I think this is outdated, GNU tar seems to be able to preserve SELinux
contexts with GNU tar as well in the meanwhile (--selinux option, see
info pages, it's not mentioned in the man page).

I think running in permissive and fixing the issues that appear in
audit.log is the way to go (by either labeling the FS correctly, or by
changing the policy). I'm a bit puzzled because you get different
SELinux messages than me. I opened a BZ for fowner capability of tar:
https://bugzilla.redhat.com/show_bug.cgi?id=1280526 (that was on F22, I
updated to F23 in the meanwhile).

My current workaround is to setenforce permissive at the beginning of my
backup script and reset it to enforcing at the end.

FWIW, there is also a bug with the F23-shipped amanda (or with perl,
someone with deeper perl knowledge than me needs to judge that):
