The biggest problem I encountered during the archive project was figuring out how to transfer the files from the server to my laptop. I ended up using the pscp command in the windows command prompt. Creating the archive and compressing it seemed straight forward. I like that the two can be separate that way you can create and archive without compressing it just to keep the files together. Also you can compress a single file without having to archive it.
