1. The Premise: Why Portable Apps Change the Backup Game Unlike traditional installed software, portable apps are designed to live outside the operating system’s registry and protected folders. They reside on a USB drive, external SSD, or a synced cloud folder. The promise is zero footprint and total mobility.
| Layer | Content | Why It Matters | |-------|---------|----------------| | | .exe , .app , .jar , .py files | The engines themselves. Re-downloadable but time-consuming to re-collect. | | Configuration State | Data/ , Settings/ , Profile/ , .ini , .conf , prefs.js | The real value. Hotkeys, UI layouts, plugin states, recent file lists. | | User Data | Notes, project files, saved sessions, databases | Irreplaceable. Often mixed inside app folders (e.g., Keepass.kdbx , Notepad++\backup ). | portable apps backup
On Windows:
# Create a shadow copy of the drive hosting portable apps wmic shadowcopy call create Volume=E:\ # Then back up from the shadow path: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopyX\ On macOS (if using APFS): The promise is zero footprint and total mobility
For apps without relocation tools: Use a symlink. | | Configuration State | Data/ , Settings/ , Profile/ ,
Can’t incrementally sync inside the container without remounting. Works best with differential backup tools (e.g., Duplicati, Borg). 5. The Restore Drill: Why Most Backups Fail You’ve backed up. Now simulate a disaster: your USB drive dies.
