Data Security
The following are only some of the measures we use to keep your data secure.
All communications between our backup servers and your systems are transported in a 128-bit or optional 256-bit SSL (Secure Socket Layer) channel. Although all your backup files travel through a public network (the internet), outsiders have no knowledge of what has been sent or received.
All of your files are first compressed and then encrypted with your defined encryption key. To everyone except you, your data stored on our servers are nothing more than a random stream of bits.
The encryption key used to protect your files resides only in your systems and is known only to you. It is never transmitted anywhere. Thus, even our system administrators are not able to decrypt and view the content of your files without your permission and assistance. This does mean, however, that if the key is lost, you will not be able to recover your data.
The algorithm that used to encrypt your data a block cipher designed by Counterpane Labs. It was also one of the five Advanced Encryption Standard (AES) finalists chosen by National Institute of Standard and Technology (NIST). The algorithm is subjected to frequent public review and no known attack against this algorithm has been reported.
A 128-bit key has 2128 or around 3.4 x 1038 possible combinations. It has been calculated that a brute force attack using a 12.3 teraflop (trillions of operations/second) supercomputer would need 8.77 x 1017 years to attempt all the possible key combinations. The earth is not that old. A 256-bit key has 2128 x 2128 possible combinations, making this key incomprehensibly more difficult to attack.
You can also restrict access to your backup files from the set of IP addresses you defined. If someone tries to access your data from an IP address not on your list, their access will be denied. This additional security ensures backup files are not open to all locations, even if username and password are known.
Additional measures, which we do not disclose, are also in place.
