    If a Verify goes through successfully, it means the data on tape is the same as the data on disk, and bar a physical tape failure, you should be able to recover your data.

    Actually, in BackupExec speak, this is not true

    All that verify does is read the backup media  (tape, bkf file) and compute a checksum, then compare the checksum to  one written on the media.  If the checksums match, then the media "Verifies"

    It doesn't really make any sense to compare backup media to disk media on a 24/7 server, since in all likelyhood at least some of the files will have changes between backup and verify
