    Abstract: A method includes receiving a request to save a first file as immutable. The method also includes searching for a second file that is saved and is redundant to the first file. The method further includes determining the second file is one of mutable and immutable. When the second file is mutable, the method includes saving the first file as a master copy, and replacing the second file with a soft link pointing to the master copy. When the second file is immutable, the method includes determining which of the first and second files has a later expiration date and an earlier expiration date, saving the one of the first and second files with the later expiration date as a master copy, and replacing the one of the first and second files with the earlier expiration date with a soft link pointing to the master copy.

    Abstract: A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to optimize data remanence over hybrid disk clusters using various storage technologies, determine one or more data storage technologies accessible by a file system, and determine secure delete rules for each of the one or more storage technologies accessible by the file system. The secure delete rules include a number of overwrites required for data to be securely deleted from each of the one or more storage technologies. The programming instructions are further operable to provide the secure delete rules to the file system upon a request for deletion of data for each of the one or more storage technologies a specific amount of times germane to secure delete data from the one or more storage technologies.

    Abstract: Various embodiments providing a framework for Quality of Service (QoS) within and between globally distributed computing components by a processor. At least one resource required for a computing process is estimated by examining information associated with a resource template. A storlet is allocated as the at least one resource at a storage node, thereby offloading computing elements to at least one storage unit. The allocated storlet performs the computing process according to constraints delineated by the resource template.

    Abstract: In accordance with one embodiment of the present description, a logical file unit containing a set of data stored in cache or other memory and mapped by a reference pointer to a physical file unit in a storage, may be overwritten with new data in the memory without first read/write copying the data in memory to a new logical file unit in the file system. Instead, the original physical file unit of data in the storage is preserved and the original reference pointer for the original physical file unit of data may be used to map a new logical file unit in the file system to the original physical file unit storing the original set of data. Other aspects are described.
