Purpose of installation: personal cloud (only one user)
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?
Thanks,
T.MG.
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
#!/bin/bash
echo "Did you make sure that backup_drive is turned on and mounted on raspi3deb?"
sudo -u www-data php /var/www/nc.example.com/occ maintenance:mode --on
#this automatically echos "Maintenance mode on"
mysqldump --single-transaction --user=nextcloud --password=XXXXXXXXXXXXXXX --lock-tables --databases nextcloud > /var/www/nc.example.com/nextcloud-sqlbkp_`date +"%Y%m%d"`.bak
echo "mysql dump created"
# puts the dump in the web root dir so I don't lose it
restic --cacert=/root/keys/public_key --password-file /root/keys/ncpass -r
# Backup to REST server on raspi3deb
rest:https://user:pass@192.168.1.100:8000/tmg/nc --verbose backup /media/ncdatadir/
restic --cacert=/root/keys/public_key -r rest:https://user:pass@192.168.1.100:8000/tmg/nc --password-file /root/keys/ncpass --verbose backup /var/www/nc.example.com/
sudo -u www-data php /var/www/nc.example.com/occ maintenance:mode --off
echo "Backup Complete. Check output for errors"
