I use daily cron job to backup latest data to extranel USB ( connected
to different computer than backuppc and use NTFS as files system )

Here script what I use: ( hope it will help someone.

#!/bin/sh

LOG=/tmp/usb.log
# localdirectory
LDIR=/mnt/tmp
#host to backup
$BKHOST=server1
#remote host
RHOST=vhoc2h
#remote directory
RDIR=/mnt/usb
#remote usb device
RDEV1=/dev/sdg1
RDEV2=/dev/sdh1

mv $LOG.old $LOG.old2
mv $LOG $LOG.old

echo `date` > $LOG
echo 'staring backup to extarnal usb' >> $LOG

FILENAME=`date +%Y.%m.%d`
if ssh $RHOST "mount.ntfs-3g $RDEV1 $RDIR"
then
echo "mount USB ok" >> $LOG
    if sshfs vhoc2h:/$RDIR $LDIR
        then echo "mounted ok" >> $LOG
        else echo 'eror mounting sshfs' >> $LOG
        exit 1
        fi

# clean oldweeek: and dayfiles
#mkdir -p $LDIR/BACKUP
find $LDIR/BACKUP -mtime +3 -exec rm {} \; >> $LOG 2>&1
find $LDIR/BACKUP -type d -empty -exec rmdir {} \; >> $LOG 2>&1

/usr/share/backuppc/bin/BackupPC_tarCreate -t -h $BKHOST -n -1 -s \* .
| /bin/gzip > $LDIR/BACKUP/$FILENAME.tar.gz
sync
else
 echo 'error' >> $LOG
 exit 1;
fi

echo 'Backup finished' >> $LOG
df -hT >> $LOG

umount $LDIR >> $LOG 2>&1

#umount remote usb drive
ssh $RHOST "umount $RDIR" >> $LOG 2>&1
