Snapshots will do what you want. Whether Btsfs is suitably stable to
trust your data to is a different question. The last time I used it was
a couple of years or more ago, and my conclusion was that it was too
rough and ready for me to risk production data on. I haven't looked at
it more recently - it seems to be heading in the right direction though.
A filesystem is one of those pieces of code that really needs to work,
and be bulletproof. IMHO, that only comes from years of real world use
and bugfixing. Personally, today, I'd use ZFS instead - that has almost
decade of more of real deployment, and is battle tested. With a 16Tb
array, features liek the checksumming and protection from silent
corruption become really valuable. The ZFS on Linux project is
apparently pretty solid, or you could use FreeBSD.
