# remove older backups
find ~/backups/* -mtime +30 -exec rm {} \;

BDIR=~/backups/
DATE=`date +%Y-%m-%d`

# only backup certain sites to save space
# leaving out test/play sites

for i in ${SITES[@]}; do
    tar -xcvf ${BDIR}${i}.${DATE}.tar.gz /html/${i}
done

# remove the old latest grouping
rm ${BDIR}latest.tar.gz

# now put all of the latest into one single tarball, so it can be moved to wherever
tar -zcvf ${BDIR}latest.tar.gz ${BDIR}*.${DATE}.tar.gz

# now copy to wherever, in our case we're copying to Dropbox
cp ${BDIR}latest.tar.gz ~/Dropbox/ThisIsOurBackupFolder/latest.tar.gz
