Creating a Bootable Tape (Without Data)
Use the Create a Bootable Tape (without data) option to create a bootable tape on
the local system or a remote server. This bootable tape is identical to a system
backup except that it does not contain any backup data.
The primary intention of this option is to enable you to create a tape that can be
used to boot a system to the SysBack Installation and Maintenance Menus without
having to perform a full backup. This tape enables the user to perform system
maintenance or to boot from an alternate media if the boot images on a prior
system backup tape are corrupt or do not contain updated device information.
