“save pipeline into file vs restorepipeline into file”
By this I assume you are referring to these services
pub.flow:savePipelineToFile
pub.flow:restorePipelineFromFile
Close inspection of the service names makes the difference between the services quite clear. The Built-in Service Reference also describes how these two services work.
If these are not the services to which you are referring, then perhaps you can post what you mean by and where you heard “save pipeline into file vs restorepipeline into file.”
