Re: Backup over the internet.
Hi Dan, What is the easy way to back up over the internet? What software should be used? You *could* use rsync. Performed over ssh, this enables you to backup quickly and safely, depending on what you'd like to backup. It's a killer tool, AFAIAC. http://rsync.samba.org/ and I guess `man rsync`. HTH...

I have been using afbackup (http://sourceforge.net/projects/afbackup/) with Linux for the past two years. I saw in the ports tree and I would go with it (haven't though tried the software that the others have recommended). ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Backup over the internet.
As I understand it dump will not backup everything reading the Freebsd book. I have a 1.5Mbps connection. Files seems to be about 3.1 Gigs each on 4 different machines . I have a freebsd box with extra 12 Gigs of space that I can save to. I would like to save to a cd writer on the same machine it is a Liton CDRW but that other task getting it running to copy. I think if I had a choice I would have my installation on a cd for the ports and freebsd I need. Then save the data only.

Re: Backup over the internet.
Something piped through ssh using DSA keys. e.g. on the machine which you want backed up (client) to the machine where the backup file lives, client machine: su root # if you have not yet created your ssh keys, do so now ssh-keygen -d on the server machine, pw useradd clientmachineid -m su clientmachineid cd ~clientmachineid ssh-keygen -d cd .ssh # from the client machine, put the root's id_dsa.pub and ONLY the .pub file here under the name authorized_keys2 #on the client machine, ssh [EMAIL PROTECTED] #if all goes well, you will login without a password. Now the backups. If you need to preserve file access times and want to do incremental backups, use dump. If you dont care about munging file access times, and its just simple files, tar will work. /sbin/dump -0uan -f - / | gzip -9 | /usr/bin/ssh -2 -c blowfish [EMAIL PROTECTED] dd of=/pathtohomedirectory/clientmachineid/dump-root-l0.gz /usr/bin/tar -cpzf - /usr/local/etc /etc/mail/ | ssh -c blowfish [EMAIL PROTECTED] cat - /pathtohomedirectory/clientmachineid/backup.`date +%d`.tgz Blowfish is a bit faster than the others so I specify it. ---Mike At 09:08 AM 7/15/2003 +, DanB wrote: What is the easy way to back up over the internet?

Re: Backup over the internet.
I've been using a program called rdiff-backup ( http://rdiff-backup.stanford.edu/ ), based on librsync. This package creates a mirror of your server (or any portion thereof) on a remote server, and keeps track of changes. It only sends changes (ie diff) across the wire, including binaries, so after the initial copy it's pretty bandwidth efficient. It's not in ports ( or wasn't recently ) and takes a little extra work to build it, but IMHO it's well worth the effort.
