This can be done, but don’t remove the drive in middle of backup, and start-on-plugin is awkward.
The basic rule is that the local database that tracks the destination must pair with that destination.
Nice way to get that is to put it right on the destination drive using the Database screen to move it.
Backup rotation on removeable drives fails after drive change
What exactly does “directly support” mean? It’s definitely not a primary goal, but may work enough.
That concept also applies if you have paying clients. Will they take Beta software as good enough?
No software is perfect. Duplicati runs 50 million backups per year (good enough?) but issues exist.
