restic is a backup program that is fast, efficient and secure. Detailed information can be found in the documentation and the user manual. The design document lists the technical background and gives detailed information about the structure of the repository and the data saved therein. The file FAQ.md lists the most frequently asked questions.

The latest documentation can be viewed online at https://restic.readthedocs.io/en/latest. On the bottom left corner there is a menu that allows switching to the documentation and user manual for the latest released version.

Install restic

You can download the latest pre-compiled binary from the restic release page.

Build restic

Install Go/Golang (at least version 1.7), then run go run build.go, afterwards you'll find the binary in the current directory:

$ go run build.go

$ ./restic --help
  restic [OPTIONS] <command>

You can easily cross-compile restic for all supported platforms, just supply the target OS and platform via the command-line options like this (for Windows and FreeBSD respectively):

$ go run build.go --goos windows --goarch amd64

$ go run build.go --goos freebsd --goarch 386

The resulting binary is statically linked and does not require any libraries.

More documentation can be found in the user manual.

At the moment, the only tested compiler for restic is the official Go compiler. Building restic with gccgo may work, but is not supported.

Contribute and Documentation

Contributions are welcome! Please open an issue first (or add a comment to an existing issue) if you plan to work on any code or add a new feature. This way, duplicate work is prevented and we can discuss your ideas and design first.

More information and a description of the development environment can be found in CONTRIBUTING.md. A document describing the design of restic and the data structures stored on the back end is contained in doc/Design.md.
