I'm aware of the ZFS special VDEV approach but that's not what I'm looking for here. I'm looking for two separate repos: one that handles all the snapshot files and the other that handles all the chunks. This way I'd be able to sync them separately to S3 and do immutable things that current iterations of PBS aren't doing.
Then again, if PBS is close to actually supporting immutable S3 repos I'll spare myself the engineering time to work around the issue.
