So you press Ctrl + S on every page and save it to a folder? How is that useful?
Maybe you want to use it for offline viewing for some reason? Or maybe you wanted to create a similar website. Don't think he uses Control + S though, since it is too much work. He probably uses HTTrack (free program) to do it. OP - Your title is misleading, based on the stuff you said. If I buy your service, I expect all the files, based on your title. Will I get the backend at all? Nope. Will I get the DB? Nope. The DB/backend is part of "all the files" though.
I use a $120 premium software for this, just cause it seems to work much smoother than HTTrack, has less bugs, and doesn't take like 2 weeks to clone one single website. Basically this service is just for you to save time and effort.
And yeah, you're right, I do not clone databases.
But if anyone is curious, I'm cloning bitcointalk right now, and it's going great so far! Looks identical. I will be making a free website to put the bitcointalk clone up as a demo.
And really, like said before, this service is for the lazy ones. Just like, technically, most other services.
