Aside from the suggestions already mentioned, also look at using rdist over a ssh tunnel.  See the man page for rdist.  This would be more efficient than nfs.

RDIFF-BACKUP ______________ Excerpts from the manual mention :- "The target directory ends up a copy (mirror) of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves symlinks, special files, hardlinks, permissions, uid/gid ownership, and modification times. ~ you can use ssh and rdiff-backup to securely back a hard drive up to a remote location, and only the differences will be trans­ mitted. Using the default settings, rdiff-backup requires that the remote system accept ssh connections, ~ " Version 0.12.6 November 2003 RDIFF-BACKUP(1) Man author: Ben Escoto _________________ best rgds __________

Why not using rsync with hardlinking? Only costs an inode for like files, takes care of files that have been removed (I don't see rdiff doing that), and is very well understood - you get a 100% "copy" of the directories at very low cost. Over a wireless link I can backup 3-4 gig in 2-3 minutes because 98% of the files don't change from day to day.

I would also recomend this - we use rsync for remote backups of 3 servers. In all, about 250G, and it takes about 10-15mins (Like Jon said, it only sends what is changed)

The link doesn't mention anything about doing this across the internet just another tool to use. As far as doing this across the internet unless you do not care who can see/intercept this data I would use either a VPN tunnel or ssh at the least (scp -r or rsync -e ssh). -- Ken Schneider UNIX since 1989 SuSE since 1998 * Only reply to the list please*

From the same page, bullet 4: <cite> Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted ssh connection. </cite> And in the FAQ there are a lot of things about ssh tunneling as well.
