restic is a program that does backups right.

Features

• Easy: Doing backups should be a frictionless process, otherwise you are tempted to skip it. Restic should be easy to configure and use.
• 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.
• Verifiable: 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 where the backup data is stored is assumed to be an untrusted environment.
