Any data that isn't securely backed up, including offsite, isn't really
important to you.  However, having other measures in place can be
worthwhile as well, for convenience if nothing else.  

In particular, a UPS is usually a good idea, and monitoring it so the
system does a clean shutdown before running out of power can make it
even more so (not in all situations, but in many).  Integrity checks on
files will catch damage to files; ZFS does this automatically, but
mtree(8) can do various types of checksums to serve the purpose as well.
