I wrote ddar before I knew about bup. It doesn't have this limitation; you can arbitrarily remove any archive. However, it does not do encryption, so I wouldn't recommend using it to store on S3 directly.

I actually tried again today, and this is still promiment in the limitations:

bup currently has no features that prune away old backups.

Because of the way the packfile system works, backups become "entangled" in weird ways and it's not actually possible to delete one pack (corresponding approximately to one backup) without risking screwing up other backups.

Thanks for pointing that out. Encryption is not really an issue for me. It's very easy to perform encryption using a encrypting FUSE filesystem or afterwards when needed.
