Abstract
To restore data, substantially continuous recording of input/output (I/O) operations in a storage system is performed to provide an I/O continuum of I/O operations. Based on analyzing activity associated with the storage system, points in the I/O continuum associated with valid data are identified. Data in the storage system is restored to one of the identified points.
