Glacier Archive Must Have Non-Zero Length

Hello
Whenever I copy files from AWS S3 to AWS Glacier a lot of the files fail to copy. The error it gives is always the same: ‘Glacier Archive Must Have Non-Zero Length’. Can anyone tell me what this is and if there’s a setting to stop this happening and copy all files successfully?
Thank you.

[reply=“DavidC;d1411”] Do you have any files with 0 byte size in the data set? Glacier archive doesn’t support such files.

Thanks Matt. I think we probably have. I will check the logs.
