I haven't read the thread in the kernel mailing list, so please
excuse me if I'm missing the point.
Xfsdump will read from the filesystem like tar (but more efficiently) and
does not need to read directly from the device, so it should be as
reliable as tar.
It is best, however, to run xfsdump on a filesystem when it is not being
used to reduce the chances of files and data changing while xfsdump is
running. This would also be applicable to tar, of course.
