This is just a guess, but ... it sounds like you are trying to use the past state of web site as a backup mechanism for a website, and that really isn't going to work. The wayback machine stores a static copy of the HTML for a site as I explained to your last question:
Can the wayback machine cache audio files attached on posts?[
^] - it doesn't store every change to every site, it doesn't store dynamic data in the server, it just stores the occasional "snapshot" of a site page and moves on.
If you want backups, the use Dropbox, or Google Drive, or OneDrive, or ... there are loads of places you can do that, some of them free. Wayback machine is not a good solution to anything in particular, other than an impression of what a site looked like back then.
