Restic

Overview

Restic is a fast, secure, and efficient backup program. Every backup is encrypted (AES-256) and deduplicated at the block level, meaning only changed data is stored on subsequent runs. It supports multiple storage backends: local disk, SFTP, S3-compatible storage (AWS, MinIO, Backblaze B2), Azure Blob, Google Cloud Storage, and more. This skill covers repository setup, backup and restore operations, snapshot management, retention policies, and automation.
