Failed to prepare guest for hot backup. Error: VSSControl: Failed to prepare guest for freeze, wait timeout 900 sec
Error: VSSControl: Failed to prepare guest for freeze, wait timeout 900 se
After a bit of digging I stumbled across an SBS post relating to SharePoint Foundation 2010 SP1 and the need to manually complete the SP1 process.
Failure to complete the process can prevent all backups from working which is what happened in my case.
See the following article for full details on how to resolve the issue.
