File Server Archive settings

hello @Ajal 

Thanks for the great question!
A server plan is going to protect all data during the backup operation based on what is outlined in the subclients to protect. 

An Archive plan is going to do the same but its selection is more refined as it could be items older than X or larger than X. A backup job is run and will protect data but only the data that meets its criteria. 

So if in your environment you want a full protection of your environment you will need the service plan and then also run the Archive plan to stub the data that meets the criteria. The archive plan will run a backup job of the data it is stubbing to make sure it has the latest version of that data but it wont protect the entire server.

I hope this answers your questions. 

Kind regards
