Comment by ThomasWaldmann

at first it was implemented to easily test permission restricted storages (can't easily test on all sorts of cloud storages).

it was implemented for "file:" (which is also used for "ssh://" repos) and there are automated tests for how borg behaves on such restricted permissions repos.

after the last beta I also added cli flags to "borg serve", so it now also can be used via .ssh/authorized_keys more easily.

so it can now also be used for practical applications, not just for testing.

not for production yet though, borg2 is still in beta.

help with testing is very welcome though!
