Well, a few things going on:
1 – The file(s) is too large to upload via the web browser so it times out.
2 – uploaded the backups via FTP and tried to get that working, but didn’t work.
I can’t see any logs in that directory and cannot reproduce the error right now. I am trying again and just leaving the web browser open, maybe overnight, to see if it completes the upload. Progress bar not moving at all.
