This has nothing to do with Egypt but being a old geek, do pass on worthwhile hints. I have set this up for my personal computer and clients. It is the remote feature that is most attractive. Connect a External Drive, backup folder files (initial backup fast this way), move to another computer, or friends, in remote location, and let it update automatically over the net. ALL FREE and easy with a bit of study.
If you want to pay a bit, you can also backup to the cloud with Crashplan + or Crashplan Pro.
