This is a failover cluster via VMM so can't add host by host....
The 2 VMs with snapshots have been removed. All differential disks have been removed... All VMs are running dynamic VHDXs for the disks...Latest MS patches installed on the host & guest.
I setup a test job with 1 single VM and it took 1min 32 seconds to add the single VM.... The VM itself was added after about 10 seconds...it spent the rest of the time doing who knows what... until it decided that the it had loaded the inventory.
Ive uploaded job logs from both the single VM and the entire group...last run took 1hr 15mins to load 55 of the VMs...
Current run is 50 VMs in 1hr 1min.. This job will fail again most likely as there isn't enough time left in the Window to actually backup.
It has gotten to the point that the load time is so slow it cant complete the job in the backup window now... We have been forced to return to DPM (of all POS things) for backups of the HyperV VMs...Shoot me please!!
PS. Everything is 10Gbe on the backend.. WIth 2x LACP links for everything
