I do both. I make a backup to an external drive that is kept separate of my computer and I make weekly backups that are kept on a different hard drive. The only situation that I can see myself using the external drive backups in is if there was a fire or someone stole my computer. I have never used them and I doubt that I ever will (written with fingers crossed). The only reason why I make them is because my data is worth hundreds of thousands of dollars (in my eyes at least). Most people do not have that valuable of information on their computers and so it is not worth it to spend several hundreds of dollars keeping backups that they will never use.
On the other hand, I have used the backups made on my computer by WinRescue many times. Usually I have needed them because of stupid things that I have done, like unintentionally deleting files. My recommendation is to make backups of files that are important to you to a different drive. You should backup files on C to D and vice versa. Most people do not have a need to do more than that but they do need to do that. |
