Impossibly large file at ~/.orbstack/data/data.img

Update from OrbStack

This is intended behavior that allows us to implement more seamless storage management. More details

Describe the bug
I received a notification from Backblaze that it was unable to backup my machine as my disk is running low on space.

To Reproduce
Steps to reproduce the behavior:

  1. Open OrbStack
  2. Wait...
  3. Run ls -hla ~/.orbstack/data/data.img and observe the size.

Expected behavior
There will not be a file larger than the system disk.

Logs
None of the logs seem to reference data.img

System info

  • macOS version: 13.0.1 (22A400)
  • CPU architecture: Arm

Additional context

ls -hla ~/.orbstack/data/data.img
-rw-r--r--@ 1 wizardfrag  staff   8.0T 10 Mar 17:12 /Users/wizardfrag/.orbstack/data/data.img

I suspect this is a sparsely allocated image file, and should possibly just be ignored by Backblaze, but I thought it might be worth reporting it!
