[$] Back In Time back from the dead

Back In Time is a GPL-2.0-licensed backup tool based on

rsync and written in Python. It has both graphical and command-line interfaces, and
supports backups to local disks or over SSH.
Back In Time was originally written by
Oprea Dan and released in 2009. The tool has been
through some rough patches over the years, and is currently on its third set of
maintainers. Christian Buhtz, one of the current maintainers, explained to me
how he and his co-maintainers had revived the project, as well as why he thought
Back In Time stood out from all of the existing backup solutions.
