For those that don't know, rsync.net now has full, native[1] support for both attic and borg.
Our longstanding "HN Readers" discount make it very affordable. Just email us.
[1] Native, as opposed to pointing attic to a local sshfs mount point that terminates at rsync.net, which is what we used to offer to attic/borg users. We don't have a python interpreter in our environment, so it was not easy to provide those tools. We solved the problem by (cx)freezing the attic and borg python tools into binary executables. So, still no python in our environment (reducing attack surface) but the ability to run attic and borg just like they are meant to be run.
