Abstract: In one embodiment, a method includes replicating a production volume on a plurality of replica volume portions. Each replica volume portion is stored on a respective storage array with a respective journal. The replicating includes distributing data from a write command to a production volume across the replica volume portions using a coding scheme. A subset of replica volume portions, less than a total number of replica volume portions, includes data for a full replica volume of the production volume.

Abstract: In one aspect, a method includes migrating a database object from a source database to a target database, updating a storage of the location of the DB object to be the target database, directly accessing one of the target database and the source database during the migrating and executing, during the migrating, a database command by retrieving the DB object from the other one of the target database and the source database.

Abstract: A bug or problem that occurs during execution of an application is detected and a time at which the problem occurred is stored. An enhanced copy of the application is restored from before the time at which the problem occurred, and the enhanced copy of the application is run. If the problem is reproduced, the application is paused. If the problem is not reproduced, restoration of the enhanced copy, running of the enhanced copy and detection of the problem are repeated for a pre-designated number of times.

Abstract: In one example, a method includes generating an enhanced copy, which includes application data generated from using an application, the application, a configuration of the application and runtime settings to run the application. The method also includes restoring at least one of the application, the configuration of the application and the runtime settings using the enhanced copy.

Abstract: According to one embodiment, a request is received for estimating migrating a first dataset from a first cloud system to a second cloud system. A migration cost estimation module determines a network bandwidth required to migrate the first dataset from the first cloud system to the second cloud system, determines a duplicated data time period during migration that the first dataset has to be maintained by both the first cloud system and the second cloud system for service continuity, and determines a total cost of migrating the first dataset from the first cloud system to the second cloud system based on the required network bandwidth and the duplicated data time period. It is then determined whether to migrate the first dataset from the first cloud system to the second cloud system based on the total cost.

Abstract: In general, the invention relates to a method and system for migrating tables in databases. The method may include calculating a first plurality of migration factors for a first set of tables in a source database using a plurality of pre-calculated factors and a first plurality of dynamically-calculated factor, where each of the first plurality of migration factors is associated with one of the first set of tables. The method may further include selecting a first table from the first set of tables to migrate based on the first plurality of migration factors; and migrating the first table to a target database.

Abstract: In one embodiment, a method includes measuring a first parameter associated with copying a storage entity to a first backup site, measuring a second parameter associated with copying the storage entity to a second backup site and determining a replication mode to copy the storage entity to the first backup site and a replication mode to copy the storage entity to the second backup site in response to a replication policy and the first and second parameters measured.
