Mirror Server

[Wolfpaw - Dale Corse]

Hmm.. 10 gig in 1/2 hr or so.. its not wonderful, we use
something entirely different for shell servers (we have
20 of them..). This is good for an "internal" machine,
but if your looking for fast backups, use tar with the
update flag.. it works nicely. The nice thing about
rsync is it can reproduce the entire fs as it was,
without some of the problems tar has.. such as having
to have a huge chunk of space so you can tar one
disk, and then untar onto another..

Anyway.. my 2 cents :)
