To add to your fears I had catastrophic syncing issues last few. Stupidly enough I had turned off local backups thinking Google would be better. 10gb of design files gone.
I still haven't worked out what happened but there where 5 computers syncing the files at work, something got muddled and deleted everything off all the computers at once. All I know for sure is somehow they where modified by a person who wasn't at work that day (and hence not on there PC). They where then deleted, but not available in the online trash, gone off all computers but not moved to the local trash as the forums so it should of, and all history had disappeared from the online drive.
They still appeared how ever if I did a search for them, you just couldn't navigate to them or find them in through any other part of the UI. So I did manage to zip them all up and get my data back.
Anyway lesson learned, and for me its dropbox and local backups from now on. All trust lost for me. I have no idea if it was syncing, an error in the cloud, or someone in the office, but yeah total loss of trust for me.
Dropbox, Google Drive, Skydrive are more of folder mirroring, much like RAID is data mirroring. Any good sysadmin will remind you that RAID provides protection against hardware failures, but in no way is data backup or protection. Onsite and Offsite backups are always important.
