Compression and Back-ups

This week i have tryed to back-up my virtual pc. Using "MicroSoft backup" i started a back-up, however this work would take 2 hours and 45 minuties and i did not have enough time. So i used "WinRar" and compressed the files i wanted to keep most and then placed them on my pen drive.
