I’ve had some difficulties getting the BackWPup plugin to work, it seems that you can’t backup everything in one job as the script takes too long to run and the server will terminate it, causing a failed job.
The 2 errors I was seeing are
- WARNING: Job restart due to inactivity for more than 5 minutes.
- ERROR: Uploaded file size and local file size don’t match.
Which led me to this post, which recommends a better way to structure your backup jobs, basically just split them out into content, plugins, install etc so they finish within the timeout threshold.
