- From version 0.9.0, UpdraftPlus features a resumption feature - if you wait 5 minutes and visit a page on your site, then it should re-try not-yet-uploaded files. If that fails, then turn on debugging and paste the debug log (log in via FTP, and look in wp-content/updraft) into the support forum.
