FAQ

Common questions

Why use on-premise NAS instead of AWS S3, Azure Blob, or Backblaze B2?

At scale, on-premise NAS is dramatically cheaper. A NAS24 at $8,995 with 24x12TB drives stores ~250TB usable for one-time cost. The same capacity in AWS S3 costs ~$5,750/MONTH at standard pricing. Payback is 1-2 months, then it runs for years. You also get full control: no egress fees, no rate limits, no vendor outage exposure.

What about backups and offsite redundancy?

Standard practice: deploy two eRacks NAS units (production + DR) at different sites, sync via ZFS send/receive nightly. We can pre-configure rsync, restic, or zrepl backup jobs at build time. Many customers also send a final copy to Backblaze B2 or AWS Glacier for archival.

Which storage OS should I choose?

TrueNAS Scale (FreeBSD-derived) is the SMB default - mature ZFS, pretty web UI, full NFS/SMB/iSCSI/S3. Proxmox if you want NAS + VMs in one box. Ubuntu 26.04 LTS for full control if your team is Linux-fluent. We pre-configure whichever you pick.

How do I migrate from existing NAS or cloud?

For NAS-to-NAS: ZFS send/receive over the network, or rsync over SSH. For cloud-to-NAS: rclone is the standard tool, supports S3/B2/Azure/GCS. We can pre-stage migration scripts at build time and walk your team through cutover.

What happens when drives fail?

ZFS RAIDZ2 (default) survives any 2 simultaneous drive failures. RAIDZ3 survives 3. All chassis are hot-swap - pull a failed drive, slide in a new one, ZFS rebuilds automatically. We ship spare drives on request.
