Upload Locking Up

Hi,

Does the backup resume at all after a while?
If not, could you check your PHP error logs (or ask your hosts to check)?

Best Wishes,

It doesn’t seem to be the scheduler since I do get email reports of the backups eventually working, but running them manually makes it incredibly obvious that it is running into issues.

I’m running a self hosted WordPress install on my VPS, anything I can do to look into this more? DNutbourne mentioned PHP error logs, would I need to view those over SSH or can I view them in Plesk?

If PHP error logs are enabled, you should be able to access them through Plesk.

If you are getting reports that the backups are eventually working, what is the approximate time-frame? Could you send the log file of a backup that did eventually succeed?

I found a few related entries in the error log: https://pastebin.com/qF1GwKTe

Please can you send a log file from a backup that eventually worked? When you say “eventually”, you’re saying there’s a delay? The more information the better! It’s sounding like an infrequently active WP scheduler, based on the sketchy information I can see. Is it an infrequently visited site, or one that’s not visited overnight, or something like that?

This is an often visited website, and the lockups tend to happen more often when launched manually, where as automatic backups rarely timeout (it does still happen from time to time though)

Here is the log from the last time it locked up. https://pastebin.com/cNF05ubb

Hi,

From the log, it appears that your FTP server is configured to deny Appending/Restart on uploads. This means that when a backup file upload is interrupted, it cannot be restarted.

You should be able to easily change this in your FTP server configuration

Thank you, it looks like that fixed the issue of not resuming, but I would like to figure out what is causing it to get stuck at that part and have to resume.

It shouldn’t be the file size, as I tried splitting the file size and it still had the same issue. At least it works every time now.

Hi,

There’s no “getting stuck”. What happens is that webservers are often configured to kill off tasks that run for more than an administrator-configured amount of time. (Administrator do this to conserve resources). Backups are usually the biggest task that you can do (since they want to read/write/upload an entire copy of the complete website), so they can hit this limit. UD copes with that by storing backup state and restarting from where it left off. That’s normal operation and nothing to be concerned about.
