Disaster/recovery Plan for BPCS

Hi, I'm new both to BPCS and to this List.
I'm also new to the IS Dept in a Factory where they just installed and
started BPCS in production...
Now I've got to prepare for a D/R Plan just in case...

Reading thru the archives I found several threads, but rather general.
Just one of them had something like
"I believe that journaling BPCS is essential to any BPCS energency
recovery procedure.Although BPCS does not include commitment control,
journaling may be
invaluable in both in case of a disaster, such as a disk crash, and in
debugging and investigating the BPCS database. "

To my surprise, I found out BPCS does not (am I wrong ?) any journalling
(at least in our shop).
I don't want to re-invent the wheel, so I'd like to know what you people
do as "normal" D/R procedures for your BPCS stuff. Just journal all
files as anything else?
Any other procedures?

Any ideas are welcome. TIA
