Xen users - Jun 2010 - partimage-ng command line backup of LV snapshot

Perhaps slightly OT, but I am trying to speed up a backup script which
takes an lv snapshot and does this:

dd if=lv_snapshot | gzip -c > /destination/lv_file_name.gz

Does anyone have an equivalent example using partimage-ng that they would
be kind enough to share? - I have been told it would be much faster/more
efficient, hence the question. Ten minutes of browsing the partimage-ng
docs have left me none the wiser...



Many thanks,

Matt
