One of the pain points in Data Protection Manager 2012 is backup of the Windows System State on Windows 2008 and Windows 2008 R2
The backup created the local WindowsImageBackup folder that contains a backup of the System State , this depending on size is usually around the 10-15GB range , this does not sound as much but it’s a full change every day.
So a daily backup of 50 servers system state can be 500-750GB change on the C: drive and 500-750GB for system state , if this then needs to be moved over the WAN connection everything takes time.
And with replication as Hyper-V replica its also additional data to move to secondary site , often adding a additional drive and moving the swap and system state can help.
no WindowsImageBackup to be found anywhere
Looking at the Windows Backup Feature on the domain controller we can now see that the systemstate backup is now having the DPM server as target performing the backup over the network directly to the DPM server.
This is GREAT news ! cant believe I missed that so far.
