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.

A method for backing up a data set, the method comprising:
- generating one or more portions of data from the data set based at least in part on a key, wherein each of the one or more portions of data contains units of data of a respective subset of the data set that have been shuffled from an original order;
- and
- storing the one or more portions of data on one or more backup tapes by accessing a logical mount point that points to one or more backup tapes, wherein
- the data set is restorable from a threshold number of the one or more portions of data.
