Forever Forward Incemental Configuration

As @al3x has mentioned, your whole  operation may be handled manually, and if you select the proper RETENTION settings all will flow as you expect... a manual FULL followed by 5 manual INCs followed by your next manual FULL.  Have we understood you correctly?

OK, I see - the cleanup process depends on the schedule and not on the backup-job/scheme itself.
Unlike in Acronis, you have to handle this type of backup manually myself.

The cleanup of old backup chains by setting a retention policy is independent of schedules. So you can manually backup from within the GUI and it will still delete the old full backup chain.
