In this case, I would peek into something as below:
- a 3-way mirror or appropriate raidz2/3 for medium term, hot storage 
(5-10 years);
- send/recv the pool regularly on another server, possibly a remote one;
- LTO tapes with a good rotation policy for cold storage.

The real challenge, however, would be to keep the place safe from fire, 
theft, etc for so much time. So, you should really investigate a remote 
backup option. Cloud services could be tempting, but we have no 
assurance they will be online/available 40 years from now (ie: Amazon 
Glacier becoming a discontinued product, who know!).

I am not sure how Gluster fit the bill. Maybe via geo-replication? But 
using ZFS you have send/recv...
