You need to use <code>describe_snapshots</code> and properly pass in filters.

Also, the results are going to be a dictionary, not references to the Snapshot class so you need to update the way you pull out the attributes and delete the snapshot.

Something like:

<pre class="lang-py prettyprint-override"><code>from datetime import datetime, timedelta, timezone

import boto3
client = boto3.client('ec2')
snapshots = client.describe_snapshots(Filters=[
 {
 'Name': 'description',
 'Values': [
 'Created by CreateImage',
 ]
 },
 ])['Snapshots']

def lambda_handler(event, context):
 for snapshot in snapshots:
 start_time = snapshot['StartTime']
 delete_time = datetime.now(tz=timezone.utc) - timedelta(days=790)
 if delete_time &gt; start_time:
 client.delete_snapshot(SnapshotId=snapshot['SnapshotId'])
 print('Snapshot with Id = {} is deleted '.format(snapshot['SnapshotId']))

</code></pre>

Here's a version that works.

Note the use of <code>OwnerIds=['self']</code> which limits results to only snapshots created by your AWS account. Without this, it will return all publicly-available snapshots created by any AWS account.

<pre><code>from datetime import datetime, timedelta, timezone

import boto3

def lambda_handler(event, context):

 delete_time = datetime.now(tz=timezone.utc) - timedelta(days=790)

 ec2_resource = boto3.resource('ec2', region_name='ap-southeast-2')
 snapshots = ec2_resource.snapshots.filter(OwnerIds=['self'])

 for snapshot in snapshots:
 if not snapshot.description.startswith('Created by CreateImage') and delete_time &gt; snapshot.start_time:
 snapshot.delete()
 print('Snapshot with Id = {} is deleted '.format(snapshot.snapshot_id))
</code></pre>

I'm trying to delete old AWS snapshots but I need to exclude any with a description value that starts with "Created by CreateImage".

I've tried variations of boto3.resource and boto3.client. 

<pre><code>from datetime import datetime, timedelta, timezone

import boto3
client = boto3.client('ec2')
snapshots = client.snapshots.filter(Description!='Created by CreateImage')

def lambda_handler(event, context):
 for snapshot in snapshots:
 start_time = snapshot.start_time
 delete_time = datetime.now(tz=timezone.utc) - timedelta(days=790)
 if delete_time &gt; start_time:
 snapshot.delete()
 print('Snapshot with Id = {} is deleted '.format(snapshot.snapshot_id))
</code></pre>

Right now I have about 10 snapshots older than 790 days, 5 with a description that starts with "Created by CreateImage" and 5 that don't. In testing this out I want to delete those snapshots without that description.

the error I get is:

module initialization error: 'EC2' object has no attribute 'snapshots'

Delete snapshots except those with specific description
