but there is one small problem, which isn't so much the software, but it affects the software
Having a large website, it cannot back it up completely, it runs out of memory to complete the task (my website is nearly 7gb, so I would expect this to happen), so if you have a large website, seriously look at external back-up solutions
I emailed the developer who spent some time over the weekend and emailed my an updated version!
This also didn't work for me, but gave a good error message back as to why, my server was not configured with the right setting, unfortunately for me, I am on shared hosting and could not change the setting.
Again, the developer went off and did another update and now it works perfectly on my site.
Thank you for you hard work in sorting the issues I have had and I am glad I have been able to help you as well
