Abstract
A computer system having a transaction based file system is disclosed. The computer system includes file system software that manages the file data and the file system structure of files stored on a persistent data storage device and maintains a transaction file that includes a plurality of transaction records. Each of the transaction records has a header section and a data section. The header section of each transaction record includes one or more fields that are designated to store information corresponding to a file transaction that is represented by the transaction record. The file system software executes a startup process in which a reconstructed file system is generated in random access memory. The startup process skips verification of the data section of a transaction record when the transaction record meets one or more predetermined criterion.
