Are archive.org and the Wayback Machine the only free internet archive sites?

I'm looking for web pages of stuff I had posted from a site that was taken down. I can't find cache files of it-I managed to find some pages of it in the Wayback Machine but some pages it says "aren't in the archive". Are there any other free internet archive sites besides archive.org and the Wayback Machine, or are those the only two? Please let me know-thank you.
