Claim:
1. A method of backing up data from a source file system of a computer device to a backup data storage system, the method comprising: checking whether a source file is locally stored on the source file system in a local deduplicated format of the source file system by performing application programming interface (API) calls to an deduplication control module of the source file system of the computer device to determine whether the source file is stored in the local deduplicated format, wherein the deduplication control module controls deduplication operations associated with source files locally stored on the source file system; when the checking indicates that the source file is stored in the local deduplicated format, then when the check indicates that the source file is stored without deduplication on the computer device, then backing up the source file by transferring data chunks of the source file to the backup data storage system and performing deduplication on the data chunks of the source file.
