@KuJoe got a bit zoned in on the maintenance window issue - they're great at being available! But you're right, it's more an enterprise solution (aka SMB to enterprise budget) for endpoint backup.
Wouldn't we all love to have a grand budget?
Hey Raindog,
Have you heard of Druva inSync?
1. I've seen Crashplan's Enterprise customers expressing the same sentiments
2. At Druva, they understand how important access to data is, when you need it..and hence the 7 9's and 11 9's. Never worry about backup restores, you can do it any time...
