backup_project — Incremental folder backup with versioned naming
USAGE:
backup_project [folder] Back up a folder (or current dir)
backup_project --set-version X.Y.Z [folder] Set the next version number (respects existing folders)
backup_project --force X.Y.Z [folder] Force exact version number (ignores existing folders, one-time)
backup_project --install Install script system-wide to /usr/local/bin
backup_project --help Show this help message
EXAMPLES:
backup_project # backs up current directory
backup_project ~/Documents/this-project # backs up specified folder
backup_project --set-version 2.0.15 # next backup will be 2.0.15 (or higher if folders exist)
backup_project --force 2.0.15 # next backup will be exactly 2.0.15
backup_project --force 2.0.15 ~/Documents/this-project
NOTES:
- On first run for any folder, you will be prompted for a starting version (e.g. 2.0.12)
- Each folder has its own config stored in ~/.config/backup_project/
- Backups are created in the same parent directory as the source folder
- To reset a folder's config: rm ~/.config/backup_project/<config>.cfg
- To view all configs: ls ~/.config/backup_project/
- To uninstall: sudo rm /usr/local/bin/backup_project
