One issue with using rsync as a "backup" solution is that you get a copy of what is currently on the server. If you have to go back even just a week, much less several months, to get some specific version of a file from months before, you can't do that with rsync.
That's partially a difference between openrsync(1) and rsync(1) but more about how you have scripted their use. Point the destination at a different target directory each day (or other interval) and you can go back at least a little, depending on how deep that stack is and how much space you have on the storage device being used for backup.
In old rsync(1) you also have --link-dest which allows you to save space on the destination partition by using hard links on the target partition for files in a new backup directory which have not changed relative to the reference directory. The big tradeoff with --link-dest is that there ends up being only a single copy on that particular partition. But if you're only using openrsync(1) then --link-dest is not relevant.
However, since you do have multiple backup media anyway, those multiple devices should be part of the rotation strategy / calculations.
