US Patent 7765190 Pseudosnapshot creation and implementation using continuous data protection

Systems and methods for performing replication operations on a continuous data protection system. In one embodiment, a method includes identifying at least a portion of the series of transactions on the continuous data protection system to be included in the pseudosnapshot, identifying an initial time at which the pseudosnapshot begins, identifying a final time at which the pseudosnapshot ends, identifying a last transaction before the final time at which the pseudosnapshot ends, and creating an event marker identifying a particular point in time that the last transaction was saved on the continuous data protection system.
