As more people run their own homelab, Docker stacks, and self-hosted services, having a reliable, automated, and simple backup system becomes essential. Zerobyte was created precisely to solve that problem.

Zerobyte is a lightweight backup automation framework designed specifically for self-hosters. It focuses on:

  • Automated backup workflows

  • Easy integration with Docker and bare-metal setups

  • Snapshot-style versioned backups

  • Compatibility with Linux servers and cloud storage

  • A built-in terminal-based UI for monitoring backups

Built using POSIX-compatible shell scripts, Zerobyte runs virtually anywhere.


🎯 1. Purpose of Zerobyte

Zerobyte aims to provide a backup solution that is:

  • Lightweight – just shell scripts, with minimal dependencies

  • Fast – optimized for quick backup and restore operations

  • Secure – supports versioning and snapshot integrity

  • Automated – cron-ready with built-in scheduling commands

  • Extendable – anyone can write plugins for new apps or services

For homelab enthusiasts and self-hosted environments, it is a clean, practical solution.


βš™οΈ 2. Installation

Installing Zerobyte is straightforward:

git clone https://github.com/nicotsx/zerobyte.git
cd zerobyte
./install.sh

After installation, you gain access to:

  • zb – the main command-line tool

  • Plugin directory structure

  • Configuration templates

  • Automation scripts


πŸ“¦ 3. How Zerobyte Works

Zerobyte operates using a plugin-based architecture.
Each backup target (e.g., MySQL, folders, Docker volumes) is represented as a plugin:

backup.sh
restore.sh
config

This architecture allows Zerobyte to support:

  • Application backups

  • File system backups

  • Databases

  • Docker data folders

  • Directory-level snapshots

  • Cloud upload targets

Additional features include:

  • Versioning – keep multiple versions per backup

  • Retention policies – auto cleanup of older snapshots

  • Scheduling – via cron or Zerobyte scheduler


🧩 4. Creating New Backup Plugins

Creating plugins is extremely simple.

Generate a new plugin:

zb plugin new myapp

A minimal plugin example:

backup.sh

backup() {
    tar -czf "$BACKUP_DIR/myapp.tar.gz" /var/lib/myapp
}

restore.sh

restore() {
    tar -xzf "$1" -C /
}

Because everything is pure bash, customizing behavior is effortless.


πŸ–₯️ 5. Terminal UI – Monitoring Your Backups

Zerobyte includes a TUI (Terminal User Interface) allowing users to:

  • Browse all available backups

  • Check each plugin’s status

  • View timestamped snapshots

  • Trigger manual backups

  • Inspect logs

A typical TUI view may show:

Name: MySQL
Status: OK
Backup versions:
 - 2025-11-15
 - 2025-11-16

This makes management convenient even without a web interface.


πŸ§ͺ 6. Backup Verification

One of Zerobyte’s strengths is built-in verification:

zb verify mysql

Verification includes:

  • File integrity checks

  • CRC testing

  • Ensuring restore scripts run properly

  • Content extraction validation

This guarantees that backups are not only created but reliable.


πŸ” 7. Automated Scheduling with Cron

Scheduling backup jobs is simple.

Built-in scheduler:

zb schedule daily mysql
zb schedule hourly nextcloud

Or add custom jobs manually:

0 3 * * * zb backup all

πŸš€ 8. Creating a New Backup Job

You can create structured backup jobs:

zb job new

Example configuration:

name: mysql-nightly
plugins:
  - mysql
schedule: daily
retention: 14 versions

Zerobyte handles:

  • Running the schedule

  • Versioning

  • Automatic old-backup pruning


🌐 9. Cloud & Remote Backup Support

Zerobyte supports various remote targets:

  • S3-compatible storage

  • Wasabi

  • Backblaze B2

  • FTP / SFTP

  • SSH + rsync

Example:

zb remote add myb2 s3 b2://bucket-name
zb backup mysql --upload myb2

This allows safe off-site backups following the 3-2-1 backup rule.


🧰 10. Render Plugin – Creating Backup Reports

Zerobyte can generate human-readable reports:

zb render html > report.html

Useful for:

  • Email summaries

  • Backup dashboards

  • Archiving status reports


πŸ“ƒ 11. License & Contribution

Zerobyte is open-source (MIT License).
Users are encouraged to:

  • Fork the project

  • Submit pull requests

  • Create new plugins

  • Report issues or improvements

The project is community-friendly and fully transparent.
