Error backuping a big tar.gz to s3

[niekappartmedia]

Hi all,

We have currently a problem with PHPBU not able to backup a tar.gz with a size of 11gb (fullbackup) to the s3 bucket. We get following message:

Exception 'phpbu\App\Backup\Sync\Exception' with message 'The promise was rejected with reason: Invoking the wait callback did not resolve the promise' in phar:///usr/local/bin/phpbu/Backup/Sync/AmazonS3v3.php:72

Any idea how to fix this.
