Paths do not matter for dedup. Only content does.

Maybe .xva is not a good file format for deduplication?

> Using Attic in the same way I had these results

Attic has a more fine granular deduplication.

You can have that with borg, too (see --chunker-params), but if you do
that, you'll have to live with the consequences:

It will create as many chunks as attic did and will consume lots of
resources to manage them.

Contact the centos msgpack package maintainer, the package obviously
misses the compiled version of msgpack and thus it falls back to the
slower pure-python version.

You're welcome.

If you want to help your helpers, try to hit enter more often so that
not all your content ends up in one large line.

Cheers, Thomas
