Hi Peter,
I don’t think there was any other backup plugins that were running at the same time — I tried running the scan a few times at different times throughout the day and it was taking a long time for all runs and if it was a plugin that was running at the same time, it’s a little odd if it happened during all the times I was running the scan? Though I inherited the site so I’m not really sure which plugins would cause this. I can investigate the plugins further but I also just sent the Diagnostics report, kindly check as well for me so that if there’s anything you notice, you can let me know.
Thank you.
