Add DB Backup to Maintenance

Added the possibility to perform a backup of the database. This creates a "pending" backup (a copy of the database) and from it an archive with the current date. The "pending" backup is overwritten with the next backup. The status information on the maintenance page has been supplemented accordingly.
