I have four virtual virtual servers which I backup daily to an Amazon S3 bucket for a few years now (one file per server). About a week ago the backup started to fail for one of the virtual servers. The error message I get:
Error message: Uploading archive to Amazon's S3 service .. upload failed! Empty response to HTTP request. Headers were : (I can't find anything else in any of the other log files.)
The file is about 200MB and the backup process gets cancelled after approx. 40 minutes.
The other virtual servers of the backup are backed up just fine. I made a manual backup out of the scheduled backup (download in browser) and that went just fine.
Can anyone help me out?
Thanks and regards
