As far as I can tell, there's nothing wrong with it. It's magic and wonderful. I use it in a cron job (with the "-e ssh" option for security and password-less login) to back up a small business server onto my server. Every 2 hours rsync backs up the financial data (a 1.5MB file in 2 minutes), and once a day it does the entire disk (4GB in 10 minutes or so). > apparently it does a remote diff somehow and then sends only the > parts that need changing? i can't imagine that it's possible to > compare two 1mb text files for differences without at least > sending one across the wires -- yet the manpage certainly has me > thinking that's what they claim it does. hmm? There's a web page describing the algorithm at http://samba.anu.edu.au/rsync/tech_report/node2.html. It's not magic anymore, just wonderful. -- Glenn English [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
