I experience similar on my nightly backups - tar exits with status '2' but
for the life of me I cannot work out WHAT exit 2 means. It still works fine,
but the non-zero return it just annoying.

If you're just compressing (ie, not creating a tar-type archive, just either
GZip (gzip) or BZip2 (bzip2) the WAL files.

BZip2 has incredible compression, but at the expense of speed of course.

sometimes tar  (gnu tar) exited with nonzero status for no reason on my 
system... no error msg or anything. I recommend something called star.
