Error when backing up to S3

Hello all,

I have about 30 accounts on my Virtualmin installation which are backing up to S3 every night for around 6 months.

The last couple of days I keep getting an error mail from Virtualmin about a failed backup, when I search for the error it is always 1 domain that is playing up. The log reads:

Uploading archive to Amazon's S3 service ..
.. upload failed! Missing new endpoint in redirect : 

… completed in 1 minutes, 41 seconds

It doesn’t happen every day but at a random rate really,

Uploading archive to Amazon's S3 service ..
.. upload failed! HTTP connection to for /x/26-11-2013/ failed : Failed to lookup IP address for

… completed in 6 minutes, 57 seconds

Is there a way to see a bit more logging, or is it possible to open an issue and maybe make it retry a few times before failing a backup?


Do you happen to see more errors in the Webmin error log, located in /var/webmin/miniserv.error?


No doesn’t look like it, there are no backup entries recorded in that log file.

I have the same problem. Sometimes it works, sometimes it does not. Weird…

I didn’t get the error since my last post, maybe something changed in 4.04 or it fixed itself :slight_smile: Anyway I would plead for a dedicated backup logfile
