Reverse engineer a snapshot creation process on AWS / EC2

I am faced with the following situation:

There is an EC2 instance on say eu-west-1.

When selecting Snapshots on the EC2 service, I see that periodically, every 7 days on the exact same time, a snapshot is taken from the particular image.

The problem is I cannot find:

Via what other (managed) means could such a process be carried out periodically with such an accuracy on time?

edit: The corresponding CloudTrail log entry is:

(actual values regarding user, event and request id have been scrambled of course)

AWS access key:
AWS region: eu-west-1
Error code:
Event ID: 454g0236-x4e6-43c1-3565-4xb6d541c2h1
Event name: CreateSnapshot
Event source: ec2.amazonaws.com
Event time: 2019-11-23, 05:00:44 AM
Read only: false

If i understood you question you are looking for a way to know if Lifecycle Manager is available for EC2 snapshots.

Below given links should be able to help you on the same. For enabling a custom Snapshot Lifecycle policy manually refer Snapshot Lifecycle

For automating a solution for the same please referautomation of snapshot lifecycle

There are multiple other options,

  1. Check Cloudwatch events, if there is any event triggering. Most probably this one is in your case.
  2. Cronjob on an EC2 instance.
