Computers have changed the whole picture of today’s world by providing a source on which a large amount of data can be stored. The information that was once stored in a room full of files, can now be added to just one small PC. We now have paperless offices and even paperless monetary transactions with the help of computers.
Now, because computers are a medium to store your important and even confidential information, it is essential that you take measures to keep this data safe. This is because, if your computer fails, you stand the risk of losing a lot of your essential information. Some of the common causes that may lead to computer failures are:

• Software errors.
• Faulty and buggy applications.
• Program install and uninstall problems.
• Registry problems.
• Virus and spyware infections.
• User errors.
• Hardware malfunction.
• Natural disasters, such as flood and earthquake.
• Other unavoidable problems, such as fire, theft, and physical damage.

The best and the most efficient way to keep your data safe is to perform regular data backups. Today, you can make computer backups that not only help to recover your lost data, but that can also restore your operating system and system settings to have your failed computer up and running in no time.

For example, if you have a Windows Vista computer, then depending on the Windows Vista edition you own, you can choose between from Automatic Backup and Complete PC Backup features to make your backups. The Automatic Backup feature, which is available with almost all Vista editions, enables you to back up your files and folders on different types of media, including writable CDs and DVDs, external hard disk, and even on a network location. The Complete PC Backup feature, available only with Windows Vista Business, Ultimate, and Enterprise editions, performs an image-based backup of your computer. Using this feature, you can back up almost everything that is on your hard disk, including your operating system, user configuration, installed software, and data. This backup feature is useful because if your system malfunctions, you just need to restore it from the last backup and you will have your system running normally in no time.

Windows XP and Windows Vista computers also comprise the System Restore feature. If certain conditions on your system are fulfilled, the System Restore feature is enabled by default. This feature takes regular snapshots of your system configuration, system files, and registry. The feature is helpful in restoring the system configuration in case your computer encounters an irreparable error. Although useful, one disadvantage of this feature is that you cannot use if the hard disk, on which the System Restore snapshots are stored, fails.

There are many third-party tools and backup utilities also available that you can use to backup your data and system configuration. For instance, you may use a good Windows registry cleaner to maintain regular registry backups. Because the registry stores all configuration of your Windows computer, you can use the registry backup to restore the registry, in case it fails due to some problem.
You may also choose to use the services of many third-party online backup services to maintain your backups. The main advantage of using an online data backup service is that even if your entire computer system is damaged due to a natural calamity or an unavoidable disaster, your data remains safe and can be restored as soon as you have your computer systems up and running again.
