Firstly let me say that I'm not sure if this is the right list to post to, so if I am incorrect I apologise. Also if there is a better list for me to post to, please direct me to it. I have built a redundant freeBSD box for my mail server, and for my webserver, and am putting the redundant boxes in a different geographic location. I am looking for a way to backup the relevant data on the current mail and webservers to the new redundant boxes every night. I could use scp and do a full backup every night but I remember hearing of a piece of bsd software that can compare the two file systems and just copy the changes. This would dramatically cut down on the traffic across the link between the machines. Is there a tried and trusted method of doing this? BTW I perform backups at the current site onto tape and will continue to do so, I may perform tape backup at the new site too. Is this over kill? Brian

Just go for incremental backups with dump/restore or use rsync.> Firstly let me say that I'm not sure if this is the right list to post to, > so if I am incorrect I apologise.

Unison is your answer. I've been using it to synchronize the data on 20 branch servers with the big corporate server for backup onto one big tape drive every night for the last two years. Email me if you need help setting it up. ports/net/unison Brian Doherty wrote:> Firstly let me say that I'm not sure if this is the right list to post to, > so if I am incorrect I apologise.
