+# Backup Scripts
+
+A collection of shell scripts for creating and restoring backups of disks, directories, and folders on Linux systems.
+
+## Overview
+
+This repository contains three backup utilities:
+
+- **`backup`** - Universal backup tool that handles both disks and directories
+- **`backup_disk`** - Specialized tool for disk/partition backups
+- **`backup_folder`** - Specialized tool for directory backups using SquashFS
+
+## Requirements
+
+- Linux operating system
+- Root privileges (all scripts require sudo/root access)
+- Basic utilities: `dd`, `gzip`
+- Optional: `mksquashfs`/`unsquashfs` for SquashFS compression
+- Optional: `tar` as fallback for directory backups
+
+## Installation
+
+1. Clone or download the scripts to your system
+2. Make the scripts executable:
+   ```bash
+   chmod +x backup backup_disk backup_folder
+   ```
+3. Optionally, move them to a directory in your PATH (e.g., `/usr/local/bin/`)
+
+## Usage
+
+### Universal Backup Tool (`backup`)
+
+The main backup script that can handle both disks and directories automatically.
+
+#### Create Backup
+```bash
+sudo ./backup --create --disk /dev/sda --file backup.img.gz
+sudo ./backup --create --directory /home/user --file home_backup.sqsh
+```
+
+#### Restore Backup
+```bash
+sudo ./backup --restore --file backup.img.gz --disk /dev/sda
+sudo ./backup --restore --file home_backup.sqsh --directory /home/user
+```
+
+#### Options
+- `-c, --create` - Create a backup
+- `-r, --restore` - Restore from backup
+- `-d, --disk, --directory <path>` - Source disk or directory
+- `-f, --file, --filename <path>` - Backup file path
+- `-h, --help` - Show help message
+
+### Disk Backup Tool (`backup_disk`)
+
+Specialized tool for creating compressed disk images using dd and gzip.
+
+#### Create Disk Backup
+```bash
+sudo ./backup_disk create /dev/sda disk_backup.img.gz
+```
+
+#### Restore Disk Backup
+```bash
+sudo ./backup_disk restore disk_backup.img.gz /dev/sda
+```
+
+### Folder Backup Tool (`backup_folder`)
+
+Specialized tool for creating compressed directory backups using SquashFS.
+
+#### Create Folder Backup
+```bash
+sudo ./backup_folder create /home/user folder_backup.sqsh
+```
+
+#### Restore Folder Backup
+```bash
+sudo ./backup_folder restore folder_backup.sqsh /home/user
+```
+
+## Features
+
+- **Smart Detection**: The universal `backup` script automatically detects whether the source is a disk or directory
+- **Multiple Compression Methods**: 
+  - SquashFS for directories (preferred)
+  - tar as fallback for directories
+  - gzip compression for disk images
+- **Progress Monitoring**: Shows progress during disk operations
+- **Error Handling**: Validates inputs and provides helpful error messages
+- **Flexible Usage**: Multiple command-line argument formats supported
+
+## Safety Considerations
+
+⚠️ **WARNING**: These scripts perform low-level disk operations and can cause data loss if used incorrectly.
+
+- Always verify disk paths before running restore operations
+- Test backups in a safe environment first
+- Ensure you have sufficient disk space for backups
+- Double-check source and destination paths
+- Consider using `--dry-run` options when available
+
+## Examples
+
+### Complete System Backup
+```bash
+# Backup entire disk
+sudo ./backup_disk create /dev/sda system_backup.img.gz
+
+# Backup home directory
+sudo ./backup_folder create /home home_backup.sqsh
+```
+
+### Selective Restore
+```bash
+# Restore only home directory
+sudo ./backup_folder restore home_backup.sqsh /home
+
+# Restore full system (be very careful!)
+sudo ./backup_disk restore system_backup.img.gz /dev/sda
+```
+
+## File Formats
+
+- **Disk backups**: Compressed with gzip (`.img.gz`)
+- **Directory backups**: SquashFS format (`.sqsh`) or tar archives (`.tar`)
+
+## Troubleshooting
+
+- **Permission denied**: Ensure you're running with root privileges
+- **Command not found**: Install missing dependencies (`squashfs-tools` for SquashFS support)
+- **No space left**: Check available disk space before creating backups
+- **Invalid device**: Verify disk paths with `lsblk` or `fdisk -l`
