One of the most asked questions, is "How do I backup my computer?". The answer is easier than most people think. You can backup to an internal hard drive, external hard drive or across a network. In a previous article, we discussed how to map a network drive. Generally this is the safest method to backup. This type of backup ensures that if your computer is damaged, your files will be intact on a separate computer.
Network backups are efficient and allow for your data to be stored on more than one computer. The safety and security of the other computer is very important. When backing up files, you must make sure that the other computer is safe and can only be accessed by users that you trust.
External hard drives are very fast, inexpensive, and mobile. Because external hard drives are mobile, this presents a security issue in itself. On the positive side, other than the aforesaid mentioned items, the data can be moved and locked away.
