If you do it all at once, at least.

I have "live" mirroring of my disks - all disk writes are mirrored over
the net in real time to images on a big backup drive on another
machine. (Or near-real-time, if the writer is producing data faster
than the mirroring can deal with it - the software goes to some lengths
to handle that case well.) It doesn't cause load problems in normal
use because the network load it imposes is spread out throughout the
day, becoming visible only when doing a data transfer over the net to
disk from a source that can run the network at least half-wide-open.

(Yes, I know it's not a comprehensive backup solution. It doesn't deal
with "oops, I didn't mean to delete that file", or "now what was in
this file last May?", but it's not intended to; it's designed to defend
against "this disk spindle just went casters-up", and it does that very
well. I've had two disk deaths since I started doing it, and it did
its job perfectly each time.)
