Bash Script To Determine Retired Clients.

While in VDP you have a built in feature for unprotected VMs (That is VMs not added to VDP backup job) you might need a script to determine if VMs are missing from a backup job.

The script has a simple algorithm:
> The first time it runs it creates a file to gather all the protected client list
> The next time it runs it will check what is missing since the last protect client list.
> New added VMs will not be considered as Missing, however on Next iteration of script execution it will run a check to see if the new clients are missing.
> If you remove the first generated file for protected list post your second execution, then the third iteration will be void as it will generate a new protected client list.

The script has an email feature to send the output to a mailing address. If you want to exclude this, then discard line-21 to line-32. If you want to run the script as a cronjob, you can add it to crontab -e, but you cannot have manual email address input running in the script. You will have to create a constant for your email address and call it in the EOF.

The script can be accessed from my repository here:

The code {}

#!/bin/bash
	IFS=$(echo -en "\n\b")
	FILE=/tmp/protected_client.txt
	if [ !-f$FILE ]
	then
	client_list=$(mccli client show --recursive=true | grep -i /$(cat /usr/local/vdr/etc/vcenterinfo.cfg | grep vcenter-hostname | cut -d '=' -f 2)/VirtualMachines | awk -F/ '{print $(NF-2)}')
	echo"$client_list"&> /tmp/protected_client.txt
	sort /tmp/protected_client.txt -o /tmp/protected_client.txt
	else
	new_list=$(mccli client show --recursive=true | grep -i /$(cat /usr/local/vdr/etc/vcenterinfo.cfg | grep vcenter-hostname | cut -d '=' -f 2)/VirtualMachines | awk -F/ '{print $(NF-2)}')
	echo"$new_list"&> /tmp/new_list.txt
	sort /tmp/new_list.txt -o /tmp/new_list.txt
	missing=$(comm -3 /tmp/protected_client.txt /tmp/new_list.txt | sed 's/^ *//g')
	if [ -z"$missing" ]
	then
	printf"\nNo Client's missing\n"
	else
	printf"\nMissing Client is:\n"| tee -a /tmp/email_list.txt
	printf"$missing\n\n"| tee -a /tmp/email_list.txt
	printf"Emailing the list\n"
	FILE=/tmp/email_list.txt
	read -p "Enter Your Email: " TO
	FROM=admin@$(hostname)
	(cat - $FILE)<< EOF | /usr/sbin/sendmail -f $FROM -t $TO
	Subject: Missing VMs from Jobs
	To: $TO
	EOF
	sleep 2s
	printf"\nEmail Sent. Exiting Script\n\n"
	fi
	rm /tmp/new_list.txt
	rm -f /tmp/email_list.txt
	fi
