Use the disk archiver (DAR) to perform a full backup every other month, otherwise create an incremental backup.
#!/bin/bash
source /etc/default/backup
MONTH_TWO=$(date -d "- 2 month" '+%Y-%m')
MONTH_PREV=$(date -d "- 1 month" '+%Y-%m')
MONTH_NOW=$(date '+%Y-%m')
DATE=`date +%Y-%m-%d`
HOST=`hostname`
