摘要： A computer-implemented method includes receiving custom metadata for several data items, the data items having system metadata associated therewith, selecting, based on the custom metadata, some of the data items to move between a primary storage system and a secondary storage system, and moving the selected data item(s) between the primary storage system and the secondary storage system. A computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer to cause the computer to perform the foregoing method. A system includes a processor and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to perform the foregoing method.

摘要： The embodiments deal with files that are already present in a storage when mounting the storage in a file system and files created after the mounting as different groups. (Metadata of) the files is classified. The files are each divided into metadata (index) and a file main body and are recorded on different storage areas, that is, an index partition (IP) and a data partition (DP), associated with each other. This file system is effective in a storage format in which a new file is merely written and an already written file is not updated or deleted (for example, a tape medium used in the LTFS). The embodiments implement a WORM file system by rejecting a request to update or delete a file that is present at mounting as a WORM file and permitting update or deletion of a file that is created after mounting until the storage is unmounted.

摘要： A system and method for data co-location in hierarchical storage management (HSM) system are presented. Related data units may be grouped to be collectively accessed from a plurality of data units stored on a first sequential media. The related data units may be migrated from the first sequential media in the HSM system to a second sequential media in the HSM system to sequential and continuous access to the related data units on the second sequential media.

摘要： According to an aspect of the present invention, there is a method, computer program product and/or system for storing data that performs the following operations (not necessarily in the following order): (i) receiving a request to migrate a data file from primary storage to secondary storage; (ii) invoking a primary data extraction function, registered by a user, to determine primary data for the data file; and (iii) inserting the primary data into a stub file.

摘要： An approach, for storing video data in a plurality of tape media via a ring buffer. A tape data splitter receives video data stored in a ring buffer. The tape data splitter writes the video data to a current tape media. The tape data splitter detects an end of tape media event. The tape data splitter responds to the end of tape media event, by switching the current tape media to a next tape media. The tape data splitter selects a resume point for the video data stored in the ring buffer and writes to the next tape media, the video data stored in the ring buffer that is subsequent to the resume point.
