I have a problem related to Windows Server Backup in Windows Server 2012.
In my scenario I have two physical servers (host VM's in Hyper-V), both configured to perform daily full backup of the server (VSS Full Backup). The schedule was created within the console of Windows Server Backup is not used any scripts for running backups.
For storage I'm using 3TB external drives that have been formatted automatically by the tool Windows Server Backup.
These two host's servers were with a history of XX day backup, but while checking this morning, all my history vanished, stating only the last executed copy of the previous night.
In a matter of disk space, both hd's have over 60% free space, in which my backup's use only 1TB of space.
The first case occurred in my server host01, and after a week the same thing happened with my server host02.
The space for shadow copies (Volume Shadow Copy) on my backup disk was first set to Maximum size "No Limit". Configured in the same backup disk is a limit to the storage space of the volume shadow copy in 25% (715264MB = 698.5 Gb), with the total space of the recognized HD 2794GB.
I have the same configuration on other servers with Windows Server 2008 and they did not have this problem, always maintaining a long history of backing up and deleting the oldest ones as needed.
I do not see a specific reason for the tool to be deleting the entire backup history on this server, owning more than 60% of free disk space.
Has anyone experienced this? What can be happening?
