Attic is a deduplicating backup software for various Unix-like operating systems.
History
Attic development began in 2010 and was accepted to Debian in Aug 2013. Attic is available from pip and notably part of Debian, Ubuntu, Arch and Slackware.
Design
Attic offers efficient, deduplicated, compressed and (optionally) encrypted and authenticated backups.
A backup includes metadata like owner/group, permissions, POSIX ACLs and Extended file attributes. It handles special files also - like hardlinks, symlinks, devices files, etc. Internally it represents the files in an archive as a stream of metadata, similar to tar and unlike tools such as git. The Borg project has created extensive documentation of the internal workings.
Attic uses a rolling hash to implement global data deduplication. Compression defaults to zlib, encryption is AES (via OpenSSL) authenticated by a HMAC.
Borg
In 2015, Attic has been forked as “Borg” to support a “more open, faster paced development”, according to its developers.[3] Many issues in Attic have been fixed in this fork, but backward compatibility with the original program has been lost (a non-reversible upgrade process exists). Borg 1.0.0 was released on 5th March 2016.
As of 2017, Borg is under active development by many contributors[4] while Attic is not being developed.
Stable releases are available from various Linux distributions such as Debian, Ubuntu, Fedora, OpenSUSE and others, and from the ports collection of various BSD derivatives. The project provides pre-built binaries for Linux, FreeBSD and macOS.
