i think i need to change only this

 

# Where to create the backups; It should already exist

BACKUP_DIR=/mnt/backups/fwatl01

# Filesystems to backup seperated by spaces and the entire string in double quotes; each must start with /

FILESYSTEMS="/root /etc /var/lib/rpm /home /var/named"

 

but i don't know what it the Variables for the user file !
