• Inside the file backup.sh put next code:

#!/bin/bash
/opt/jebackup/bin/jebackup.sh -s /home -d /mnt/NAS/backups -X "*.zip|*.rpm|*swp|*~|core" -f "%Y%m/%Y%m%d-%s"
/opt/jesteban/bin/jerotate.sh -d /mnt/NAS/backups  -m maximum_size -a remove -s ROTATE_MAXIMUM_SIZE_TARGET_MB=50000 -s NO_REMOVE_FILES_NEWER_THRESHOLD_SECONDS=3600 -s RECURSIVE_BACKUP_FILES=1

This configuration make:

• A full backup on the fist day of month, if you want a void this behaviour please change "%Y%m/%Y%m%d-%s"for "%Y%m%d-%s"
