Specifically, review the documentation for and use the "-P" option for
rsync, which can use rsync automatically. Rsync over ssh actually has a
number of concrete advantages over scp: In particular, using the "-a" or
related options, it can copy symlinks as symlinks, and using the "-H"
option, it can copy hard links as hardlinks. The syntax take a bit of
practice, especially to handle directories.
For example, to replicate /etc from one host to a backup on a localhost:
Note the options used, and the trailing slashes.
rsync -avH root [at] srchos:/etc/ /backupdir/etc/
