I keep my server (on my peer to peer) clean... other than some shared files (documents) and AC, there ain't much there. So imaging the server is not an issue for me.
I totally agree that simply getting a message that you have a back up is not sufficient. I would be interested in hearing more specifics about how people test their back ups. I think that a restore to a sandbox machine is the only reliable way. Do the experts agree?
I have a test server that I lug around to some of my client offices and I restore their backups onto that server. If their backups are to the cloud, I just download the backup myself onto the test server in my office. Other times the client sends me their backup via Fed-Ex. I then have the client inspect the server to make certain the data is as it should be. For example, QuickBooks has all the transactions it should have, last few new patients entered into Amazing Charts, etc.
