Lost private tabs

I had over 100 private safari tabs on my iPhone and I accidentally closed them all at once so that they are all lost. And there is no way for me to get them back since they don’t save in history. But after that I turned off iPhone backup meaning that the last backup made on my iPhone contained all of those private tabs.

will those private tabs be restored and come back to my phone if I install that latest backup? Or is there another way for me to bring back those tabs?
