The present invention relates to a method, system, and computer program product for determining storage device weight values to use to select one of the storage devices to use as a target storage to which data from a source storage is migrated. A determination is made, for each of the storage devices, of static parameter values for static parameters comprising attributes of the storage device and dynamic parameter values for dynamic parameters providing device health information determined by accessing the storage device to determine operational conditions at the storage device. Storage device weight values are determined as a function of the static parameter values and the dynamic parameter values of the device. The determined storage device weight values are used to select one of the storage devices as the target storage to which data from the source storage is migrated.

Determining weight values for storage devices in a storage tier to use to select one of the storage devices to use as a target storage to which data from a source storage is migrated

Methods, systems, and computer program products are provided for optimizing selection of files for eviction from a first storage pool to free up a predetermined amount of space in the first storage pool. A method includes analyzing an effective space occupied by each file of a plurality of files in the first storage pool, selecting one or more of the plurality of files as one or more candidate files for eviction, based on the identified one or more data blocks, and evicting the one or more candidate files for eviction from the first storage pool to a second storage pool.

Methods and systems for data cleanup using physical image of files on storage devices

Systems and methods for image deduplication in a file are provided. A method includes identifying a plurality of similar images (e.g., similar intent images) in an electronic document. The method also includes designating one of the plurality of similar images as a master copy. The method also includes replacing each remaining one of the plurality of similar images, other than the master copy, with one of (i) a duplicate copy of the master copy and (ii) a soft link pointing to the master copy.

Deduplicating similar image objects in a document

Methods and systems for enhancing reliability in deduplication over storage clouds are provided. A method includes: determining a weight for each of a plurality of duplicate files based on parameters associated with a respective storage device of each of the plurality of duplicate files; and designating one of the plurality of duplicate files as a master copy based on the determined weight.

Systems and computer program products are provided for optimizing selection of files for eviction from a first storage pool to free up a predetermined amount of space in the first storage pool. A method includes analyzing an effective space occupied by each file of a plurality of files in the first storage pool, identifying, from the plurality of files, one or more data blocks making up a file to free up the predetermined amount of space based on the analysis of the effective space of each file of the plurality of files, selecting one or more of the plurality of files as one or more candidate files for eviction, based on the identified one or more data blocks, and evicting the one or more candidate files for eviction from the first storage pool to a second storage pool.

Systems and computer program products are provided for optimizing selection of files for deletion from one or more data storage devices to free up a predetermined amount of space in the one or more data storage devices. A method includes analyzing an effective space occupied by each file of a plurality of files in the one or more data storage devices, identifying, from the plurality of files, one or more data blocks making up a file to free up the predetermined amount of space based on the analysis of the effective space of each file of the plurality of files, selecting one or more of the plurality of files as one or more candidate files for deletion, based on the identified one or more data blocks, and deleting the one or more candidate files for deletion from the one or more data storage devices.

Implementing calendar-based power reserve includes identifying a new calendar entry scheduled into a calendar application of a mobile communications device. The new calendar entry specifies a telephone call. Upon determining a priority indicator has been set for the new calendar entry in the calendar application, the calendar-based power reserve also includes directing a power management component of the mobile communications device to reserve an amount of power for the telephone call, and updating a battery power indicator on the mobile communications device to reflect a capacity of a battery of the mobile communications device. The capacity reflects a current amount of available power for the battery minus the amount of power to reserve.
