What is CA VM:Archiver and what problem does it solve?
CA VM:Archiver is a software product designed to reduce disk space usage on z/VM systems by archiving infrequently accessed CMS files. It allows users to easily recall archived files when needed, providing a balance between storage efficiency and data accessibility.
What is the core functionality of CA VM:Archiver?
The core function of CA VM:Archiver is to move CMS files that are not actively used from primary storage to secondary storage (typically tape or disk). This frees up valuable disk space on the z/VM system. Users can later recall these files, restoring them to their original location.
How does CA VM:Archiver keep track of archived files?
CA VM:Archiver uses a catalog to track archived files. This catalog contains metadata about each archived file, including its original location, archive location, and other relevant information. This catalog is crucial for the recall process.
Can you describe the archiving process?
The archiving process typically involves identifying eligible files based on criteria such as last access date, file size, or user-defined rules. Once identified, the files are moved to the archive location, and their metadata is updated in the catalog.
