Backup system

About

To backup all my servers data I use Restic. Restic use (here) rclone internally to backup everything on pCloud.

The backed up data includes mainly container volumes (configs) and docker-compose (from Portainer ).

Restic

Restic is a modern backup program that can back up your files

• to many different storage types, including self-hosted and online services
• easily, being a single executable that you can run without a server or complex setup
• effectively, only transferring the parts that actually changed in the files you back up
• securely, by careful use of cryptography in every part of the process
• verifiably, enabling you to make sure that your files can be restored when needed
