Two encrypted, offline WD Elements drives that form the cold tier of the 3-2-1 backup strategy.
Two encrypted, offline WD Elements drives that form the cold tier of the 3-2-1 backup strategy.
Off-site Synology DS723+ NAS with RAID 1 and BTRFS snapshots, replicated continuously via Syncthing as the hot backup tier.
Shared cluster resource that declares the `StorageClass` definitions every PVC in the homelab targets — Longhorn-encrypted, Longhorn-replicated, and NFS-backed variants.
Continuous, peer-to-peer file synchronisation — the engine that keeps the off-site hot-storage tier (Maresa Synology) in step with the primary datasets.
How a byte written to a Longhorn PVC ends up in three places — warm (Restic to Hetzner S3), hot (Syncthing to the off-site Synology), cold (encrypted WD Elements drives) — and what it takes to restore from each.
2U rackmount TrueNAS SCALE NAS built on AM4 with the ASRock Rack X570D4U, LSI 9211-8i HBA, and Intel X520-DA2 10 GbE NIC.
