Backing up data over LAN


I'm backing up some data over my LAN for a reformat, and I was wondering what the best way to do this would be. I'd like the transfer to be resumable and check for errors in transfer. I'm thinking about using rsync, but I'm not sure if it would be the best solution. Any ideas?

Also, I'm looking for a permanent, incremental backup solution. What would be the best way to do this?

I would say probably rsync for 1st qn and definitely rsync for 2nd qn. Of course, if you are talking about multiple systems, you may want to look at Amanda, rather than hand-rolling your own soln.

Welcome to LQ!

IMO rsync is the only app that meets your requirements. We incrementally backup all
the comps in this LAN to the server nightly with a cronjob, such as:
root@paul:~# crontab -l | grep silas
#This is to backup silas/mingdao every morning at 1:00 a.m.
00 1 * * * rsync -va --exclude='kernel' -e "ssh -o BatchMode=yes -o user=root -i /root/.ssh/identity.silas"    silas:~mingdao /backup2/silas/
That is passwordless login by root from the server backing up my workstation, silas.
You will notice I don't back up the OS, just the data; all of which is stored under ~/.

We probably need to know more about your network, number of systems and platforms, configuration, hardware available for backup, more specific backup requirements, etc. to give the best advice. rsync is certainly a good solution for some situations. Amanda is my choice for network backup of multiple servers. It will centrally balance the load on your network and systems by distributing the full and incremental backups over whatever backup cycle you define (e.g. over the week).

Thank you for all the replies.

This is my setup:
I have a laptop and a desktop. I primarily use the desktop right now. I'm switching the desktop from Kubuntu to Gentoo and RAIDing it, so I need to back everything up to the laptop. After I do that, I'll be using the desktop as a home server, and the laptop as my main machine. Depending on whether I can get some of the stuff I had problems with (like wireless) working in Gentoo, I may or may not use it on the laptop. If not, I'll be using Kubuntu on it. I'll be regularly making incremental backups of the laptop to the desktop.
