rsync
rsync is the perfect tool when you need to synchronize two files or file trees, be it just your homedirectory or a whole server. It's basic operation is like scp or rcp, but it has many more options which aim to keep traffic low if the amount of identical files on sender and receiver is high.
cookbook
Synchronize a directory
rsync -av -e --delete ssh <directory to sync> <username>@<remote host>:<remote directory>
Migrating a server
To migrate a server,
rsync -avH -P --numeric-ids -x --delete / <additional mountpoints> <target>
usually does the trick. This should result in an exact copy of the source tree and gives you fancy progress bars while you wait for the rsync run to finish ;).
Minimum working config
log file = /var/log/rsyncd.log use chroot = yes [modulename] path = /path/to/module read only = yes list = yes transfer logging = yes
