# Introduction
|
|
|
|
restic is a backup program that is fast, efficient and secure. It supports the three major operating systems (Linux, macOS, Windows) and a few smaller ones (FreeBSD, OpenBSD).
|
|
|
|
For detailed usage and installation instructions check out the [documentation](https://restic.readthedocs.io/en/latest).

|
|
|
|
Quick start
|
|
-----------
|
|
|
|
Once you've [installed](https://restic.readthedocs.io/en/latest/020_installation.html) restic, start
|
|
off with creating a repository for your backups:
|
|
|
|
$ restic init --repo /tmp/backup
|
|
enter password for new backend:
|
|
enter password again:
|
|
created restic backend 085b3c76b9 at /tmp/backup
|
|
Please note that knowledge of your password is required to access the repository.
|
|
Losing your password means that your data is irrecoverably lost.
|
|
|
|
and add some data:
|
|
|
|
$ restic --repo /tmp/backup backup ~/work
|
|
enter password for repository:
|
|
scan [/home/user/work]
|
|
scanned 764 directories, 1816 files in 0:00
|
|
[0:29] 100.00% 54.732 MiB/s 1.582 GiB / 1.582 GiB 2580 / 2580 items 0 errors ETA 0:00
|
|
duration: 0:29, 54.47MiB/s
|
|
snapshot 40dc1520 saved
|
|
|
|
Next you can either use `restic restore` to restore files or use `restic
|
|
mount` to mount the repository via fuse and browse the files from previous
|
|
snapshots.
|
|
|
|

# Backends
|
|
|
|
Saving a backup on the same machine is nice but not a real backup strategy.
|
|
Therefore, restic supports the following backends for storing backups natively:
|
|
|
|
- [Local directory](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#local)
|
|
- [sftp server (via SSH)](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#sftp)
|
|
- [HTTP REST server](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server) ([protocol](https://restic.readthedocs.io/en/latest/100_references.html#rest-backend), [rest-server](https://github.com/restic/rest-server))
|
|
- [Amazon S3](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#amazon-s3) (either from Amazon or using the [Minio](https://minio.io) server)
|
|
- [OpenStack Swift](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#openstack-swift)
|
|
- [BackBlaze B2](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#backblaze-b2)
|
|
- [Microsoft Azure Blob Storage](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#microsoft-azure-blob-storage)
|
|
- [Google Cloud Storage](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#google-cloud-storage)
|
|
- And many other services via the [rclone](https://rclone.org) [Backend](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#other-services-via-rclone)

# 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.
|
|

# Reproducible Builds
|
|
|
|
The binaries released with each restic version starting at 0.6.1 are
|
|
[reproducible](https://reproducible-builds.org/), which means that you can
|
|
reproduce a byte identical version from the source code for that
|
|
release. Instructions on how to do that are contained in the
|
|
[builder repository](https://github.com/restic/builder).
