Generate and attach an external disk

  1. Create a new disk from the Disks section of the Compute Engine console
  2. Edit your instance details and add the new disk as an additional disk to your instance1
  3. Save the changes
  4. Start the instance

It is also possible to create the external disk when creating the instance.

From this point the external disk will be mounted on /data and will be seen as the instance internal storage by the Android OS.

Migrate the external disk to another instance


The original and target instances should have the same Android version. If versions are different, we cannot guarantee the result.

  1. Edit your original instance details and remove the external disk from Additional disks
  2. Edit your target instance details and add the external disk in Additional disks > Attach existing disk


If the instances are running, they will reboot when the external disk is removed or attached.

The original instance internal storage /data will then replace the target instance one - all the applications and settings installed in the original instance will be available in the target instance.

  1. If your instance is already running, it will automatically reboot to mount the external disk.
