Consider creating a test-specific factory method or builder pattern instead of adding constructor parameters solely for testing purposes. This approach would keep the production constructor clean while providing the necessary test control.

This assertion Assert.True(true, ...) is a no-op that always passes and provides no meaningful test validation. Either implement proper command testing or remove this placeholder assertion.

[nitpick] Consider adding a buffer size parameter to CopyToAsync for better performance with large files. The default buffer size may not be optimal for all file sizes in the backup/restore scenario.
