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 :) D. -------------------------------- Dale Corse System Administrator Wolfpaw Services Inc. http://www.wolfpaw.net (780) 474-4095 > -----Original Message----- > From: Michael DeMan [mailto:michael@staff.openaccess.org] > Sent: Monday, June 02, 2003 10:21 AM > To: Wolfpaw - Dale Corse; Thomas Dwyer; freebsd-isp@freebsd.org > Subject: Re: Mirror Server > > > What is your performance with this?
