Oh yes, Beyond Compare does both the comparison AND the synching (+ a bunch of other useful things) and does it very well, I’d like to add.

Mostly because of what I read here about NOT to use clouds (Google Drive in the first place) as storage AND synching place for the main calibre library - reportedly, due to library data corruption occurring in the process of cloud-synching which then makes the uploaded version useless for restoring the library from there.

Hence, I was thinking of a „packed“ version of the library (e. g. those part-xxxx.calibre-data chunks when using calibre’s „Export…“ feature) in the hope they would be less prone to corruption when uploaded to and synched with a cloud.

(I have also learned here that the a. m. data corruption was more often than not user-induced: running calibre AND synching to a cloud at the same time. I hope I got it right.)

Providing the machine you're restoring to has a working version of calibre that supports its import/export feature it should be OK.
Yes, that is what was on my mind: to be able to restore the main library (if need be) actually onto the same machine on which it got messed up for one reason or another.

No XP machine in my case, I am on a Mac ;-)


Many thanks again!
