It's always important to remember the difference between a syncing service and a backup service. A syncing service sometimes feels like a backup, because you can use it to recover files if a local device is destroyed or lost. HOWEVER, any service capable of syncing files is equally capable of destroying them.
It's important to have an automated one-way backup system that you can manually restore from. Something like Tarsnap [1] looks like a really good possibility (I haven't used it myself, but it seems solid)
