Yes you need backups and no RAID is not a backup. That would also cover the falling of the table scenario.

Backups can be easily done via USB, remote encrypted offsites or using a second device for synching and cold standby.

You can always call us during the warranty period - from our experience this rarely happens. Yes we do sell maintenance packages outside the warranty terms. We dispatch technicians and with those maintenance packages you don't need to pay for that.

We use ZFS RAID 5 and while it's a great way to make sure that you can recover from 1/4 drive failures, 2/4 drive losses will be bad.

And yes you're right on the full disk encryption - and this is something we'll be shipping in one of our upcoming releases which happen on a monthly basis.
