Hello Everyone,
At work we have an Executone voicemail system that is alittle old perhaps, 486 but will run on a 286 if need be. It runs on a proprietary system. All the cards, video, dialogic, and the mainboard itself are
ISA which mount on the backbone itself.

Is there anyway to backup this system while running? Does anyone make and or support a raid card that is ISA?

Reason I ask is because the system died last
Thursday and it made for two very long days to get it back up.
Thank you in advance
