Yes, because you'll likely corrupt things unless you can do something to
prevent writing to the disk during that time. Unfortunately you'd only
notice that corruption upon a restore, when it's too late.

Could you create another instance, use clustering for your NSS resource,
and then backup one node at a time failing services back and forth? Since
you have NSS these are OES boxes and you can use Novell Cluster Services
(NCS) for most services (sans eDirectory) which would have a replica on
each server anyway.

Other options may be using some kind of filesystem snapshotting
technology. I am not sure what that'd look like from the host, or if your
host's filesystem has that as an option, but maybe it'd work. I prefer
the cluster option because it gives you another benefit (failover) at the
same time.
