Methods, systems, and computer readable mediums for implementing a data protection policy for a transferred enterprise application
Methods, systems, and computer readable mediums for logically remediating infrastructure resource components are disclosed. According to one example, the method includes capturing metadata specifying both a data protection policy applied to an enterprise application supported by a host computing system and a location of backup file data associated with the enterprise application and transferring the enterprise application and the metadata from the host computing system to a target computing system. The method further includes utilizing the metadata to reconstruct the data protection policy for the transferred enterprise application on the target computing system, wherein the metadata specifies a data protection solution for each of a plurality of resource components supporting the transferred enterprise application on the target computing system.
Systems and methods for managing single instancing data
Described in detail herein are systems and methods for managing single instancing data. Using a single instance database and other constructs (e.g. sparse files), data density on archival media (e.g. magnetic tape) is improved, and the number of files per storage operation is reduced. According to one aspect of a method for managing single instancing data, for each storage operation, a chunk folder is created on a storage device that stores single instancing data. The chunk folder contains three files: 1) a file that contains data objects that have been single instanced; 2) a file that contains data objects that have not been eligible for single instancing; and 3) a metadata file used to track the location of data objects within the other files. A second storage operation subsequent to a first storage operation contains references to data objects in the chunk folder created by the first storage operation instead of the data objects themselves.
Load balancing across multiple data paths
Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.
DATA BACKUP USING METADATA MAPPING
An information processing apparatus, backup method, and program product that enable efficient differential backup. In one embodiment, an information processing apparatus for files stored in a storage device includes: a metadata management unit for managing metadata of files stored in the storage device; a map generation unit for generating a map which indicates whether metadata associated with an identification value uniquely identifying a file in the storage device is present or absent; and a backup management unit for scanning the metadata to detect files that have been created, modified, or deleted since the last backup, and storing at least a data block and the metadata for a detected file in a backup storage device as backup information in association with the identification value.
SYSTEM PERFORMANCE LOGGING OF COMPLEX REMOTE QUERY PROCESSOR QUERY OPERATIONS
Described are methods, systems and computer readable media for performance logging of complex query operations.
SECURE DATABASE BACKUP AND RECOVERY
As disclosed herein a computer system for secure database backup and recovery in a secure database network has N distributed data nodes. The computer system includes program instructions that include instructions to receive a database backup file, fragment the file using a fragment engine, and associate each fragment with one node, where the fragment is not stored on the associated node. The program instructions further include instructions to encrypt each fragment using a first encryption key, and store, randomly, encrypted fragments on the distributed data nodes. The program instructions further include instructions to retrieve the encrypted fragments, decrypt the encrypted fragments using the first encryption key, re-encrypt the decrypted fragments using a different encryption key, and store, randomly, the re-encrypted fragments on the distributed data nodes. A computer program product and method corresponding to the above computer system are also disclosed herein.
LOAD BALANCING ACROSS MULTIPLE DATA PATHS
Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.
COMPUTER DATA SYSTEM DATA SOURCE REFRESHING USING AN UPDATE PROPAGATION GRAPH
Described are methods, systems and computer readable media for data source refreshing.
DATA REPLICATION MANAGEMENT
In one example, initiating data replication process to copy source data set as target data sets to a plurality of target devices during a predefined time period, determining progress information regarding completion of the replication process based on historical and current performance information of the plurality of target devices, and if the progress information indicates that the replication process is not to be completed within a predefined time period, then selecting a target device from the plurality of target devices to complete the complete the replication process based on historical and current performance information of the plurality of target devices, and causing the selected target device to continue with the completion of the replication process, causing the non-selected target devices to discontinue with the replication process, and causing the replicated target data set to be copied to another target device of the plurality of target devices.
Block-level single instancing
Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.
