Every backup takes 8 hours to complete

Hello. I use your plugin on several different sites. It is very easy to use and typically has no issues. But on one of my sites I am experiencing an issue. Whenever I carry out a backup, it takes ~8 hours to complete. During that time, my site goes down several times with an HTTP Error 500 message. Can you help me troubleshoot this?

Here is some more info:

• I am using the latest version of the plugin (v1.16.0), and the latest version of WordPress (5.02).
• The total size of the ZIP files in the backup is ~500 MB. This is a bit large, but shouldn’t be causing the issue I’m seeing.
• In the UpDraftPlus log file are several timeouts/jumps in time stamp. But the log doesn’t seem to indicate the cause of those timeouts. There is one error entry that appears several times: “16105.342 (5) Binary zip: error (code: 9 – look it up in the Diagnostics section of the zip manual at https://infozip.sourceforge.net/FAQ.html#error-codes for interpretation… and also check that your hosting account quota is not full).” I can send you the full UpDraftPlus log file for your review. But can you confirm that it does not contain sensitive information? If it does not contain sensitive info, I can post a link here. If not, I’ll need a secure place to send it.
• I have PHP logging enabled, but there are no entries written to the PHP log during this time.
• As soon as I begin the backup, a few of my server stats jump from zero to max levels (screenshot). Specifically, “Physical Memory Usage” jumps from 0 to its max of 256 MB, and “I/O Usage” jumps from 0 to its max of 1 MB/s. They remain at max levels for essentially the entire 7 hour backup (screenshot).
• I also experience a timeout whenever I try to update the plugin. To be clear, an error occurs (screenshot; full error message here). But when I refresh the Plugins page, the plugin appears to have updated. Not sure if that’s related.
• I should also say that I can also replicate this timeout/HTTP Error 500 issue with other tasks. Notably, if I initiate a security scan using the Wordfence plugin, a very similar issue occurs (although it doesn’t last for 8 hours–it times out and fails rather quickly). And when I run a SiteCheck on my site from the Sucurit website, it also times out. Could be related to the backup issue, and all caused by my limited server resources, or not. But just throwing this out there for the best analysis of the situation.

Thanks.
