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

An intelligent method of handling incremental backups concurrent with load balancing movement. The file system uses placement tags, incremental backup requests and capacity balancing data movement to make intelligent decision to avoid affecting any backup windows for clients or backup apps. The file system tracks capacity balancing file movements inside the cluster. When switching locations of files in a cluster from one node to another, it is performed as an atomic change of switching inode attributes by the file system after the contents of the file have been copied over to the new node. During the file movement for capacity balancing, the file system handles requests for full backups differently than requests for incremental backups. The file system continues to handle virtual systhesis and fastcopy requests on the node that hosts the previous backup to ensure that the incremental backup succeeds with the expected smaller backup window from the client.

Optimizing incremental backup for clients in a dedupe cluster to provide faster backup windows with high dedupe and minimal overhead

A method system and process for managing connection stream is discussed. A count is incremented and/or decremented as connections are established. If the count equals a threshold, additional connections are rejected.

Active stream counts for storage appliances

Techniques for implementing logical trunk groups with session initiation protocol (SIP) are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for implementing logical trunk groups with session initiation protocol (SIP). The apparatus may comprise a first network device and a second network device that are configured to exchange SIP signaling messages. Network traffic between the first network device and the second network device may be segregated into one or more logical groups. The SIP signaling messages associated with each logical group may include a Route header that uniquely identifies the logical group between the first network device and the second network device.
