Description of my issue: When using a cron job, on and about half the time the upload to Amazon s3. And sometimes the backup (Profile 1) runs as long as 3 hours when it doesn't fail. I have not included the entire cron job messages, just the errors. I figured with the log, you may not need the configs, but if you do, please let me know

There are two profiles (1 and 2) I set up Profile ID 2 trying to figure out why the other one was failing. After reading the troubleshooter I've gone through each profile to see if they differ hoping that would solve my problem. They "appear" to be the same. In both profiles, the split part size is 20.

When I backup from the backend, ID 2 works, and ID 1 failed until I switched the part to 20. That shouldn't make sense, because I believe I have them both set to 20. Maybe I need to go to 10, but didn't try that since it is intermittent.

Disabled multi-part uploads is off

Delete archive after upload is checked

Process each part is unchecked.

I'm not having any problems with other sites at cloudaccess

My next project is switching to UNiTE so I can use it to test backups.

Thanks

That makes perfect sense. This failure has to do with a timeout, as discussed in our documentation.

Sometimes it happens. It's not a bug in our software, it's not a problem with your host. It's an intermittent problem with Amazon S3. It looks like sometimes they get congested and start dropping connections. It happens to me for one every 10 backups (it used to be one every 50 last year). After the backup is complete I can go back to my site and retry the upload. If I insist several times it does manage to establish a connection and upload it. Sometimes the upload works on the first retry, sometimes it takes a dozen or so retries. Unfortunately there's nothing you or I can do about it :(

Thanks. The cron runs at 1:15 a.m. -- probably half the world is backing up in off hours. I'm betting changing the time may help. I missed the part about timeouts. I was focused on settings.

Please close the ticket. Thanks again!
