Abstract

A log device is coupled in the logical data transfer path between a storage device, which provides for the storage of file and system data within a main filesystem layout, and a computer system. The log device provides for the storage of the file and system data within a log structured filesystem layout. A control program is executed to manage the storage of file and system data in data segments in the log device filesystem and to selectively transfer the file and system data from the log device to the storage device. The control program utilizes location data provided in the file and system data to identify a destination storage location for the file and system data within the main filesystem layout.
