Corrupted zip on Amazon S3

Hello! I’m new here. First to say – thank you for great backup plugin! You doing awersome job. Sorry for bother but I need a little help.

So. All work fine. Local copy of backups working great. But when it uploads to Amazon S3 server its corrupted and I dont know why. Corrupted only one file by now – plugins.zip.

In logs all seems fine. When creating zip file:
