CB 4.4 on Server 2012 R2

Trying to get unattended backups to run.
Server is up and running, but no accounts are logged in.
Trying to run scheduled backups as a Service to a local drive to test.
Doesn’t seem to want to run. No error code returned.

Q’s

  1. Am I running the right version for Server 2012?
  2. Does this need an account logged in to run under even though it is set to run as a Service?

Thanks.
