The three big rules for surviving with a library "in the cloud" are:
  1. Never rely on just the cloud copy and the local copy in your sync'd folder. Keep a complete backup copy of your library in an unsync'd location. Evil things can easily happen and leave the library unrepairable, at least without massive effort. A clean backup is very very very desirable.
  2. Never allow syncing while using calibre.
  3. Never allow multiple copies of calibre to access the same library at the same time.
How about Microsoft OneDrive. Is that any safer than Dropbox?
