# run a shell script 1 minute after midnight to package all configuration files and database files into a tar ball file. Name the tar ball file as <date>-primary.tar for all the files for your primary DNS server, <date>-secondary.tar for your secondary DNS server, and <date>-master.tar for your master NIS server, and <date>-slave.tar for your slave NIS server. Pull the tar ball files to the corresponding directory on the backup server.
# Create a status file in the corresponding backup directory to indicate when the backup tar ball file was created and when it was successfully backup to the backup server..
