Of note from ours is we use Wasabi S3-compatible as the remote in one case and a Synology NAS as our local remote in the other. Both of those remotes fail with the unsupported state error when the backups are encrypted.
In the same encrypted job I have the following machines which have a backup size and duration of:
VM1 - 31.55GB - 47 mins
VM2 - 14.51GB - 22 mins
VM3 - 30.28GB - 48 mins
VM4 - 45.33GB - 24 mins
VM5 - FAIL - 1hr 27 min
VM6 - 2.14GB - 4 mins
VM7 - FAIL - 1hr 28 min
VM8 - 35.95GB - 1hr 5 min
The two machines erroring have thin provisioned disks whose size are
VM5 -- 128GB and 100GB which are 10.94GB and 86MB on disk
VM7 -- 123GB and 128GB which are 11.09GB and 10.3MB on disk
At first I thought it was size related or perhaps duration. But what's causing that extra duration for machines of these sizes? Something about activity on the Windows VMs?
Or perhaps that it was related to having multiple disks on Windows machines?
