Depending on your site's restore requirements and how long you need to have catalogs available, it may be more useful to retain condensed catalogs than to discard them. If a domain-level catalog is available, CA VM:Backup processes only those tapes that contain data for the minidisk, file space, or directory being restored. If no catalog is available, CA VM:Backup requests that one tape from each backup job be mounted before restore processing begins to obtain information about proper tape sequence; these tapes may need to be mounted a second time when CA VM:Backup begins restoring data.
