I had it up and running in a few minutes - tried their support (reactive, competent) and had 50GBytes backed up from my Mac to our family-PC (yes, we're still using it...) within a few hours...
Elegant UT - a cool addition to my backup strategy... (20-50 Euro).
Update (Sept 07): I verified the following things to make sure it works as expected:
- Simple restore of a file or a previous version. Crashplan can keep arbitrary versions :-)
- Restore from a different machine, so I can restore files even if the original machine is stolen, burnt down, drowned or otherwise unavailable.
- Asking support questions: The CrashPlan support guys are responsive, friendly and competent. Excellent marks here!
