A system and method for efficiently restoring data to a different computing device. At least a backed up operating system (OS) and an initial file system, which is also referred to as a temporary file system, are restored on a memory connected to a target computing device. The OS and the initial file system are configured for a hardware configuration for a source computing device different from a hardware configuration for the target computing device. The input/output (I/O) modules used for accessing storage devices connected to data storage interfaces within the target computing device are identified and compared to I/O modules in the initial file system. The missing I/O modules in the initial file system for the target computing device are retrieved from the restored OS and inserted in the initial file system. Afterward, a boot up sequence is executed using the modified initial file system.

A method of operating a distributed storage system, the method includes identifying missing chunks of a file. The file is divided into stripes that include data chunks and non-data chunks. The method also includes identifying non-missing chunks available for reconstructing the missing chunks and reconstructing missing data chunks before reconstructing missing non-data chunks using the available non-missing chunks.

A memory device includes a memory cell array including a plurality of memory cells; a counting circuit configured to obtain a counting result by performing a counting operation on data read from the plurality of memory cells; and a control logic configured to perform a data restoring operation based on the counting result without involvement of a memory controller.

Techniques for recovering from session failures between clients and database servers are described herein. A first session may be established between a client and a first database server to handle a database query for the client. A request for data associated with the first session may be received by the first database server from the client, and the data retrieved. Prior to responding to the request, the data is spooled to a first session state stored in a repository made accessible by at least one computing device. The computing device(s) controls access to session states in the repository that correspond to sessions between clients and database servers. The computing device(s) enables sessions to be reestablished between the clients and database servers by accessing data of the session states in the repository and transmitting the data in response to messages received from the database servers containing session identifiers.

During a data protection operation, a system exploits a virtual hierarchy to centralize the configuration and management of operating system credentials of numerous virtual guests. For each virtual guest, the system uses the credential to collect a single Globally Unique Identifier (GUID) previously generated and stored in-guest by any data protection agent. The system stores the collected GUID as a custom property in the context of the virtual hierarchy. The system also exploits the virtual hierarchy custom properties to determine if GUIDs are copies due to virtual guest replication. The system ensures GUID uniqueness by requesting regeneration of the GUID by in-guest data protection agents. Using GUIDs that are unique across the virtual hierarchy, the system can correlate application data of multiple in-guest data protection agents.

An apparatus includes an error read flow component resident on a memory sub-system. The error read flow component can cause performance of a plurality of read recovery operations on a group of memory cells that are programmed or read together, or both. The error read flow component can determine whether a particular read recovery operation invoking the group of memory cells was successful. The error read flow component can further cause a counter corresponding to each of the plurality of read recovery operations to be incremented in response to a determination that the particular read recovery operation invoking the group of memory cells was successful.

A storage system and method for recovering data corrupted in a host memory buffer are provided. In one embodiment, a storage system is provided comprising a non-volatile memory and a controller in communication with the non-volatile memory. The controller is configured to receive a logical-to-physical map from a volatile memory of a host for storage in the storage system's non-volatile memory; determine if there is an error in an entry in the logical-to-physical map; in response to determining that there is no error in the logical-to-physical map, store the logical-to-physical map in the non-volatile memory; and in response to determining that there is an error in an entry in the logical-to-physical map, attempt to recover the entry from a location in the storage system before storing the logical-to-physical map in the non-volatile memory. Other embodiments are provided.

An object of the present invention is to provide a system capable of preventing data from being lost even in the case where upload of the data has failed and of preventing saved data from being deleted without a user knowing it. The present invention is a system that saves data in a storage server and the system includes: a determination unit configured to determine whether or not upload of the data to the storage server has succeeded; a saving unit configured to temporarily save the data in the case where the upload has failed; a notification unit configured to notify a user of that the temporarily saved data exists in the case where the saving unit temporarily saves the data; a retry unit configured to try reupload of the temporarily saved data to the storage server; and a deletion unit configured to delete the temporarily saved data in the case where the reupload has succeeded.

A flash memory device includes a flash memory configured to store a plurality of pages and a control circuit coupled to the flash memory. The control circuit is configured to retrieve data from a page of the flash memory, determine a number of zeroes or ones of the retrieved data, determine whether the number is between a first value and a second value, and determine that the retrieved data has one or more errors based on determining that the number is not between the first value and the second value.

A method and system of checkpointing single process application groups and multi-process application groups. In an exemplary embodiment, the method may include creating at least one full checkpoint for each application in an application group, and creating at least one incremental application checkpoint for each application in the application group. Further, each of the at least one incremental application checkpoint may be automatically merged against a corresponding full application checkpoint. Further, checkpointing may be synchronized across all applications in the application group. In the exemplary embodiment, each application may use both fork( ) and exec( ) in any combination.
