Is there anyway to map the files under indices directory to its corresponding snapshot? or any API which exposes the UUIDs/IDs used for these indices in the snapshot?

Technically the answer is yes, because Elasticsearch does exactly this mapping when restoring from a snapshot, but it varies from version to version and can't be relied upon.

The only reliable way to do this is to tar up the whole repository. You can create a separate repository for this operation if you do not want to transfer all the indices. You can also probably perform an incremental copy of an active repository using something like `rsync`, as long as you are careful not to attempt to access the destination repository while the copy is in progress.
