How Safe and Secure are Online Backup Providers?
If an online backup provider is worth its salt, it will have placed great emphasis on making sure that the documents you upload and store on its servers will be safe and secure for as long as they are there. Your files should be secured from the moment they leave your hard drive and enter virtual space to the second you decide to delete them from your storage space. So exactly how safe and secure can online backup providers really be?
Security and safety as your data is uploaded
Before your files even leave your hard drive, an online backup provider will secure them using encryption – the same security measure used by banks to make sure your financial transactions are secure. This is achieved using SSL, or Secure Sockets Layer, protocol, which creates a uniquely encrypted channel that consists of a key pair and verified identification information. A “handshake” will take place between your computer and the server to establish a secure connection that will enable your data to be transferred without fear of hacking or interruption.
How does SSL encryption protect my data as it’s being uploaded?
Particularly strong encryption at 128 bits can calculate up to 288 as many key combinations as a 40-bit encryption, which is over a trillion times stronger. This may sound like meaningless jargon, but what it actually means in practical terms is that a hacker would take a trillion years to break into your transfer session using brute force.
Security and safety while your data is being stored
Another layer of protection is added to your files once they are stored on your online backup service’s servers. Generally, the solutions used by online backup services are either Advanced Encryption Standard or 448-bit Blowfish, algorithms that are used to secure sensitive material even by U.S. Government agencies
What other security can I expect from an online backup server?
Your provider will also back up its own servers. Your files won’t just be stored on a single server in one location, they will be backed up in other data servers in alternative locations at the same time. External hard drives can be damaged or destroyed by many of the same disasters your computer itself is at risk of; for example, a fire doesn’t tend to limit itself to your PC tower and is likely to spread to the storage space nearby in which you keep your external hard drive. Online backup services, on the other hand, store your data in more than one physical location, often in entirely different cities or countries. If disaster should befall one of these data centers, your files will remain safe and secure in another.
Your data will be protected and kept secure at all times by your online backup provider. You can feel safe in the knowledge that every provider will rest its reputation on making sure that your data is protected from hackers as it’s being uploaded and cannot be lost once it’s stored.
