The pairing that makes this worth it
One TrueNAS machine is storage. Two, in different jurisdictions, replicating to each other, is the architecture the resilience article argues for: off-site, versioned, on hardware you control, held by a different company in a different country.
ZFS replication is incremental and snapshot-based, so the second copy is append-only in the way that matters — something that destroys the source does not destroy the history on the target.
Chassis matter more than the software here
Storage is the one product where the hardware specification is the decision. Drive count, controller, whether you want spinning disks for capacity or NVMe for speed, and how much RAM ZFS gets. Custom builds exist for exactly this — a 4U chassis with thirty-six bays behind an HBA is a normal request rather than an exotic one.
If you would rather not run the appliance at all, object and block storage are sold directly, priced per terabyte with no per-gigabyte egress fee.
Questions people actually ask
Can I replicate between two of your regions?
Yes, and it is a sensible thing to do — two machines in two jurisdictions held by two separate companies. Every region is the same price, so the choice is legal rather than budgetary.
SCALE or CORE?
SCALE. It is the Linux-based line and the one under active development; CORE is the FreeBSD-based predecessor. If you want the FreeBSD side, run FreeBSD and build it yourself.
What it is genuinely good at
- ZFS with the difficult parts handled: scrubs, snapshots, replication schedules and alerting that you would otherwise assemble by hand.
- Replication to a second machine in a different jurisdiction, which is the off-site backup the journal keeps telling people to build.
- Shares that work with what you already use, and object storage without a hyperscaler in the path.
Choose a different one if
-
FreeBSD
You want ZFS but would rather build the system yourself and not run an appliance.
-
Debian
Storage is a component of something bigger rather than the purpose of the machine.
That list is here because a page that cannot name a situation where something else is the right answer is an advertisement. Every image on this estate is included in the price of the machine, so there is nothing to sell you here — only the one that fits.
