Werner,

I'm not handling EMC2 storage, but I guess that you can do it easily.
Just be sure you are splitting the FSs after having stopped the
omservices, or if your prefer, use timefinder to make a third copy of the
omstore.

For your information, when omservices are stopped, nobody is accessing
anything under /var/opt/openmail/... , sendmail may still work but on
/var/spool/...
In my OM early times I used to backup the omstore using OmniBack-II and
backing-up the raw devices ... the Disaster Recory tests were always
successfully

Ciao Mauro
