Restoring a wiki article from backup

So, one of the users deleted a wiki page by mistake (including childs etc.). Now the user asks if we can restore the wiki pages.

Based on my searches, I know there is no easy solution/way of doing this for the time being - we do however have daily backup.

Did anyone take the time to write an how-to recover/restore single items like wiki pages, issues etc.? I am aware it will require some sql-fu etc.
