Data storage format for addressable or sequential memory media

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