20110055164 | METHOD AND SYSTEM FOR MAINTAINING DATA RECOVERABILITY - A method and system for maintaining data recoverability of a computer system coupled to a storage device storing data objects includes identifying at least one recoverability parameter associated with the storage device. A recoverability index is calculated based on a recoverability parameter. The recoverability index may reflect the recoverability of the computer system from data loss. The recoverability index may be continuously calculated and evaluated. Recoverability actions, such as performing a backup operation, may be performed in response to a value associated with the recoverability index. | 03-03-2011 |
20120158665 | SYSTEM RESET AND SYSTEM RESTORE - Some embodiments of the invention provide techniques for performing system reset and/or system restore operations. Some embodiments store a record of any changes performed to a data file stored on a virtual hard disk using differencing virtual disks that are captured over time. To restore the file to the state in which it existed at any particular point in time, embodiments of the invention may allow for rolling back the system to a differencing virtual disk captured at or before that time and setting aside blocks of the differencing virtual disk chain captured after that point. To perform a system reset, the system may be rolled back to the parent virtual hard disk, by setting aside all of the blocks of the differencing virtual disk chain. Some embodiments of the invention provide for separating information on the system into a plurality of entities, and maintaining a separate set of differencing virtual disks for each entity. For example, some embodiments may create an entity may be created for each of the operating system, applications and user data, and maintain differencing virtual disks for each over time. | 06-21-2012 |
20150127618 | Sharing of Snapshots among Multiple Computing Machines - A solution is proposed for managing each one of a plurality of computing machines. A corresponding method comprises taking one or more snapshots of the computing machine or part thereof, the snapshots being organized in a snapshot tree of nodes representing the snapshots according to a dependency thereof, expanding the snapshot tree of the computing machine according to each sub-tree of the snapshot tree of each other computing machine having the snapshot of a parent node of the sub-tree matching a graft node of the snapshot tree of the computing machine, the sub-tree being appended to the graft node, selecting a snapshot of the other computing machines represented by a selected node of the snapshot tree of the computing machine, and restoring the selected snapshot on the computing machine. | 05-07-2015 |
