The main benefit that users can expect to receive from the AWS sync command as opposed to the cp command, is that by default, the sync command will effectively sync or download multiple files between two specified directories. AWS notates that users only have the ability to download one object at a time, and not multiple at once. Check the list of CLI commands that can be used to accomplish downloading multiple assets.
Depending on the method of encryption for your amazon s3 objects, users have the ability to download and decrypt them. Furthermore, users that are attempting to download multiple objects that are encrypted, it is important that their accounts have the appropriate permissions necessary to decrypt the objects [5].
