The following types of data cannot be restored from ARCserve tapes:
If the ARCserve backup spans multiple tapes, you must have all the tapes that were included in the ARCserve backup available. Make sure you start both the catalog and restore jobs with the first tape used in the ARCserve backup.
To restore data from ARCserve media
During cataloging, Backup Exec reports file formats that it can read. Files that cannot be read do not appear in the catalogs. The media description that appears in the Backup Exec catalog comes from the session description used by ARCserve.
Media-based catalogs are not supported on tapes created by other vendors' backup products. Because of this, cataloging ARCserve tapes takes considerably longer than cataloging a tape made with Backup Exec.
