Restoring Calibre From Backup

The metadata.db holds the library and app.db and gdrive.db contain the web/account information.

Place books directories in /data/books/.

Place metadata.db in /var/lib/calibre-web-db/.

Symlink metadata.db to the library:

sudo ln -s /var/lib/calibre-web-db/metadata.db /data/books/metadata.db

Place app.db and gdrive.db in /var/lib/calibre-web/.

Restart Calibre:

sudo systemctl restart calibre-web.service
