### Remember start time
CURRENTDATETIME=$(date +%Y-%m-%-d-%H:%M:%S);

### Sync data
s3cmd sync --no-progress --recursive --skip-existing --no-check-md5  $LOCALDIR $S3BUCKET;

### Mailing
if [ "${MAILLOG}" = "yes" ]; then
        TMPFILE=/tmp/s3backupsynclog.txt;
        echo "STARTED: ${CURRENTDATETIME}" > $TMPFILE;
        echo "ENDED  : $(date +%Y-%m-%-d-%H:%M:%S)" >> $TMPFILE;
        echo '' >> $TMPFILE;
        s3cmd du -H $S3BUCKET >> $TMPFILE;
        echo '' >> $TMPFILE;
        mutt $MAILRECEIPIENT -s "${MAILSUBJECT}. - ${CURRENTDATETIME}" < $TMPFILE;
    rm $TMPFILE;
