Techniques are provided for key-value store and file system integration to optimize key value store operations. A key-value store is integrated within a file system of a node. A log structured merge tree of the key-value store may be populated with a key corresponding to a content hash of a value data item stored separate from the key. A random distribution search may be performed upon a sorted log of the log structured merge tree to identify the key for accessing the value data item. A starting location for the random distribution search is derived from key information, a log size of the sorted log, and/or a keyspace size of a keyspace associated with the key.

Key-value store and file system integration

Data protection methods and systems for a storage environment are provided. A first-in-first out (FIFO) structure stores a logical representation of a first storage location that retains previous data for a data container, after new data for the data container is stored at a second storage location. The FIFO structure also stores a logical representation of a file system tree structure that is stored in persistent storage, after a consistent point operation. In response to an event, the file system tree structure is selected, based on the file system tree structure being closest to a transaction. A snapshot is generated using the file system tree structure. Thereafter, the data container is restored from the snapshot or from a copy of the snapshot.

Data protection methods and systems for a networked storage environment

Presented herein are system and method for providing a non-disruptive mechanism for splitting a parent volume located on a first aggregate into a new volume, the method comprising: splitting the parent volume, by the network storage system, into a new volume, wherein the new volume comprises an application; and providing a snapshot of the parent volume at the new volume.

Non-disruptive automatic application regrouping

Many applications and computing environments, such as data storage systems, provide data backup and restoration features. It may be advantageous to provide file level backups that may be accessible to a user through a directory structure of a file system. Accordingly, fileshots comprising backup data of a file may be stored as metadata of the file. For example, a fileshot may be stored within a stream directory as a hidden stream linked off of the file. Fileshots may be associated within a directory interface (e.g., a command prompt or graphical user interface), which may be presented to a user. In this way, the user may access and/or manage fileshots through the directory interface (e.g., the user may create fileshots, restore files with fileshots, copy fileshots, etc.). Additionally, fileshot metadata may be maintained for fileshots. The fileshot metadata may be used to locate fileshot and/or perform fileshot commands.
