As a rule of thumb all data should have three backups in two different media and one additional location. The additional location in the case of SMBs could be the cloud as they already have one backup on premise.
Need for data protection
There are two kinds of people in the world: Those who have lost critical data, and those who will. In other words, if you use technology long enough and neglect to back up your data, you're guaranteed to have at least one extremely bad day. Whether it's theft, loss, fire, flood, corruption, or some form of malware, a single incident can destroy the lion's share of your family photos, personal documents, address books, years-in-the-making music library, and more.
The solution, of course, is to back up everything. With ever-increasing amounts of data to be stored, real threats of data loss, and increasing government legislation, data protection has become a high priority. It is not just large and enterprise corporations that must protect their data. Even SoHo's and SMBs need to evolve a data protection strategy that is commensurate with their needs and budget. Having a data backup plan is akin to having a insurance policy. You need it for any eventuality.
According to PCWorld magazine, few years ago, the terms "disaster recovery" and "data protection" were synonymous with large budgets and an army of IT personnel to manage the process. Cost is relative, though. Paying a monthly or annual fee for an online backup service seems more expensive than just burning a DVD at face value, but it's all worth it when the office is destroyed by an accident or natural calamity and the DVDs are scratched and cracked in half, and you can just set up a new computer somewhere else and restore your data from the Web.
Today's business environment of low cost disks, robust software, and high-performance tape drives enables companies of all sizes to proactively protect themselves from data loss and its threats to the business.
Backup imperative for SMBs
For many small businesses, though, their backup and storage strategy hasn't caught up with their more pervasive use of computers. This could be due to confusion about the various storage options, or a failure to understand that the old paradigm of the occasional batch backup is no longer adequate.
Storing your backup copies on premise provides for fast recovery. However, having only one copy of backup on premise does bear the risk of being damaged in case of any eventuality. The cloud offers a perfect location for the additional backup for these businesses. Further, growing acceptance of the bring your own device (BYOD) trend and increasing maturity of cloud services has opened the door for businesses to store data online.
