A method of capturing a fractional snapshot of a distributed file system includes receiving a snapshot request to generate a factional snapshot of a file system. The request includes an indication of a subset of data of the file system. The method further includes identifying, by a processing device, the subset of data of the file system indicated by the snapshot request and generating the fractional snapshot comprising the subset of data of the file system indicated by the snapshot request.

Fractional consistent global snapshots of a distributed namespace

In one embodiment, a method includes creating a first number of streams for a file system manager of a deduplicating storage system to access concurrently a type of data blocks, where each stream is for one file system and is identified by a stream identifier. The method further includes mapping stream identifiers to each of the type of data blocks passing through the first number of streams. The method further includes accessing the type of data blocks in storage units of the deduplicating storage system through a second number of streams, where the second number of streams are dedicated to the type of data blocks in the deduplicating storage system, where the second number is smaller than the first number, where the data blocks are tracked according to the mapped stream identifiers, and where the data blocks are stored in the storage units after a deduplication process to remove duplication.
