Hi
One possibility is your backups are corrupted, either due to the lack of server ressources or the Certificate module broke something.
You can check the integrity of your backups in two ways: a) inspecting them as discussed in "Re: Backup of courses fail in courses with .zip files" https://moodle.org/mod/forum/discuss.php?d=209990 or b) uploading them to another Moodle 1.9.19 which is known to be working.
BTW, have you installed and tested the Certificate module in the new Moodle?
