Abstract
A mechanism is provided for archiving and restoring transaction files of a database system without requiring the copying of the transaction files. A server system executes a host application that implements the database system comprising a set of database files and a set of transaction files that contains updates to the set of database files, the files being stored in a storage system. A backup engine interacts with the host application to archive a transaction file having an original filename in an original directory by creating a corresponding archive filename to the transaction file in an archive directory. The archive transaction files may be used later to perform a copy-less restore process of the database system that does not require copying of any transaction files. The copy-less restore process restores any altered original filenames by replacing, in the original directory, an altered original filename with its corresponding archive filename.
