Hi @dotsey ,

Basing on your debug code, backup process seem to be successful.
I didn’t notice any errors in your logs, so I assume it’s a false positive.

Such false positive may happen when your browser loses connection with your server.

To confirm that, simply check if any new file is listed inside backup(s) list in our plugin settings.
That list can display only valid and restorable backups, if it’s there you don’t have to worry about anything, the backup was successful.

If the file is not listed or you want to resolve issue with false positive:

1. Go to “Other options” section
2. Change backup method: https://prnt.sc/1s1ofpa
3. Disable PHP CLI checking: https://prnt.sc/1sljr31
4. Save “Other options” section

Once done, try it out by running new backup.

Let me know if that resolves your issue 🙂
Thank you!
