This 100% - it’s funny how it’s actually more reliable in my experience to use the encrypted sparse bundle. I can sling it over to my NAS no problem. I’ve restored from one and everything was perfectly fine. YMMV of course

That was my experience at first, but then it gets corrupted somehow and you have to delete it and start over. Happened to me multiple times with RAID 1, so pretty sure it's a software error -- I eventually just gave up.

Same here, lost my backup 3 times across some 6 years. Gave up and moved on to Kopia.

Have you run memtest on the machine in question? That kind of problem sounds like a classic bad RAM symptom.
