I can confirm that.  I manage 3 installations of amanda server and in
2 of them I have a secondary backup system of the server using
storeBackup.  My home installation of amanda is a machine with 3 disks
of 4TB.  The first have all the system data and my personal files, the
others 2 disks contains the vTapes and the backup files of
storeBackup.  With this setup I can survive the loss of a single

Being the 3 disks always online, I am not protected against a virus
or a sysadmin error that can wipe the data in the 3 disks with one
single command.
