Comment on S3 as a Git remote and LFS serverparentComments−laurencerowe1yUnfortunately this functionality is much more limited in S3 as you can only use `If-None-Match: *` to prevent overwrites. https://docs.aws.amazon.com/AmazonS3/latest/userguide/condit...GCS also allows for conditional overwrites using `If-Match: <etag>` which means you can do optimistic concurrency control. https://cloud.google.com/storage/docs/request-preconditions−ncruces1yYeah, it might still be possible to implement a mutex based on just the existence of an object, but it'll be harder to add expiration/liveness which I find essential.
