Abstract: The present invention includes one or more clients in communication with a server. The client desires to send a storage construct to the server for storage. The client negotiates a transmission key with the server. The client generates a storage key associated specifically with the storage construct. The client encrypts the storage construct using the storage key and encrypts the storage key using the transmission key. The encrypted storage construct and encrypted storage key are sent to the server. The server decrypts the storage key using the transmission key. The server stores the storage construct on a storage device separate from a storage device storing the storage key. Preferably, any changes to the storage construct location, the storage key location, or the storage construct name are tracked and proper modifications are made to an association relating the location of the storage construct and the location for the corresponding storage key.

Abstract: Provided are a method, system, and article of manufacture wherein one client node is selected from a plurality of client nodes. A determination is made that an object corresponding to a client node has to be stored. A determination is made as to whether the object has already been stored in the server node by the one selected client node. The object is stored at the server node, in response to determining that the object has not already been stored in the server node by the one selected client node.

Abstract: Provided are techniques for storing local versions of a data set. A first number that indicates how many local versions of the data set are to be stored in local storage given an amount of available local storage is received. It is determined whether a second number that indicates a total number of local versions of the data set that the local storage is capable of storing exceeds the first number. In response to determining that the second number exceeds the first number, the amount of local storage that is capable of storing the first number of local versions of the data set is used.

Abstract: A data processing system for providing archiving of individual mail content while maintaining a single copy mail store can include a mail application enabled to maintain a single copy mail store, a primary data store configured for high data throughput and acting as a single copy mail store for the mail application, and a secondary data store configured for mass storage and having a lower data throughput than the primary data store. The system further can include at least one archive implementation of an archive interface, the archive interface defining an archive task and a restore task. In one aspect of the embodiment, the system can include each of a content table, a content map table and a restore queue. Furthermore, the system can include a map view of archived content for a specified user, the map view providing a user interface for activating the restore task.

Abstract: The present invention provides for a method and system for the disposition of tasks which failed to run during their originally scheduled time. The determination of whether to run missed or delayed tasks is based on calculated ratios rather than on fixed window sizes. A Lateness Ratio is calculated to determine if the time elapsed between the missed task and the scheduled run time is small enough to still allow a late task to run. A Closeness Ratio is calculated to determine if the next available run time for the missed task is close enough to the next scheduled execution of the task that the missed task will be run in place of the upcoming scheduled task. Each ratio is compared to a user defined ratio limit, so if the calculated ratio does not exceed the limit, then the missed task is executed at the first available opportunity.

Abstract: Provided are a system, an article of manufacture, and a computer program product, wherein a first set of backup data is stored in a first computational device and a second set of backup data is stored in a second computational device. Metadata corresponding to the first set of backup data is maintained in the second computational device. The first set of backup data is reconciled with the second set of backup data based on the metadata.

Abstract: Provided are a method, system, and program for generating and indicating incremental backup copies from virtual copies of a data set. A virtual copy operation is initiated to create a virtual copy of a data set, wherein the virtual copy represents the data set at a point-in-time copy, and wherein the virtual copy is completed without transferring the data set to a backup location. An incremental backup operation is initiated with respect to an identified virtual copy, wherein the incremental backup operation copies changes to the data set that occur since a most recent creation of an incremental backup set.

Abstract: Systems and methods are disclosed for providing a federated backup involving the coordination and synchronization of backup and restore operations among a plurality of hosts to ensure data consistency. A master node (backup host) acts as the initiator, coordinator, controller, and possibly as primary console for the entire backup and restore operation. All other worker application hosts and/or worker backup hosts operate as worker nodes and perform various backup and restore steps as directed by the master node. Centralized error handling aborts or recovers the entire backup operation in the event of failure on any one node. In addition, a logical view of the data is provided such that the backup can be managed as one entity, while backing up the data of each node. The backup workload may also be distributed to any other dedicated worker backup hosts (nodes) in order to minimize the impact to the production environment.

A backup group is created and a plurality of backup objects are added as members of the backup group in separate backup transactions. The backup objects added to the backup group are stored to backup storage.

Abstract: A system, method, program, and data structure for performing a backup operation of a target file. At least one operation is initiated to perform at least one delta backup of the target file to at least one delta backup set. A delta backup set includes changes made to a version of a full backup set of the target file generated at a first time, such as an incremental or differential backup operation. The at least one delta backup set is assigned a name component indicating the version of the full backup set generated at the first time subject to the delta backup and an operation is initiated to perform a full backup of the target file to a version of the full backup set at a second time. The second time follows the first time. A determination is made of all delta backup sets having the name component indicating the version of the full backup set generated at the first time during the full backup operation at the second time.
