Ntfs error 55 with server 2012r2 backup

[arjen]

Hello,

In the event viewer/system log at the veeamproxy we have the following error when server 2012r2 is performing a backup:
- Source:Ntfs - Event ID:55 - The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume E:. .......(and same with F.)

Everything seems to be ok. I can backup and restore without a problem but events are generated with every server 2012 r2
We use Veeam Back&Rep version 6.5.0.144 on a server 2008 R2.

Greetings Arjen

Arjen, backing up VMs running Windows Server 2012 R2 or Windows 8.1 is not supported even in the latest Veeam B&R v7. This support will be implemented in the patch 2 planned to be released later in November.
