Reartes Guillermo mentioned the same thing with RAID in BZ 951244, so I checked my system UEFI settings and indeed it was configured for RAID. I switched it to AHCI and that solved the problem! No more backup GPT corruption! I switched it back to RAID just to be sure and the backup GPT was corrupt again. I guess I'll leave it in AHCI since I wasn't using the hardware RAID anyway. Thank you!
