We are experiencing resets of the uptime counter in the Hyper-V Manager when backups are taken by the DPM (r2)
The VMs that suffer from the issue are all on a new R2 cluster that uses another SOFS cluster via SMB for all VM disks.
All requirements for online backup should be in place, and all servers run fine while being backed up. When backing up the servers do create a new checkpoint, but as i understand this is the correct behavior when using DPM R2 on a Server 2012 R2 cluster.
Before installing the SMB share VSS role, and upgrading Integration services on some VMs, only Offline backup was an option, but after correcting these issues DPM allows online backup - but uptimes are still being reset.
No servers are entering saved state or otherwise being reset while backed up. Event logs show no errors regarding to "hot" backup, and the guest OS' show correct uptime when checked .
Is the resetting uptime a sign that i still have issues with online backup, even if everything seems correct? And if not, how do i avoid the uptime being reset. I know that its not technically even the correct uptime, and even resets from migrations, but still..
