Backup that Valuable Data with an External Hard Drive

No matter how much you might think that your computer is "bomb" proof, having an external hard drive is essential to backing up all of those valuable files. The need to backup your hard drive becomes a key point if your business happens to be deeply vested in the IT industry. There are definitely several different manufacturers to choose from when it comes to choosing an external hard drive. It all comes down to storage space required, method of transfer, backup frequency and, of course, cost.

Backing up your hard drive is an essential step towards retaining all of that valuable data. No matter what, at some point in time, the hard drive built into your computer is going to fail. Hard drives have moving parts and moving parts break down over time. The best way to be prepared for this event is by backing up the files that you don't want or can't afford to lose, onto an external hard drive. Deciding which external hard drive to choose from when it comes to the matter of storage space is an easily answered question. Get as much as you can for what you can afford. External hard drives range in price from $80 to $300 or more, depending on your requirements.

Choosing the external hard drive of your dreams shouldn't be difficult if you know what you are looking for. Most external hard drives will start out with about 250GB storage capacity and a transfer rate of 480Mbps via a USB 2.0 connection. The performance continues to escalate from there. At the top end of the scale: 2TB storage capacity with a transfer rate of 3Gbps via a FireWire 800 or eSATA connection.

Deciding which kind of connection you should use will depend on how fast of a transfer rate you actually need. For most applications, the USB 2.0 connection will be completely adequate. If you, however, need a great deal of speed, then the FireWire 800 or eSATA connection would be best. The USB is standard on just about all of the devices in use today, so, it won't cost you anything extra. The FireWire and eSATA may give you greater speed in transfers but they will cost you more, not only for the hardware but the software as well. On top of the cost issue, you will need to be sure that your existing system is compatible. If not, it is probably better to stay with the USB connection and settle for slower transfer rate.

The last consideration for backing up your files is what frequency or how often you will be doing the backups. If you have a constant flow of information coming and going from your computer, then having software designed for real time or constant back up is for you. Another format for backing up files is having a programmed backup schedule for your files. It won't keep all of your backups completely current all of the time but the automation is handy. Last but not least, some people prefer to manually backup their files, giving them the control over exactly which files will be backed up or not.
