Abstract: The present invention provides a system and method for creating and accessing a copy of one or more host-accessible storage entities contained in a persistent consistency point image (PCPI) of a volume served by a storage system. The storage entity may comprise a file system, logical volume, volume group, or “file system on raw device”. The copy of the storage entity is generated using a logical unit number (lun) copying technique in conjunction with a PCPI table of contents (PTOC). The PTOC contains data describing contents of the PCPI, including luns of the storage entity. The PTOC is written to the volume of the storage system, which is configured to store the luns, i.e., in the context of an active file system, immediately prior to generation of the PCPI. After generation of the PCPI, the PTOC is deleted from the volume such that it is only stored within the PCPI and not within the active file system.

Abstract: The subject matter described herein relates to software routines called application exits that are provided at well defined phases of a tenant copy process. The tenant copy process enables copying of separated tenant data associated with a source tenant at multi-computing tenant system to a new created tenant at a destination location either at multi-computing tenant computing system or second multi-computing tenant computing system. The application exits perform predefined functions at the well defined phases such that the predefined functions enable operations including detachment of tenant data from the source tenant that needs to be copied or moved such that the detached tenant data is separated tenant data. When the source tenant is just being moved, instead of being copied, from a source location to a destination location, the source tenant is deleted once all the data associated with the source tenant has been moved to the destination location.

In order to distinguish stub files representing migrated replication data from replicated stub files, priority tags or like identifiers can be used. Thus, when accessing a stub file on the destination system, such as to modify replication data or perform a restore process, the tagged stub files can be used to recall archived data prior to performing the requested operation so that an accurate copy of the source data is generated.
