For what it may be worth: I have been using Calibre since its first version. All that time, the library has been in a folder that Dropbox backs up. For a while, I ran Calibre on two computers and had all the problems others have mentioned. But once I stopped running a second copy of Calibre many, many years ago (and stopped making changes to the relevant folder outside of Calibre)I have had no problems.
YMMV.
On the plus side, I have changed computers at least six times over the years and just installing Calibre and pointing it to the library folder worked fine each time.
