At the current time the subverse is mostly reliant on archive.is to retain information. I might be wrong but I think information is only archived for 7 months? Regardless if archive.is has a timeframe it is beneficial have the capability of keeping local archives on personal hard drives.

This is a program named HTTrack. This free software has been around for years and works pretty good. This software can automatically download a website and the links within it.
