Backup inconsitent setting for web- and mysql- interval possible but no individual option on ISPConfig

There is no option in the ui to set web and database backup intervals individually. At least not shown to me.

The database table web_database has the interval stored in 'backup_interval'.

It seems to be possible to have a web set to daily and database to weekly. Though one is only able to set the web interval effectively on ISPConfig.

Also in some situation there seems to be a missing synchronisation of those fields https://forum.howtoforge.com/threads/backups.92260/#post-455918

My assumption is that in some scenario the interval field does not get updated.

Also it should be a possible option in the UI to set those individually, then one would be see a wrong value in the future.
