Hi @ams1br
It’s most likely caused by web server timeout, increasing Query Output value should make the process quick enough to pass it before web server cancel backup process, please also disable PHP CLI and change backup method.
Follow these steps:
1. Go to “Other options” section
2. Change backup method: https://prnt.sc/1s1ofpa
3. Disable PHP CLI checking: https://prnt.sc/1sljr31
4. Modify query output: https://prnt.sc/1trxucl (set this value to 1000)
5. Save “Other options” section
6. Force stop both processes: https://prnt.sc/1trv1tm
Once done, try to run backup process again.
Let me know if that resolves your issue ??
Thank you!
