No backup? No excuse!
In many parts of the United States you do not have to buy things online to get quality PRODUCTS at low prices. Well, not in the case of good quality hard disk drive backup.
Here is a page I got off of the Wal-Mart site. Notice you can buy a very big Western Digital backup SYSTEM for under $100. Or, if you prefer Seagate you can get the 500 GB for even lower price. By the WAY, in this DISCUSSION when we use the letters GB it represents the idea of gigabyte in base 10 notation.
Look at his link I just found.

This is not an endorsement of WalMart. But just yesterday I went to mom WalMart and saw that they did have the Western Digital tetra bite box for less than $100. But not just one or two, they had a stack of them.
So there's no excuse for not having no backup system unless you're absolutely positively broke. Just a brown bag your lunch for a month and you should have enough money to buy one of these.
Now the question.
No backup?
What is your excuse?
Why buy from Walmart when you can buy from here:

NAS are better for me than External Hard Drives because I can connect and backup multiple PC's through my network.
