Using Wayback machine to import posts

Hi guys, I was not able to renew one of my domains because of health issues(codvid-19). So when I recovered from my illness, I found out that someone has already bought it. Please, does anyone know how I can retrieve some of the posts from the Wayback machine and import it into my new site?

If Wayback didn't archive your site: no.

You can't use Way Back Machine to export your posts. It's simply an archive, more like a snapshot, of your site that they have on file. You would need to MANUALLY copy the content over to your new site, assuming they have a snapshot of your posts/pages that you didn't have a backup of.

EDIT: Make this a learning experience to always keep a recent backup of your website's files and database.

If it's a Wordpress site, consider giving a tool called Wayback Machine Downloader (Search for it) a try. Not my product. Just something that came up when trying to find a solution for your problem, but as @osake said - you should always have backups no matter what. Makes life a hell of a lot easier.
