Backup of the database
To back up your database, use the native program "mysqldump" of MySQL/MariaDB: Open a console, switch to the directory
<installpath-bluespice> and backup your database with the following command:
mysqldump -u <username> -p --lock-tables <database> > database.sql
<username> , use the administrative database user, and for
<database> , use the database of your MediaWiki/BlueSpice installation.
Backup of the file system
Back up the complete directory
<installpath-bluespice>, which now also includes the database image, to a different location on your server.
For security reasons, immediately delete the file
<installpath-bluespice>/database.sql, since it can be accessed from the browser.
