The problem with using rsync to back up a mounted boot partition is, it's
not instant.  So while rsync is backing up one part, some other part is
probably being changed.  So if you're lucky, you might end up with a
functional bootable backup, but you'll have some unknown bit(s) of
corruption that may or may not be fatal.

If you want to get a good bootable backup, you'd have to boot from something
else before backing up.  Then, if you want it to be bootable should you ever
have to restore and use it, fsarchiver would be a better bet than rsync.  An
image backup with dd would also work, but the boot partition would have to
be smaller or equal to the backup location.
