Save logs in S3 bucket

Hello.

Yes, it is possible to export logs from CloudWatch Logs to S3.
If you want to do it manually, you can follow the steps in the document below.
https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/S3ExportTasksConsole.html

If you want to do it automatically, you can set up a subscription filter and KinesisDataFirehose in CloudWatch Logs.

Alternatively, you can automatically send logs to S3 by using the EventBridge Scheduler and executing the API "CreateExportTask".
