Wrong part number when uploading backup

[jimmypoulsen]

Hi

We have a fairly large Postgres database (345 GB). We've been using the backup feature and it's been working flawlessly up until now. Lately we're seeing the following error:

upload failed: - to s3://backups-bucket/postgres-my-database-2025-04-01-21-29-18.tgz An error occurred (InvalidArgument) when calling the UploadPart operation: Part number must be an integer between 1 and 10000, inclusive
Backup of backup/ has failed. Please investigate the issue.

I wonder if there's a limit to how large a backup Dokku Postgres is able to handle?

Also, I wasn't sure where to create this issue. Let me know if I should create it in https://github.com/dokku/docker-s3backup instead.

This sounds like a usage issue with the aws-cli - which is what we use under the hood - and actually something to fix with the setup in docker-s3backup, not here (though the fix will be inherited here of course). I don't have a database that large to backup, so I'll be depending on you or others to debug this and figure out the solution.
