Rabbit-5 is certainly FASTER than VMS BACKUP.  In fact, it also uses less tape
than VMS BACKUP.  This is because Rabbit-5 does not compute CRC or write
redundancy blocks on the tape.

You can also make VMS BACKUP run just as fast by using /NOCRC/GROUPS=0 (I think
that's right).  Boy does it go fast.

However!  Backup speed is secondary to the real goal, which is a reliable
backup of the data.  I would never use a product such as Rabbit-5 for my
backups, just as I would never turn off VAX BACKUP's redundancy features.  This
is because tapes just are not reliable enough for our needs without these
special features.

But if I did want to run a "quickie" backup, I would still use VAX BACKUP and
turn off CRC and redundancy blocks, rather than buying a separate product.
