Abstract
Methods and apparatus for archiving files in a system with primary storage and secondary storage that reduces thread contention. A single input reader thread generates list of files for processing by multiple map threads that evaluate each file in a list against a number of archive policies, such as move, purge, index and delete. Reduce threads take the lists from the map threads and generates list of files for action under a given policy, e.g., move, purge, index, delete. This arrangement eliminates thread contention for files and lists.
