Anything that tampers with the Library folder can corrupt. Only Calibre should make changes. The DB is the link between the entry and the files. Delays can allow a cart before horse condition, thus the rule of NOT on a Network storage.

BTW your screenshot is NOT of Calibre Library (the typical folder where books are)
Thank you, agin for your response and clarrfification.

You are correct, the screenshot I sent is not from Calibre, I accessed it through
Preferences > Miscellaneous > Open calibre cofiguration folder

Now, I have 2 questions:

1- My undestanding is that given that I have already performed the restore, the metadata.opf for each book has been overwritten and the custom columns settings have been lost. However, if I have a backup of the library which includes the metadata.opf files before restoration, I should be able to restore the custom columns through the metadata editor. The issue is that I could not find the option "Set Metadata from book files" . Question: I would appreciate that you point me to that option.

2- Does backuping up the library using Time machine considered tampering with the Library folder? If no, that is goog. If, yes, what is the best practice to have a disaster recovery plan?
