Python script to take Amazon volume backup of an instance

Assumption:

1. AWS access key has a privilege to create snapshot.
2. Aws Tag name has to be passed as an argument.
3. Replace aws access key and secret key with proper keys

import boto,boto.ec2,boto.utils
conn=boto.ec2.connect_to_region('ap-southeast-1', aws_access_key_id='XXXXXXXXXXXX',aws_secret_access_key='XXXXXXXXXXXXXX');

reservations=conn.get_all_instances()
all_volumes_info = conn.get_all_volumes()


command_line_instance=sys.argv[1];
for name in reservations:
	for instance in name.instances:
		aws_inst_name=instance.tags.get("Name")
		#print aws_inst_name
		if(aws_inst_name == command_line_instance):
			print "perfect" + command_line_instance;
			for volumes in all_volumes_info:
				if volumes.attach_data.instance_id == instance.id:
					print "Taking backup of volumes";
					snapshot=conn.create_snapshot(volumes.id,command_line_instance);
					
					print "Instance ID:%s" %(instance.id);
					print "Volume ID:%s" %(volumes.id);
					print "Instance Name:%s" %(aws_inst_name);
					print "Snapshot ID:%s" %(snapshot.id);

Usage
python aws_create_snapshot.py AWS_INSTANCE_NAME

Future post with retention period and may be with configuration 🙂
