It works also with external HDs.
And mapped network drives and if the backup file isn't too big, you can get
it onto CDR in a mapped cd burner.
I guess what I really should have said is the best thing about the program
is it's free. Other than that, it's really not a great backup program. And
while it can do a full system backup, that feature is very clumsy to use.
There are so many other programs out there that work with all types of
common hardware (and at reasonable prices) that it just doesn't make sense
to struggle with this application. Especially, when it comes to full system
backup, I firmly believe that a few dollars for a third party solution are
dollars well spent. It's easier to stick to a regular backup schedule when
the program being used is "friendly" and easy to use.
