Backup/Restore NextcloudDB

DB data is stored in /opt/mariadb and backed up along with Saltbox Backup.

However, you can separately make a backup of the DB into a single nextcloud_backup.sql file, by running the following command.

docker exec mariadb /usr/bin/mysqldump -u root --password=password321 nextcloud  > nextcloud_backup.sql

And restoring it back:

cat nextcloud_backup.sql | docker exec -i mariadb /usr/bin/mysql -u root --password=password321 nextcloud

JSON Format Errors

Python or script errors mentioning an issue with the config file is usually due to an invalid JSON format in the file.

Examples:

Fixes:

  1. Paste the JSON file at jsonformatter.curiousconcept.com and click process. This will tell you what the issue is and fix it for you.

or

  1. Run:
jq '.' config.json

If there are no issues, it will simply print out the full JSON file.

If there is an issue, a msg will display the location of the issue:

parse error: Expected separator between values at line 7, column 10
