An anonymous reader writes: After almost a year of development, bug fixing and cleanup, BorgBackup 1.0.0 has been released. BorgBackup is a fork of the Attic-Backup project — a deduplicating, compressing, encrypting and authenticating backup program for Linux, FreeBSD, Mac OS X and other unixoid operating systems (Windows may also work using CygWin, but that is rather experimental/unsupported). It works on 32bit as well as on 64bit platforms, x86/x64 and ARM CPUs (maybe as well on others, but these are the tested ones). For Linux, FreeBSD and Mac OS X, there are single-file binaries which can be just copied onto a system and contain everything needed (Python, libraries, BorgBackup itself). Of course, it can be also installed from source. BorgBackup is FOSS (BSD License) and implemented in Python 3 (91%), speed critical parts are in C or Cython (9%).
