AWS Lambda Python Script to create Database Snapshots

Posted byRamasankarPosted inAWS, AWS Lambda, Python, RDS

The below script is used to create a database manual snapshots on all regions in an AWS account.  RDS support automatic snapshots which are very useful for point in time recovery but it does not protect you from accidental deletion of RDS instances.

Here are the reasons why we need manual snapshots

  1. Accidental RDS Instance Deletion
  2. Cross region backup
  3. Long term retention

import boto3
import time
import sys

def lambda_handler(event, context):
ec2Regions = boto3.client('ec2')
awsRegions = ec2Regions.describe_regions()['Regions']
for region in awsRegions:
rds = boto3.client('rds',region_name=region['RegionName'])
try:
current_date = time.strftime("%Y-%m-%d-%H-%M-%S")
print (current_date)
print (region)
response = rds.describe_db_instances()
try:
for rdsinstance in response['DBInstances']:
if (rdsinstance['DBInstanceStatus']=='available'): 
try:
shotIdentifier = rdsinstance['DBInstanceIdentifier'].replace('_','-') + current_date
rds.create_db_snapshot(DBInstanceIdentifier = rdsinstance['DBInstanceIdentifier'],DBSnapshotIdentifier = shotIdentifier)
except Exception as e:
print ('Error::%s'%e)
else:
print ('Instance NOT available Instance State is %s and Engine is %s'%(rdsinstance['DBInstanceStatus'],rdsinstance['Engine']))
except Exception as e:
print ('Error::%s'%e)
except Exception as e:
print (e)
#lambda_handler(None,None)

Hope you enjoyed the post.
