A computer-implemented method, according to one embodiment, for creating a backup copy of a deleted file based on a previous backup copy of the file to be deleted includes creating a deleted data set record associated with a file in association with deletion of the file, wherein the file comprises a file data set. The file data set is removed from a catalog containing the file data set. The method includes freeing physical space associated with the file data set and extracting the file from a most recent backup copy and writing the file to a temporary file in a pre-defined pool space. A file level backup copy is created of the temporary file based on the deleted data set record, and the temporary file and the deleted data set record are deleted.

Non-impactful backup of a deleted data set

A host system communicates to a production system that performs point-in-time copy operations to a backup system to generate a logical corruption protection (LCP) copy of a production copy that comprises a data set, wherein the point-in-time copy operations perform copying at a media level in which physical tracks are copied from the production system to the backup system, and wherein the point-in-time copy operations avoid using information on the data set or file structure that is included in a media on which the data set is stored. In response to a detection of a logical corruption in the data set, a recovery application executing in the host system recovers the data set from the LCP copy.

Data set recovery from a point-in-time logical corruption protection copy

Provided are a computer program product, system and method for data storage volume record management for application-level recovery in accordance with the present description. In one embodiment, logical volume movement is addressed when performing enterprise application recovery. In one embodiment, a host-based recovery product in accordance with the present description, can detect logical volume movement from one physical device to another and proactively prevent application level recovery that potentially may result in data loss. In one embodiment, a time-based capturing of pairings of logical and physical volume identifiers or descriptors within storage configuration records and sub-records are used to surgically recover volumes of an application from enterprise level protection copy of physical media. This history of pairings facilitates many types of logical volume to physical media remapping, such as the regular migration of data to replacement storage controllers which can occur at various times.

Data storage volume record management for application-level recovery

Provided are a computer program product, system, and method for archiving data sets in a volume in a primary storage in a volume image copy of the volume in a secondary storage. A volume image in the secondary storage is created comprising a copy of the volume in the primary storage. For each of a plurality of data sets in the volume, data set level archive operations are performed comprising, determining from metadata for the data set whether an archival policy criteria is satisfied, requesting an exclusive lock to the data set, and in response to obtaining the exclusive lock and determining that the archival policy is satisfied, updating a directory for the data set to indicate that the data set is archived in the volume image.
