Unfortunately I found out today that I messed up my calendars about three days ago while synchronizing between two Thunderbird instances. On my server I have a backup of both the Nextcloud directory and the database (mariaDB) from before the accident. However, I donât want to completely restore the backup from four days ago, because otherwise I would miss the changes of the last three days. A solution I have in mind would be to compare both calendars and merge them back together manually. Do you have any ideas how I can best achieve this goal? In another post I read that the calendars are stored in the database. Can I extract them from there as calendar files without having to restore the whole Nextcloud?
Many thanks for your hint! Exporting the current calendar is of course quite easy via the web interface, but how do I get the old calendar backup (from the database backup) without resetting the complete Nextcloud?
Thanks again for the hint! If I get you right, you meant the âDoes this also work with a broken ownCloud/Nextcloud instanceâ part of the README, right?
My hosting provider has backups of my databases with this scheme: â/path/to/mysql-backup/nextcloud_something.sql.xzâ
Now how do I get the ânextcloud_dummy/config/config.phpâ to use the database from this backup instead the âliveâ database? I guess I have to restore the backup as a new database first and then adjust the âconfig.phpâ accordingly - but honestly I donât know if this is right and how I do such restore.
