- Removed 40+ broken/messy scripts, moved to old_scripts/ - Created lvm_block_backup.sh - proper block-level LVM snapshot backup - Uses dd for block-level cloning instead of file-level rsync - Successfully tested: 462GB backup in 33 minutes - Creates exact, bootable clone of internal drive to external drive - Proper LVM snapshot management with cleanup - Clear documentation in README_BACKUP.md - Clean, minimal solution that actually works
