Completely unsupportable. Even Veeam isn't technically supported and I've seen it cause problems.
You take an app level backup and restore that.
everything but ACR is quick, easy, simple and supportable.
Or, use a SAN.
Either way, your servers should at least have 2 disks in RAID 1 for no single point of failure and if the server dies, get another of the same and just pop the disks in.
