Yes, it is possible, but not really documented, so you'll have to do quite 
a bit of figuring out yourself.

The issue is with renewal of the CA certificates, because I think Box 
Backup can only trust one at a time. It will trust all clients or servers 
whose certificates are signed with the client or server CA key.

Yes, this is the only file that you need to back up in order to recover 
your data. Certificates can be regenerated, but this key cannot.

Cheers, Chris.
