When I use xz for archival purposes I always use par2[1] to provide redundancy and recoverability in case of errors.
When I burn data (including xz archives) on to DVD for archival storage, I use dvdisaster[2] for the same purpose.
I've tested both by damaging archives and scratching DVDs, and these tools work great for recovery. The amount of redundancy (with a tradeoff
for space) is also tuneable for both.
