Abstract: Techniques for reducing false recalls by controlling recalls performed by data migration applications in a storage environment comprising a plurality of storage units. According to an embodiment of the present invention, false recalls are reduced by restricting certain users, groups, and programs from performing recall or demigration of data. Techniques are provided that enable a storage system administrator to specify a list of users, groups, and programs for which data file recall is disallowed.

Abstract: Automated techniques for storing data in a data storage environment. Techniques are provided for determining storage locations for data in a heterogeneous storage environment based upon storage policies configured for the storage environment. The data is stored in storage locations that enable efficient data access while optimizing the use of available storage resources with minimum human intervention.

Abstract: Techniques for automatically performing various data and storage management operations in a storage environment. The operations to be performed are automatically determined based upon policies configured for the data and storage environment. For a selected operation, one or more files on which the operation is to be performed are also automatically determined. The one or more files may be selected using different techniques based upon characteristics of the files and also based upon the operation to be performed. Target storage units, if need for the operation, are also automatically determined. The operations are then performed on the selected files. Examples of policy-driven operations include copying a file, moving a file, deleting a file, archiving a file, backing-up a file, restoring a file, migrating a file, recalling a file, etc.

Abstract: Techniques for facilitating backup and restore operations in a storage environment comprising migrated files. Backup and restore operations on migrated files are performed without triggering recall while maintaining data integrity.

Abstract: Techniques for performing operations on migrated files without triggering a recall of the migrated data. For example, embodiments of the present invention can perform a copy, move, or delete operation on a migrated file without recalling the migrated data associated with the file.

Abstract: Techniques for maintaining data consistency in a storage environment. In a HSM controlled storage environment, techniques are provided for automatically detecting and correcting inconsistencies after a file system or a portion thereof has been restored from backup. The file system may store data files, tag files, and/or repository files that have been restored from backup.

Abstract: Techniques for balancing capacity utilization in a storage environment. Embodiments of the present invention automatically determine when capacity utilization balancing is to be performed for a group of storage units in the storage environment. A source storage unit is determined from the group of storage units from which data is to be moved to balance capacity utilization. Utilized-capacity balancing is performed by moving data files from the source storage unit to one or more target storage units in the group of storage units. The storage units in a group may be assigned to one or more servers.

Abstract: Techniques for moving a stub file (or any information that is used to recall migrated data) from an originating storage location to a destination storage location without recalling the migrated data corresponding to the stub file. The originating storage location and the destination storage location may be on storage unit allocated to the same server or allocated to different servers.

Abstract: Techniques for optimizing capacity utilization among multiple storage units based upon costs associated with storing data on the storage units. Embodiments of the present invention automatically determine when data movement is needed to optimization storage utilization for a group of storage units. According to an embodiment of the present invention, in order to optimize storage utilization and storage cost, files are moved from a source storage unit to a target storage unit that has a lower data storage cost associated with it than the source storage unit. The storage units may be assigned to one or more servers.

Abstract: Embodiments of the present invention are directed to a system and a method for defining policies that can be used in various types of management applications for automating and performing one or more actions on at least one resource in a computer network environment. The system is configured to receive a signal indicating occurrence of a monitored event; identify rules having first conditions that are based upon the monitored event; and identify one or more rules from the rules having the first conditions for which the first conditions are satisfied. The one or more rules define one or more actions to be performed upon satisfying one or more second conditions based upon one or more non-monitored attributes of at least one resource. At least one rule is identified from the one or more rules for which the one or more second conditions of the at least one rule are also satisfied. The one or more actions to be performed for the at least one rule are defined, and are performed on the at least one resource.

Abstract: Techniques for restoring data in a heterogeneous storage environment. The data to be restored may be identified based upon user-specified contents and/or attributes of the data. The data to be restored may be identified from backup data, archived data, and other types of data. A single search-oriented uniform user interface is provided to restore data irrespective of the storage location of the data. Access to data regardless of the location and type (e.g., archived, backup, or otherwise) of the data is enabled.
