Archiver Process
The archiver process (dmfacp) removes completed transactions from the transaction log file and, for journaled tables, writes them to the corresponding journal files for the database. Each database has its own journal files, which contain a record of all the changes made to the database after the last checkpoint was taken. The archiver process “sleeps” until sufficient portions of the transaction log file are ready to be archived or until the last user exits from a database.
