◆ execute()

LocalFileRestoreBatch::execute ( )

Run the transaction, except the cleanup batch.

The cleanup batch should be run in a separate transaction, because it locks different rows and there's no need to keep the image row locked while it's acquiring those locks The caller may have its own transaction open. So we save the batch and let the caller call cleanup()
