When our Veeam backups run out of disk space on our Server 2016 REFS volume, the server stops allowing logins via RDP and on the console gets stuck at this message
Setting up personalized settings for web platform customizations
I can get to task manager on the console and see some services stopping and starting, if I try to logout it gets stuck, only option is to force the server off.
This message appears in the logs around the time after the backup runs and fulls the disk:
tcp/ip failed to establish an outgoing connection - and it looks like lots of Veeam event logs message about File is locked by 1 processes
I upgraded the server to the March cumulative update mentioned above but it still had the same problem, maybe it will be fixed in the April update.
We are only using reverse incremental backups but it does seem to be using this Fast cloning Dedupe thing as the total of the backups is more than the total disk size
Does anyone know if you can disable Veeam from using this new REFS Fast cloning feature without rolling back to NTFS??
