    摘要: A method is used in managing data on data storage systems. Rules are defined for candidate data unit selection. The rules are automatically executed on a primary data storage system to examine data units on the primary data storage system. The rules are applied to the data units. A data unit is identified that matches the rules and the identified data unit is migrated. The identified data unit is copied from the primary storage system to a secondary storage system. The identified data unit on the primary storage system is replaced with metadata. the data storage space in the primary storage system corresponding to the identified data unit is freed up.

    摘要: For migration or de-duplication of a file system having a large number of files, a utility program traverses the file system to create a log of file-specific information about the file system. For identification of duplicates, the utility program produces a signature for each file. Respective instances of the utility program are started on multiple nodes upon which the file system is mounted. A fully qualified pathname is compiled during transfer of the log to a database. Multiple databases can be produced for the file system such that each database contains the file-specific information for a specified range of inode numbers. The database also maintains classification state for each file. For example, for a migration or replication process, the classification state identifies whether or not the file has been untouched, copied, linked, secondary-ized, source deleted, or modified.

    摘要: (N+Q) dimensions of data can be analyzed in an N-dimensional native OLAP cube by submitting an (N+Q)-dimensional custom query and converting the (N+Q)-dimensional custom query into an N-dimensional query for submission to the N-dimensional native OLAP cube. An N-dimensional result of the N-dimensional query is provided and converted into an (N+Q)-dimensional result of the (N+Q)-dimensional custom query. The (N+Q) dimensional result is then provided as an answer to the (N+Q) dimensional custom query.
