The disclosed computer-implemented method for applying content-based retention policies to data artifacts may include (1) identifying one or more features of a data artifact detected on a computing system, (2) identifying a collection of data artifacts that are (A) stored on at least one storage system and (B) retained in accordance with a set of retention policies, (2) determining, based at least in part on the features, that the data artifact detected on the computing system and at least one data artifact within the collection exceed a certain level of similarity relative to one another, (3) analyzing at least one retention policy of the data artifact within the collection, and then (4) providing a suggestion to apply the retention policy of the data artifact within the collection to the data artifact detected on the computing system. Various other methods, systems, and computer-readable media are also disclosed.

A host of a multi-device file system may instruct an external data mover implementing a third party copy to move data from one storage device to another without the host reading or writing data as part of the move. The data being moved may remain accessible through the file system after being moved. A host may instruct an external data mover to write moved data to multiple mirrored devices. A host may instruct the data mover to move data between storage classes in a multi storage class file system. A journaling file system may utilize an external data mover implementing a third party copy to move data from a system log to another storage destination and may also instruct the data mover to move metadata as well as data.

Method and apparatus for data moving in multi-device file systems

Configuration data, such as options a file system accessed by a host system, may be stored on the storage device storing the file system. File system configuration data may be stored in a file of the file system or in a private storage area configured for storing file system configuration data. A host may access the file system configuration data and subsequently may access the file system according to the file system configuration data. Additionally, different versions of file system configuration data may be stored and different hosts accessing the file system may read and use different versions of the file system configuration data based upon the type or context of the host accessing the file system. Storing file system configuration data with the file system data, or on the same storage device, may allow context dependent options to be provided to various hosts accessing the file system data.

System and method for storage management of file system configuration data

A system, method, and computer-accessible medium for storage management are disclosed. A failure condition is detected in a storage stack comprising a first host and a storage device. Data from the storage device is exported to a plurality of additional hosts. The data is validated using the plurality of additional hosts.

System and method for distributed storage verification

A file system may employ an enhanced or performance-adjusted allocation scheme when storing data to multiple storage devices. A file system may monitor one or more performance characteristics of storage devices. The file system may, in response to storage requests, select one or more of the storage devices for storing data associated storage requests based on differences among the respective monitored performance characteristics for the storage devices. Additionally, the file system may determine an allocation pattern for storing data to the storage devices and may modify the determined allocation pattern based on a detected change in the monitored performance characteristics of the storage devices. Further, the file system may store data based on both the allocation pattern and on data characteristics associated with a data storage request. The file system may also incorporate input specifying either new performance characteristics or a new allocation pattern.

System and method for data storage management. Embodiments may be used to perform analysis of disk-based data storage. Embodiments may provide a storage analysis mechanism for estimating storage inventory/availability risk tradeoff for data storage media for an application or group of applications. Embodiments may be used to generate storage inventory information and recommendations or requirements for pooled and/or non-pooled storage. Embodiments may be used to compare pooled storage to non-pooled storage for a plurality of applications in a storage system.

Data storage analysis mechanism

Systems, methods, apparatus and software can provide the capability of grouping related files together so as to optimize placement of the files on the physical media. Consequently, certain system operations (e.g., backup, defragmentation and the like) can be performed on the group of files, as opposed to a single file or the entire filesystem.
