Adding a somewhat irrelevant but perhaps related comment to this thread it would be great if the final release of 12.5 would include multiple backup rules!

With some "crontab fiddling", this is already possible.
There are many ways to schedule (cron) tasks, with the possibility to have a (custom, in a sense "advanced") backup task scheduled.
However, I would not recommend "multiple" backup rules, since this could result in various errors (for instance, simultaneously running backup processes) and/or result in extensive usage of disk space and cpu AND, more important, it is not really necessary.
To illustrate the lack of necessity, consider backup settings that allow daily backups, with at most 3 copies in the (local or remote) backup directory.
In essence, this type of scheduled back up task takes care of daily backups and, as such, also backups at a monthly interval (as taken from the illustration in your link).
In short, a "multiple" backup rules would be a double and unnecessary rule.
However, consider the same scenario, but now with a requirement to retain (for example) monthly backups (as taken/derived from the illustration in your link).
Again, no necessity for "multiple" backup rules would exist, when considering the option to create a separate (scheduled) backup task for storing backups on a remote (FTP) backup directory (and note that this is "good practice", i.e. a remote location for backups that should be retained).
In fact, the backup settings also apply to the remote (FTP) backup directory, implying that backups are created monthly AND retained during 3 months, given the number of copies.
In conclusion, it is often more practical to fiddle with backup settings, just make smart use of the option in Plesk to separately set scheduled backup tasks for both local and remote backups.
Nevertheless, it would be nice to have more control over backup settings, any additional option in backup settings would be much appreciated, to that I do agree.
Kind regards.....
