To have a warning prompt that comes up prior to putting a backup device into seeding mode in the event that there had been an failed or aborted session that occurred prior to run a seeding backup. When an aborted backup runs it will create cabinet structures but it fails to fill it with data due to the backup being manually ended. In the event that the backup manager detects that, the user should be prompted saying that their could be data loss with the seed upload due to this session, avoiding having to use -invalidate-missing-data
