Oh sorry, didn't see your comment. get_footer() seems to be some a function to add padding to a tar block. Not sure how important it is, since we seem to be doing fine without it.
As for how common no-encryption is, I'm confident it's relatively common among Deja Dup users. Encryption is the default, but turning it off is a simple check when starting your backup for the first time. It seems sensible if you already trust the destination and are using https or ssh or some such.
I also found other corruption issues that are not specific to no-encryption mode, addressed in the linked branch above.
