Simple-Backup

A lightweight, configurable backup tool for creating local archives of your important files. This tool creates compressed backups on your local filesystem that can be easily transferred to external storage or cloud services.

Overview

Simple-Backup provides:

• Configurable backup sources and destinations
• Support for both TAR (high compression) and ZIP (faster) archive formats
• Pattern-based file exclusion
• Cross-platform compatibility on Linux systems

Installation

You can install Simple-Backup system-wide to run it from anywhere:

# Clone the repository
git clone https://github.com/yourusername/simple-backup.git
cd simple-backup

# Run the setup script
./setup.sh

The setup script will either:

1. Create a symlink in /usr/local/bin if you have write permissions
2. Prompt you to run with sudo if needed
3. Offer to add the directory to your PATH in ~/.bashrc

After installation, you can run the backup command from any directory.

Configuration

Create new backup jobs by adding JSON configuration files to the configs/ directory. Each configuration file should include:

Field	Description
outputDir	Directory where backups will be saved (supports ~ for home directory)
inputs	List of directories/files to back up
ignorePatterns	List of patterns to exclude from backup
archiveType	Either "tar" (default, higher compression) or "zip" (faster, better compatibility)
remoteLocation	Optional. Remote location for backup copy using scp format (e.g., user@host:~/path)

Example configuration:

{
    "outputDir": "~/backups/",
    "inputs": [
        "~/Documents/",
        "~/Pictures/"
    ],
    "ignorePatterns": [
        ".git/",
        "node_modules/"
    ],
    "archiveType": "zip",
    "remoteLocation": "user@remotehost:~/backups/"
}

Running

You can run backups manually or as a scheduled task:

Manual Execution

# Once installed, simply run:
backup

# Or from the repository directory:
./backup.py

Scheduled Execution (Linux)

Add a cron job to run backups automatically, for example weekly on Saturday at 1:05 AM:

sudo crontab -e
# Add this line:
5 1 * * 6 /path/to/simple-backup/backup.py >> /var/log/simple-backup.log 2>&1

Exclude Patterns

The exclusion system uses simple string matching:

• Patterns are matched against the full file path
• No regex or glob syntax is supported
• For directories, adding a trailing slash (e.g., .git/) will exclude the directory and all its contents

Remote Backup

With the optional remoteLocation setting, Simple-Backup can automatically:

1. Check if the remote server is accessible
2. Ensure the target directory exists on the remote server
3. Copy the backup file via SCP after local backup completes

This requires:

• SSH key-based authentication set up between your local and remote machines
• The remote server must be accessible via SSH
• You must have write permissions to the specified remote directory

If the remote copy fails for any reason, the local backup will still be preserved.

What's Next?

If not using the remote backup feature, you'll need to manually copy your backups to external storage or cloud services like Proton Drive, Google Drive, or Dropbox for off-site backup.
