摘要:
A technique for implementing policy-aware backup and restore capability in a tiered storage system. If a data set's contents are backed up from the tiered storage system to a backup storage system, metadata for the data set may also be backed up. Prior to the data set being restored from the backup storage system to the tiered storage system, the backed up metadata is restored and processed to determine a tier among the tiered storage pools to which the data set will be restored.

Provided are a method, system, and program for managing retention of stored objects. A modification request is received with respect to a stored object. A determination is made as to whether a retention protection mechanism is set and a storage policy associated with the stored object is processed to determine whether the stored object has expired according to the storage policy in response to determining that the retention protection mechanism is set. The modification request is allowed to proceed in response to determining that the stored object has expired.

A policy-based retention manager provides protection and management of files in a WORM file volume. The protection of the files is accomplished by the manager establishing a volume retention period for securely storing the files within the WORM file volume on a WORM media (e.g., a WORM disk media) based on a file retention end date of each file within the WORM file volume, and securely storing the WORM file volume on the WORM media during the volume retention period. The management of the files is accomplished by the manager establishing a volume reclamation period for reclaiming unexpired files within the WORM file volume prior to an expiration of the volume retention period, and reclaiming each unexpired file within the WORM file volume from the WORM media during the volume reclamation period.

A system, method and computer program product are provided for generating backup sets for a specific point in time from backup data stored in a backup storage device. A backup set, in accordance with an illustrative embodiment, is a collection of the files and data that would have been the most recently backed-up version of a computer's files and data at the particular point in time if the backup set had been created at that point in time. In order to generate the backup set, versions of data objects are identified in the backup storage system that have backup timestamps equal to or prior to the designated point in time and that have deactivation times that are after the designated point in time. In addition, a mechanism for deleting versions of data objects based on a retention time and an inactive version limit is provided.

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.

An apparatus for adaptive polling of a monitored system includes a poll receiving module configured to receive a polling signal from a polling system, an event prediction module configured to predict when an operation-related event of a monitored operation will occur in the monitored system, a next polling time determination module configured to determine a next polling time based on the prediction of when the operation-related event will occur in the monitored system and a polling response module configured to communicate the next polling time and monitored system operation information to the polling system. In one embodiment, the next polling time determination module is further configured to determine the next polling time based on the prediction of when the operation-related event will occur and on network traffic.

Novel tools and techniques for automated recovery of information from commercial web portals, including commercial web portals requiring credentials for access. In some instances images are captured and pushed to external processes for improving system performance. In some instances access to automated software agent remote control modules is balanced across a system comprising a plurality of processors hosting the automated software agent remote control modules. Some instances provide provisioning of credentials, in particular indicating credentials available for an unlimited or a select limited number of users and monitoring credential use of those credentials usable by a select number of users. Some instances provide cache management optimizes retrieval of data by external processes and ensures reliability of such data to reduce unnecessary web portal inquiries.
摘要:
A copy procedure detects qualified data objects in a body of source data, and copies the source data to a target storage unit except for unqualified data objects, which are replaced with a prescribed bit pattern. Following completion of the backup, a record is prepared indicating that all data objects exist in the specified target storage, regardless of whether each data object was replaced with a predetermined bit pattern rather than being physically written to the specified target storage. This process may, be repeated in order to perform data reclamation, effectively removing user files no longer qualifying for backup.
摘要:
Provided are a method, system, and program for maintaining active-only copy storage pools. A first storage pool includes at least a first aggregate including a plurality of files. A second aggregate is generated in a second storage pool. A determination is made as to whether files in the first aggregate are active or inactive versions. Active versions of files are copied from the first aggregate to the second aggregate in the second storage pool, wherein the second aggregate does not include inactive versions of files in the first storage pool.
