Amanda will handle this problem. And you can add more tapes in as
needed. Of course, someone/something has to change the tapes. One
advantage to emulating tapes on disk is that changing "tapes" can be

Amanda will write to what it calls "virtual tapes", or vtapes, as well
as tape drives. Vtapes emulate physical tapes with directories and files

I do everything with Amanda, rsync and some scripts I wrote. All free
and open source.

Amanda will do something similar; see above on vtapes. Or you can copy
to another, removable disk, and swap that out for off-site storage.
That's what I do now. You have to be careful to copy not only the
backups but also the metadata, and I have scripts for that.

Amanda actually does that reasonably well. It doesn't have tab
completion, or I'd call it excellent.
