I noticed that while overwriting some of my Feature Services to my ArcGIS for Server, a second service is created once the process is run and complete. It has the name of my primary service that I'm overwriting but then has "_20161201203" for example, a time stamp of sorts. My question is what should I be doing with this and is there any purpose for it? I tried looking in the help for the tool but didn't find anything on this. I've attached a screen shot to illustrate what I'm talking about when viewing the services in Server Manager.
note: these feature services are being deployed for consumption by a third party software to access, update, add, delete data in an SQL database.
