I use zfs. This is how I archive:

cd /bread/qresearch/ && wget -nH -k -p -np -H -m -e robots=off -I stylesheets,static,js,file_store,file_dl,qresearch,res -U "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20070802 SeaMonkey/1.1.4" –random-wait –no-check-certificate http:// 8ch.net/qresearch ; snapshotname=$(date +%Y%m%d-%H%M) && zfs snapshot bread/qresearch@manual-grab-n-snap-$snapshotname

The four main parts are:

Change to directory

And if successful wget the board

Regardless of success set a snapshot time

And if success create a zfs snapshot
