For many of us, our computer has become a critical part of our life. We use them for working, entertainment and corresponding with people we know. Over the course of time, most people create a number of files that are important to them and would cost time, money or both if they were lost. Data backups are the most effective way to make sure you won't lose those important files.
Many people think of backups as something large companies or computer geeks do. Or they might plan on doing it when the get the chance. Every one of those people has either already lost data due to some kind of problem with their system or they will one day. Every piece of computer equipment has a lifespan and is going to fail one day or another. When that failure occurs, one of two things will happen. If you have a backup, you'll restore it back onto your repaired computer or a replacement. If you don't, you'll be pulling your hair out over the lost files, music, digital photos and all the other stuff you store on your machine. There are, unfortunately, an infinite variety of ways to lose data. Besides hardware failure, computers can be destroyed in fires or floods. Hard drives can be damaged by power surges caused by lightning strikes or data lost by a child randomly hitting the keyboard. Viruses can infect systems and erase hard drives. But there's only one way to get it back - by having it available to be restored. What Do You Need To Backup? In most cases you don't need to backup every single thing on your computer. It can take a lot of storage space, and take a long time to complete the backup. The critical files to backup are all the things you have created, such as word processing documents, digital photos and spreadsheets, and any software you can't reinstall from the original CD or DVD. But backups need not. The easiest system for backing up your data is to just use the software that's included with most modern operating systems. Windows, Mac OS X, and Linux all include quite capable backup software. You just need to select the files and folders you want to backup and get it started. Many of these programs will even let you schedule the backup to run at a time you won't be using your computer. For a modest sum backup software can be purchased that will only backup files changed since a certain date, or since the last backup. Alternatively, new files could be copied daily to a backup folder where they can be backed-up by your backup program. To ease the task of identifying which, use the Search option to list files 'newer than X'. Once the list is complete, copy them into the backup folder and run the program for just that folder. Some files are a little tougher to backup, such as email. Some email software stores the messages on the server instead of on your computer. In those cases, you can usually save the messages into a file on your computer that can then be backed up. You can backup your information to almost any kind of removable media - removable hard drives, writable CDs or DVDs or even the USB memory sticks that are so common these days. In a pinch you may even be able to fall back on the old floppy disk. Documents don't take a lot of space and often fit into a small storage area. Daily backups are one more thing to do in a busy schedule. But the day you lose that file you need and can't restore, you're going to be a whole lot busier.
