Backup your route53 records to s3 using the Boto3 library
This is a nobrainer backup for projects that you don't have in Terraform, or if you have a LOT of small records that don't really sit well in your Terraform but you don't want to clean it up.
Anyway, I'm not judging anyone, just throw those records in a bucket. :) If someone changes them then panics, we've got your back!
You can run it daily on ec2.
it would require using the /tmp folder but you could make it a daily aws lambda function too.
