The average computer user with a USB port should be able to backup their photos, music and documents in almost no time at all and for so little money that it make no sense not to do it religiously.
I know I am guilty of not backing up my files regularly but then I am not creating new files or uploading music or photos to my computer that often.
When I get nervous about it, or when I have done a bunch of scanning of old photos or uploaded a bunch of new music, I pull out my thumb drive, plug it in to my USB port and drag and drop my My Documents file to the thumb drive, then go get a cup of coffee. Keeping all my files in my My Documents file makes it easy to back up. (I also save stuff to my desktop--not really a good idea as my desktop gets pretty cluttered--so I copy my desktop over as well).
After I've made my backup, I sit down to make a quick check to see how much got saved by checking the size of my My Documents file on my computer against the size of my My Documents file on my thumb drive. They should be the same though there could be a slight difference--not more than a few kilobytes. I also check to see how full my thumb drive is by checking its properties. It it's getting pretty full, I know its time to buy a larger thumb drive.
Thumb drives are very inexpensive and can save up to a 30 plus gigabytes for around $25.00 (or 100 plus gigabytes portable flash drives for around $80.00). At these prices, it is wise and affordable to buy two or three thumb drives and backup to these in rotation--that is, backup to one then the next time, backup to the other. That way you have two fairly recent backups--it is not unheard of for thumb drives to malfunction so if one goes kaput, you still have the data from the other.
If you have hundreds of, say, photo files at high resolution, you may want to make two good backups of your older files on portable flash drives that you store in a safe, dry, cool place. You should not have to back up these files again. Save any new pictures to a new file folder. Copy the new file folder only when you do your backup. Files sometimes get corrupted on your hard drive unbeknown to you. If you re-backup old files, you might find that you are backing up corrupted files.
