Well, I'm glad I found this thread, I'm having nearly the same problem

My set though is with OneDrive, and only 3500 books. The books are all there, but I have had multiple copies of the same sets of books and sometimes folders in my library.

I know that there was a problem I was having with Onedrive downloading and syncing the same books over and over again, and Windows (in it's programming genius) added the (1) or (2) or (1) (1) to the book listings, metadata and covers. This had the effect of taking my 9 GB library and making it nearly 40 GB. The folders of the authors which contained copies of some of the book records had a "_" (underscore) added to the end of the author's name, but no similar entry in the library. I have found several recreations of the same book in different folders with different index numbers at the end of the title.

Some of these errors I've been able to fix with a library maintenance scan, but there's thousands of books that were just lost.

I'm replicating my Calibre library on OneDrive, not storing it there. The database runs from the local PC, and I use OneDrive to give me a backup. I also use COPS to replicate it on my website where I log in with COPS to pull down an OPDS version of the library as I sometimes want to pull a book down when I'm away from my home network.

Never used Calibre on two different systems at once.

I think I have the additional books with the replicated (1) etc handled. Got several programs and figured out ways to let Windows find the affected files, deleted them and I *hope* that it replicates up to the OneDrive. Then ran the library scan and found all the files that Calibre thinks doesn't belong, mostly MOBI copies of books already in the library.

So, right now I'm doing a database restore. If this doesn't work, I'm moving the library, readding the books that are "missing" and seeing where I stand from there.
