Abstract
The subject disclosure is directed towards the parallel backing up of a file system. A file system tree structure is walked by parallel workers that write file system data to data storage devices in parallel streams. Work assigned to one worker may be split to an idle worker to provide parallel operation. Relationship data that maintains relationships between the streams is persisted (e.g., via reference data inserted into the streams) so that a restore mechanism is able to stitch the streams together back into the file system data. Also persisted is location data that maintains storage locations of the streams. A file's data also may be written into parallel streams.
