Chapter 16. Bootable backups and
A bootable backup allows you to restore a system from scratch by booting from
the media where the image resides. This implies that the media has a section
which can be read by the bootstrap loader. Therefore, a bootable image enables
you to set up the NAS Gateway 500 as new, even if a new entire system or parts
of the system, such as new disks, are provided.
This might occur, for example, during hard disk failure or human error, when the
problem cannot be fixed with any other method (such as when there is an
accidental delete of important system files from the system). The system
administrator would then need to recover the operating system from scratch
within the shortest time period, and restore the application data back to the
system to resume normal operations.
