" ... it may be that it is not possible to restore from a mirrored device when doing a VMware restore"
This must be a bug (or is it a feature)
I seems to be the same for Exchange integration.
It's senseless (and dangerous for those who don't know it) to have a "media mirror" option with no function.
Now we have to change our Backup and Restore strategy because it won't work.
I'm really frustrated.
