Android phone backup → local PC → external HDD

Build a reliable local backup flow on Windows 11. Phone files land in one staging folder on this PC, then your scheduled HDD backup job copies that folder to external storage.

Recommended staging layout

Keep all phone backup data under one predictable tree. This makes scheduled copy jobs simpler and less error-prone.

Android-Phone/
  incoming/                # Syncthing receives here
  usb-snapshots/
    YYYY-MM-DD/            # Manual USB snapshots by date
  adb-snapshots/
    YYYY-MM-DD/            # Optional power-user ADB pulls
  logs/                    # Optional copy logs

LAN backup (default): Syncthing

• Install Syncthing on Windows and Android, then allow Windows firewall access on private networks.
• On PC, create/select receive folder: `...\Android-Phone\incoming\`.
• On phone, share source folders (start with high-value folders, then expand).
• Disable battery optimization for Syncthing on Android to improve sync reliability.
• First sync can take time; verify file counts before deleting anything from phone.

USB backup: MTP snapshots

• Connect phone via USB and choose file transfer mode (MTP).
• Copy visible phone storage folders into a dated snapshot folder: `...\Android-Phone\usb-snapshots\YYYY-MM-DD\`.
• Use this path for occasional full grabs or when Wi-Fi sync is slow.

Optional power-user path: ADB pulls

If you use Android developer tools, you can pull known directories. This is optional and not required for the default setup.

# Example commands (after installing platform-tools):
adb devices
adb pull /sdcard/DCIM      "D:\Backups\Android-Phone\adb-snapshots\YYYY-MM-DD\DCIM"
adb pull /sdcard/Documents "D:\Backups\Android-Phone\adb-snapshots\YYYY-MM-DD\Documents"

What “everything” means here

This guide targets broad user-accessible storage coverage, not every app's private internal data.
