There’s now (since yesterday) a bit of why Karin Midular did not have a backup clone in the end of the lore article about her.
TL;DR: no one knows for sure because these are private matters we Minmatar do not discuss publicly, but probably she subscribed to a “one body, one mind” philosophy that precludes copies of minds or bodies (but her version would have allowed an emergency cloning, which sadly was not succesful).
See this thread for more discussion on the new info on Minmatar attitudes to cloning that bit reveals.
