Boot on DAT

Hello

I need to find a way to restore a doc/web server with a bootable DAT
The idea is to tar or rsync on /dev/st0 (DAT device) the content of all 
my drive parts. Then create a boot to put on the DAT, and a post-login 
script asking for the restore.

   - What's the best to use ? tar or rsync (tar has also only update 
options, and I know better about it)

   - Can I use an image of a boot-floppy and put it on the DAT

   - I can eventually restore with cdrom images, but  dont't know how to 
create a bootable cd (don't have a cd burner on my linux box, but can 
get one)

Thanks
