Abstract
A data archive format is disclosed for archiving computer information taken from computer sessions, each session being of the form that includes a so-called 'root directory' with appropriate branches leading to each discrete file or subfile within the computer session. The archive format includes the transfer of data to an archive media member, which archive media member can alternatively be addressable or sequential memory and can be recordable in either a rewriteable or right once manner. When data is archieved, a separate and resident archived directory is created in the immediate memory of the computer having data to be archived, the purpose of this separate and resident directory being to maintain high speed during reading and writing of the archived data. This separate and resident archive directory is updated during the archiving process, used to access and retrieve the archived data during the recovery process, and distributed through the archive media in a nonpredictive, largely nonredundant but recoverable format so that upon failure of the memory containing the separate and resident archive directory, reconstruction of the separate and resident archive directory is possible.
