Abstract
A portable data protection system is described for protecting, transferring or copying data using continuous data protection (CDP) over intermittent or occasional connections between a computer system or mobile device containing the data to be protected, transferred or copied, called a data source, and one or more computer systems that receive the data, called a data target. CDP can be broken down logically into two phases: 1) detecting changes to data on a data source and 2) replicating the changes to a data target. The portable data protection system uses a method that performs the first phase continuously or near continuously on the data source, and the second phase when a connection is available between the data source and the data target.
