Backing up computer files

<p>I bought the Western Digital 1TB MyBook with eSATA yesterday and am in process of putting everything on that external drive. Unfortunately our computer doesn’t appear to have eSATA capacity, which would make the transfer 5x faster, but it is nice to know it’s there for when we upgrade. This drive also works with a Mac and had the software (WD Anywhere Backup) built in. We pushed a single button and it went to work, apparently copying 100% of what is on the computer now, which is what I want. In retrospect, I should have told it to only work when the computer was idle because it slows it down too much. Going through a USB port will take several days to complete the full back-up. Tomorrow morning when I have to work, I may need to stop the program in order to get anything done. I looked at the HELP manual for the hard drive and it was a nothing. I need to read the help manual for the softwhere, but don’t want to disturb it until it is done. I just hope stopping it after 36 hours and then restarting doesn’t lose what has already been saved, but it shouldn’t. Every GB closer I get to being backed up makes me feel better.</p>

<p>One last question. When using an external hard drive for back-up, can a virus get into that and destroy everything? Does that mean I have to unplug it when not using it for back-up? I was hoping to delete a lot of the files on the internal drive after I have put them on the external drive to free up space on my computer so it runs faster, but I would still like access to them so don’t want to have to keep the external drive unplugged, but will if leaving it plugged in defeats the whole purpose.</p>
