How can i set a cron job for this particular case

Question

"Whenever an admin user logs out his home directory,it should be backed up to /backup directory."

Answer 1

Not sure if you can use cron, but you can try to add backup commands to .bash_logout file which is located in admin's home.

To start backup in separate process try to use at.

at now <<EOF
# your commands to backup
