Reciprocal data storage protection is combined with “N+1” hardware provisioning and on-demand resynchronization to guarantee full data availability without impairing performance. Pairs of nodes are identified that act as backups for each other, where each node stores a secondary copy of data allocated to its reciprocal, paired node. A single extra node is brought online to take over the role of a failed node and assumes the role of the primary node it replaced.

Abstract:
A networked digital data processing system has two or more client devices, a network including a set of interconnections for transferring information between the client devices, at least one of which has a local data file storage element for locally storing and providing access to digital data files arranged in one or more client filesystems. A migration file server includes a migration storage element that stores data portions of files from the client devices, a storage level detection element that detects a storage utilization level in the storage element, and a level-responsive transfer element that selectively transfers data portions of files from the client device to the storage element.

Abstract:
An improved backup storage system and method for use in conjunction with hierarchical or mass storage servers and networks is disclosed. Baseline, full and incremental backup procedures are used to save file copies. In one preferred embodiment, the baseline backup procedure is used to store copies of stable files, i. e. files that are modified less frequently, if at all. With a hierarchical storage server, such files are typically those stored on tertiary storage media, e. g. erasable optical disks, WORMs or magnetic tape. The full backup procedure stores, as full backup copies, copies of all files not in the baseline backup and files that have been changed since the time of their baseline backup. The full backup procedure also stores file identifiers and signal representative of storage locations of baseline backup copies for files which have not been changed since the time of the baseline backup. The incremental backup procedure stores, as incremental backup copies, copies of files not in the baseline or full backups, e. g.

International Classification:
G06F 1200 G06F 1540
US Classification:
395600
Abstract:
A digital data storage apparatus has primary, secondary and backing storage elements characterized by respectively longer access times. A level detector signals when the quantity of data in the secondary store exceeds a threshold amount. A data migrator responds by moving selected data files from the secondary store to the backing store. The apparatus also includes a baseline back-up element that stores archive copies of a set of selected data files. A full back-up element stores archive copies of those files that, (1) were originally copied to the baseline back-up set but have since changed, or (2) are not otherwise within the baseline back-up set. For those files which were originally copied to the baseline back-up set and which have not changed, the full back-up element stores pointers indicating locations of the respective files in the baseline back-up set.

Abstract:
Systems and methods for creating a live copy of a data object from a production system for use by third party applications. The systems and methods include receiving at least one request for a copy of production data from an application; creating a live backup copy; creating a flash copy of the live backup copy, and a flash copy bitmap; creating a modified version of the live backup copy by changing a subset of data in the live backup copy; recording the changed subset of data using the flash copy bitmap; mounting, the modified version of the live backup copy to the application; and transforming the modified version of the live backup copy back to the live backup copy when unmounting the modified version of the live backup copy of the production data from the application by applying changes associated with the flash copy bitmap to the live backup copy.

International Classification:
G06F 11/14 G06F 17/30
Abstract:
Systems and methods of enabling a service level agreement to specify interactions between an application and a remotely located object store that manages data as objects. A computing device receives data associated with a request to write application data to an object store according to a schedule, wherein the data is file system data. The computing device creates a snapshot associated with the requested application at a snapshot pool, and transmits instructions to a cloud formatting engine to create a virtual disk at a storage pool associated with an object store. The computing device copies the snapshot from the snapshot pool to the virtual disk, the snapshot comprising file system data and transmits instructions to the cloud formatting engine to convert the data associated with the first snapshot into an object, and move the object from the virtual disk to the object store.

A block away, Tracy Taylor told a gathering of friends how he survived inside his pickup. The winds and flying debris battered the vehicle so violently that he didn't notice that a large oak tree had crashed down onto the cab. "I put the bag over my head and just rode it out," he said.

We feel terrible that this happened," said Tracy Taylor of Kingston, who attended Sanborn Regional High School with Lanza.
