After startup parameter for restart

I would like to suggest to add a parameter to the after start and before shutdown microflow that lets me know if the application is restarting without downtime.

We have a search indexer that saves the index to disk and makes a backup. If we do a restart without downtime we run into a problem.

Situation:

• second instance is loaded.
• after startup is called
• index gets restored from backup (FileDocument) to disk and is loaded into memory
• first instance is shutdown.
• before shutdown is called
• index is unloaded from memory and backed up from disk

We now have an older backup restored and are missing already indexed items. So we have to rebuild the index from scratch after a restart without downtime, because it is incorrect. With the parameter we could ignore restoring the backup and just continue. And I think there might be situations that could be the other way around so a paramter for both before shutdown and after startup look like a good idea to me.
