Something like this should work... BASE=/backup/psql # edit for your situation REMOTESOURCE=dbhost::psqldumps/ # again, edit TODAY=`date +%d-%m-%y` # I prefer %Y-%m-%d, sorts better cd $BASE YESTERDAYS_BACKUP=`ls -td ??-??-?? | head -n 1` rsync -a --compare-dest=../$YESTERDAYS_BACKUP $REMOTESOURCE $TODAY/ Paul Slootman -- Please use reply-all for most replies to avoid omitting the mailing list.
