Hi,
rdiff-backup-fs was an archived project [1] to create a userspace (fuse)
file system for a backup repo created by rdiff-backup.
I have neither time nor the necessary skills to revive the project but
the concept is cool so I imported the code [2].
Anybody having some C skills, feel free to stand up and look if the code
is worth anything and can be revived for modern kernels/Linux. Pull
requests very welcome!
Happy hacking,
Eric
