A cursory search didn't turn up anything so hopefully this isn't a dumb topic.
So, I'm repurposing an old server and hoping to put it into "production" in my home lab soon. And I wanna play around with dedupe because I'm a glutton for punishment.
I'm going to be running a bunch of Windows VMs and that seemed like a pretty good candidate for dedupe. I have 4x 2TB Intel NVME drives and a pair of 58GB Optane drives that I can use for the dedupe table. I'm thinking of striping the 2TB drives and mirroring the Optane drives. And FWIW, the server (Supermicro X9) will have 512GB of ECC RAM.
My main question (ignoring the obvious "how stupid is this idea?") is what are my backup options, specifically as it pertains to ZFS replication? If I attempt to replicate that drive to one of my current backup pools (no dedupe) on my backup server, will it occupy the same amount of storage (deduped data + dedupe table) will it reinflate to its un-deduped size, or is it even possible to replicate a deduped pool to a non-deduped pool? Do I need another pair of optane drives for the dedupe table on the backup server?
And FWIW, if I can ever get the blankity blank T10 Protection off of my blankity blank Toshiba SAS SSDs, I might try something similar on that pool too, if there happens to be any additional pitfalls there I might need to be aware of, feel free to point those out too.
Thanks.
