Patent Images
1. A method of providing data backup, the method comprising:
- receiving at a virtual tape backup system a data image to be maintained;
transmitting the contents of the data image to a secure storage appliance;
processing the contents of the data image with the secure storage appliance to cryptographically split one or more blocks of data of the data image such that each of the one or more blocks of data is split into a plurality of secondary data blocks; and
storing the plurality of secondary data blocks in a corresponding plurality of shares located on a plurality of physical storage devices.

Abstract
A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.
