Thanks for submitting this request. S3TransferManager in V2 does support Pause/Resume on Upload/Download in case of network loss - https://github.com/aws/aws-sdk-java-v2/issues/3120, but don't think it considers power loss events.
We'll review it with the Java SDK team further.
Regards, Chaitanya
Describe the feature
Update S3TransferManager to provide a mechanism to resume download / upload in the event of host machine power loss.
Use Case
My IoT application utilizes the S3TransferManager to download and upload files from Amazon S3. Ensuring the ability to resume interrupted download and upload sessions is a critical requirement to avoid unnecessary data transfer costs, not only during intermittent network disconnections, but also in the event of power loss on the device.
Requesting S3TransferManager to provide a mechanism to resume downloads and uploads from the last byte location after the host device has recovered from abrupt power loss.
