I am trying to backup my Nextcloud instance and practice restoring it, so I know it will work. In the past, I’ve had database corruption during an upgrade and had to reinstall, so I am trying to get backup and restore sorted before upgrading again.
I’ve followed the backup directions in the manual and have backups of the database dump, the /var/nextcloud root web folder, and the data directory.
QUESTION: How do I practice restoring the backup?
My first thought is to spin up a VM, install Debian 11, install this version of nextcloud from scratch, and restore/copy the files to the locations they should be. Is there an easier way - how would you do it?
Then I would have to restore the database. It looks like this can get quite involved, but the MariaDB docs have a “clumsy way” here Restoring Data from Dump Files - MariaDB Knowledge Base
Is this the way to practice restoring a backup, so I can restore it in case the database gets corrupted again, or I need to recover for another reason?
If you’re curious, my backup script looks like this. I would not recommend copying it as I don’t know best practices, or side effects of what I’m doing.
My backup script
