Introduction

Datashelter is a fully integrated backup solution designed to simplify the process of backing up your Linux servers. With just a few steps, you can protect your critical data by backing up your files and databases to an S3-compatible storage system. Datashelter provides seamless setup, automated backup management, and powerful recovery features—all while ensuring your data is encrypted, compressed, and deduplicated.

Key Features​

  • Quick Setup: Backup your servers within minutes by using our easy-to-install CLI tool.
  • Automated Management: After your initial backup, Datashelter manages everything automatically. You will be notified if anything goes wrong.
  • Comprehensive Backup: Supports files and major databases (MySQL, PostgreSQL, MongoDB).
  • End-to-End Security: All backups are encrypted using AES-256 encryption.
  • Efficient Storage: ZSTD compression and deduplication ensure minimal storage usage.
  • Easy Restoration: Recover files or databases quickly and effortlessly.

How it works​

Snaper is the command-line tool (CLI) that powers the backup process for Datashelter. Built in Golang, Snaper is a powerful, lightweight tool designed to perform backups efficiently and securely from the client side. It handles everything from file and database backup to compression, encryption, and storage transfer—all within a single, easy-to-use binary.

What makes Snaper different from traditional backup solutions is its incremental backup with file-level deduplication. Unlike tools like rsync that only back up changed or added files, Snaper uses index-based backup method. Read our dedicated blogpost What is index-based backup to know more about it!

Where does Datashelter store your data​
