How can I use the “aws S3 sync” for syncing all the files and directories?

63    Asked by CarolynBuckland in AWS , Asked on Mar 6, 2024

I am currently managing a data backup solution for my particular company’s AWS S3 buckets. Recently, I have executed an automated backup process by using the AWS command line interface’s “AWS S3 sync” command. However, I have noticed that some files are not getting synced properly which is causing discrepancies in my particular backup. How can I troubleshoot and ensure that the “aws S3 sync” Command is reliable for syncing all files and directories?
