The data on the hard disk is the most critical point in the computer, and the only element that can not be replaced. E 'possible to replace an unwanted nuisance and expense of a lack of memory, monitor, or processor, but there are no data that replaces lost forever.

In addition to the possibility of a simple hard disk failure is the threat of viruses and Internet worms have become an increasing threat to data loss or corruption. Although notbe able to have absolute protection to your hard drive, there are several ways to ensure that data is protected on the hard disk. Five methods of backing up your data is summarized below ...

1. USB Flash Drives

Although I would not recommend that you use flash drive for the real data, they are a convenient way to transfer data from one computer to another. Important files can be quickly downloaded to a devicetransported as minidisk-512-DGRY-CS USB 2.0 Flash Drive, and on another computer for safe keeping. The installation and operation is extremely easy to install and, if not perhaps with a software driver, is to use a USB flash drive is a matter of freedom, with a USB port on your computer. Almost all computers produced in recent years has USB ports included, with modern systems to support the USB 2.0 standard. USB 2.0 transfers dataRates up to 480 Mb / s, which is a huge improvement over the original USB speed limit of 12 MB / s and allows users to fill their units with the data in a relatively short time.

Although the storage capacity of flash drives has increased greatly over the last year or so far as to restrict the user has full range of sizes from 512 MB to 1 GB. Mass storage is obviously not a choice, but 512 MB may be sufficient to run the backup "My Documents folder, several albums of MP3s, or otherimportant files stored on another site.

2. CD and DVD Writer / Re-Writer

The falling prices of CD and DVD writers / re-writers have an integral part of almost all modern computers. These devices can typically be found installed in a slot machine, but external devices supporting USB 2.0 or Firewire are available for greater flexibility and ease of installation.

A combination of units, such as the NU Technology DBW-521, the user is a high-speed CDReader / writer and a DVD player for under $ 40. The extremely low price for the unit (and empty) provides a cost-effective way to create backup copies and re-writable media increases the comfort by moving to erase the disc and reused many times. The main limitation of using a CD burner for backups is that the discs are generally limited to a capacity of 700 MB per disk. Not enough for a full backup, but adequate for archiving keyFile.

The popularity of DVD writers / re-writer moves through falling prices, and urge the stand-alone CD burner for destruction. DVD offers the user far more storage capacity of a CD-ROM and DVD burners can burn a CD, in general, as well as DVDs. The recent availability of double-layer DVD burner, like the Sony DW-D22A-DO-N, represents a significant increase in the capacity of writable DVDs, taking the previous limit of 4.7GB per disc and nearly doubling 8.5 GB.

With proper storage, CD / DVD provides a long-term storage, which can not be jeopardized by hardware failure. Data on a CD or DVD can be easily read by most computers, making it a good choice for archiving files that are not excessively large.

3 Hard Drives

As the name might suggest, are generally the same type of drive you might find in your system, but external hard drives housed in a smaller,> Enclosure for himself. The container consists of at least one data interface (eg, Firewire, USB or Ethernet), and the ability to function is limited only by the size of hard drives currently available, and budget.

The Ximeta NetDisk is an example of an external hard drive that a user can connect an extra 80 GB, 120 GB or 160 GB of memory to your system using either through a USB 2.0 or Ethernet connection.The installation of such a device is very simple and can include the installation of some basic software and the necessary connections between the computer and the outer fence.

The capacity of external hard drives makes them comfortable for backing up large data sets, and many of these devices simplify the process, including software (or hardware) to automate the backup feature.

For example, some Seagate Driveshave a "one-button" backup option right on case.In not only a convenient method for backing up large volumes of files locally, most external hard drives are compact enough to be portable. The inclusion of a common interface data transfer, such as USB, allows an external hard drive on almost all modern computers for data transfer, or be connected to more parts of an external computer hard driveas a backup.

4. More Hard Drives

By using an additional hard drive for your system, you can protect yourself against data loss using is not the primary unit for the slave drive. Installing a second hard disk, but a basic knowledge of the inner workings of a computer to request the disincentive some users. We offer a "how-to" section on our site for many taskshow to penetrate the installation of a hard disk into a computer system.

To take the installation to install a second hard disk to another level of security and reliability, the hard drive in a RAID array. RAID stands for Redundant Array of Independent (or Inexpensive) Disks, and can be configured in different ways. A detailed discussion of RAID and all its variants, would be an article in itself, but what is of interest,Talk is that known as RAID 1. A RAID 1 array requires two hard drives of equal size on a RAID controller installed, which will then mirror one drive to another in real time. Many motherboards with onboard RAID controllers come, but the addition of a PCI controller card, like the Silicon Image Sil0680 is to buy a cheaper, which will contribute to any RAID system. Available with a RAID 1 array if a disk fails, theDo not miss the best system to run more on the remaining disk well, and warns the user that a unit that needs replacing.

5. Online Storage

Online services like Xdrive, which users upload their files on a server for safe keeping. Even if it is appropriate in some circumstances, the available data, which have an Internet connection available, there are some limitations.

The services typically pay a monthly fee based on the amount of storage spaceSpace. At Xdrive, for example, 5 GB of storage costs $ 9.95 per month, which can easily spend up to more of a discussion in any of the other options.

Security is very tight as these services, but no matter how safe it may seem, is still only a password to keep prying eyes from potentially sensitive documents.

The speed of your Internet connection is also strongly influenced by the comfort of your backup weigh, and no matter what kind ofConnection you have, can not compete with local data transmission speeds.

Final words

Although not a complete list of available options for backing up data, which offer the five points listed some simple and relatively inexpensive way of ensuring that data is never lost. Data loss is extremely frustrating and potentially costly situation, but that can be avoided.
