摘要： In one embodiment, a user or client device is connected to a distributed file system comprised of one or more physical nodes. The data on each of the physical nodes store metadata about files and directories within the file system. Some of the embodiments permit a user to take a snapshot of data stored on the file system. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories. According to one embodiment, the system stores and updates metadata, including a governance list, for each of the files and directories. The governance list provides a representation of the snapshots which govern a file or directory and its descendants.

摘要： Systems and methods are disclosed that provide an indexing data structure. In one embodiment, the indexing data structure is mirrored index tree where the copies of the nodes of the tree are stored across devices in a distributed system. In one embodiment, nodes that are stored on an offline device are restored, and an offline device that comes back online is merged into the distributed system and given access to the current indexing data structure. In one embodiment, the indexing data structure is traversed to locate and restore nodes that are stored on offline devices of the distributed system.

In one embodiment, the metadata comprises mini-snapshots for directories representing a path from the root of the file system to the root of the snapshot. The mini-snapshots serve as stand-ins for portions of the file system which are not included in the snapshot, but which permit access to the snapshot data in an intuitive way.

In one embodiment, previous versions of a file or directory are stored only in response to a request to modify the file or directory. The system creates and updates a snapshot tracking data structure which provides information regarding each file or directory governed by the snapshot that was modified or deleted after the snapshot was taken. The snapshot tracking data structure may be used by the system to perform functions related to the snapshot, including deleting the snapshot.
