4、per and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial: “It wont happen to
5、me. “ Well, the truth is, at some point youll probably have to deal with at least one disaster. Thats just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disa
6、ster recovery is a blind spot for many of us. It shouldnt be. Home computers contain some of our most important information, both business and personal, arid making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal c
7、omputers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and theyre even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters an
8、d minimize their effects is quite -straightforward. With a good off site storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe. Offsite Storage: Major Disasters House fires a
9、nd floods are among the most devastating causes of personal computer destruction. Thats why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their houses flood or burn. Thats because they
10、 keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computers tucked away in a closet or even the garage but theyre not nearly far enough away should a serious disaster strike. So, its important to back up your system to a removable m
11、edium and to store it elsewhere. There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldnt add to that stress. They must be dependable and intuitive, making it easy to schedule regula
12、r backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity, a backup
13、tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads. Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless However, no matter where you choose, be sure the site i
14、s secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to co
15、nventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods.

Systems crash, kids “rearrange“ data, adults inadvertently delete files. Although these events might not seem calamitous, they can have serious implications. S
17、o, once again, its important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response thats more nuanced than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and ag
18、ile. For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, youll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, youll need a way to boot your computer and
19、perform large-scale recovery. Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.
