I've got an installation of FreeBSD 4.4 Stable running along quite nicely.
   Now I'm trying to design a backup system for it.

This installation is mainly a personal server.  It's running on a Seagate 
IV ATA HD, and it is a low-access server.  It runs my personal mail, and my 
personal web site.

I have a second identical HD that I'm intending to set up a nightly dump to.

My questions:

- Is that a decent backup scenario?

- Is there a good reason I should use a tape drive instead?

- Should I use something other than dump?  I want to make as accurate a 
running backup as possible.  Ideally the backup should preserve the exact 
state of my server at the moment of backup.  Does it make sense to create 
a bootable copy instead of a dump file (i.e. a dump | restore)?

- Does it make sense to mount/unmount the backup HD as part of the backup 
routine, so that it will not be evident to a hacker?

Thanks!
