Restic Design Principles
|
|
========================
|
|
|
|
Restic is a program that does backups right and was designed with the following
|
|
principles in mind:
|
|
|
|
* Easy: Doing backups should be a frictionless process, otherwise you might be
|
|
tempted to skip it. Restic should be easy to configure and use, so that, in
|
|
the event of a data loss, you can just restore it. Likewise,
|
|
restoring data should not be complicated.
|
|
|
|
* Fast: Backing up your data with restic should only be limited by your
|
|
network or hard disk bandwidth so that you can backup your files every day.
|
|
Nobody does backups if it takes too much time. Restoring backups should only
|
|
transfer data that is needed for the files that are to be restored, so that
|
|
this process is also fast.
|
|
|
|
* Verifiable: Much more important than backup is restore, so restic enables
|
|
you to easily verify that all data can be restored.
|
|
|
|
* Secure: Restic uses cryptography to guarantee confidentiality and integrity
|
|
of your data. The location the backup data is stored is assumed not to be a
|
|
trusted environment (e.g. a shared space where others like system
|
|
administrators are able to access your backups). Restic is built to secure
|
|
your data against such attackers.
|
|
|
|
* Efficient: With the growth of data, additional snapshots should only take
|
|
the storage of the actual increment. Even more, duplicate data should be
|
|
de-duplicated before it is actually written to the storage back end to save
|
|
precious backup space.
|

============
|
|
|
|
Install Go/Golang (at least version 1.3), then run `go run build.go`,
|
|
afterwards you'll find the binary in the current directory:
|
|
|
|
$ go run build.go
|
|
|
|
$ ./restic --help
|
|

|
Compatibility
|
|
=============
|
|
|
|
Backward compatibility for backups is important so that our users are always
|
|
able to restore saved data. Therefore restic follows [Semantic
|
|
Versioning](http://semver.org) to clearly define which versions are compatible.
|
|
The repository and data structures contained therein are considered the "Public
|
|
API" in the sense of Semantic Versioning.
|
|
|
|
We guarantee backward compatibility of all repositories within one major version;
|
|
as long as we do not increment the major version, data can be read and restored.
|
|
We strive to be fully backward compatible to all prior versions.
|
|
|
|
Contribute and Documentation
|
|
============================
|
|
|
|
Contributions are welcome! More information can be found in
|
|
[`CONTRIBUTING.md`](CONTRIBUTING.md). A document describing the design of
|
|
restic and the data structures stored on the back end is contained in
|
|
[`doc/Design.md`](doc/Design.md).
|
|
The development environment is described in [`CONTRIBUTING.md`](CONTRIBUTING.md).
