Now Create a script file for automatic dpsace backup. 
sudo gedit dspace_backup/backup.sh
Copy below text into file and save it.
#!/bin/bash
PGPASSWORD="dspace" pg_dump -U dspace -h localhost -Fc dspace | gzip > dspace_backup/dspace-$(date +%Y-%m-%d-%H.%M.%S).sql.gz
now=$(date +"%d_%m_%Y")
zip -r  /home/server/dspace_backup/$now-assetstore.zip /dspace/assetstore
zip -r  /home/server/dspace_backup/$now-log.zip /dspace/log
(Change [username] & [password] as per your Dspace Database Credentials).

Make this file executable by following command:
