Not really. FAT32 is very simple and normally has a copy of each FAT table stored as well. When something goes wrong with the first FAT table, there's a reasonable chance you can still use the 2nd copy. [1]

ExFAT is much more complex and AFAICT it does not have a 2nd copy of all of its data. [2]

Anecdotal evidence is that I personally lost data on ExFAT file systems, but also have had many customers with problems when they figured to use ExFAT for my backup products. If I see ExFAT in a support bundle than -by default- my suggestion for fixing issues is to reformat to a different file system. More often than not, that's the end of the open support case.

I had an external harddrive with exfat that lost all its partition information.

Worked one day, then few days later plugged it in and it was all gone.

Just write all your data twice, lol.

If one of them becomes corrupt in a non-obvious way, how do you know which it is? You need three copies to be sure.

Or you could save a hash as well

What if a bit flips in your hash file and changes that? Now you need to store your hash a bunch of times too!

I kid, this is what I do. I've recently been backing up my family photos/videos to various media and I've been hashing each file and storing a hash file alongside the media to compare to in the future.

no, not journaled
