Do not put your calibre library on a networked drive.

A filesystem is a complex beast. Most network filesystems lack various filesystem features that calibre uses. Some don’t support file locking, some don’t support hardlinking, some are just flaky. Additionally, calibre is a single user application, if you accidentally run two copies of calibre on the same networked library, bad things will happen. Finally, different OSes impose different limitations on filesystems, so if you share your networked drive across OSes, once again, bad things will happen.

Incidentally my Box library is synced to a Mega cloud library and then MegaSync downloads it to my tablet, so I'm happy that I'm well backed up. I use Calibre Sync to access the Mega Library and used to use Calibre Companion to look at the Box Library.

I have to admit that I've not bothered to keep up with Calibre's development as everything has worked perfectly for me for years.

Does Calibre not officially support cloud Storage?
