# LVM Block-Level Backup Tool
|
|
|
|
## What This Does
|
|
|
|
This tool performs a **proper** LVM snapshot backup by:
|
|
|
|
1. ✅ Creating consistent LVM snapshots of your internal drive
|
|
2. ✅ Cloning entire volumes **block-for-block** to external drive
|
|
3. ✅ Creating an exact, bootable copy of your system
|
|
4. ✅ Using full drive capacity efficiently
|
|
|
|
## Why This Is Better
|
|
|
|
- **Fast**: Block-level copying is much faster than file copying
|
|
- **Complete**: Exact bit-for-bit copy including all metadata
|
|
- **Bootable**: External drive can boot your system directly
|
|
- **Space Efficient**: Uses full drive capacity, no filesystem overhead
|
|
- **Consistent**: Snapshots ensure data consistency during backup
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
# Simple one-command backup
|
|
sudo ./lvm_block_backup.sh
|
|
```
|
|
|
|
## Requirements
|
|
|
|
- Both drives must have LVM setup
|
|
- External drive volume group: `migration-vg`
|
|
- Internal drive volume group: `internal-vg`
|
|
- At least 6GB free space for snapshots
|
|
|
|
## What Gets Backed Up
|
|
|
|
- **Root volume**: Complete system, applications, configurations
|
|
- **Home volume**: All user data (including encrypted LUKS)
|
|
- **Boot volume**: Kernels, bootloader, boot configuration
|
|
|
|
## Result
|
|
|
|
After backup, your external drive contains an exact copy that can:
|
|
- Boot independently from BIOS/UEFI menu
|
|
- Be mounted to access files
|
|
- Serve as complete system recovery
|
|

**Note**: The `old_scripts/` directory contains 40+ previous backup attempts that didn't work properly. This single script replaces all of them. |
