Source gap audit — backup/DR vs sub-GHz Wi‑Fi (homelab + farm)¶
Purpose¶
Short evidence map for what the vault had vs needed to answer decision-safe questions on (1) farmOS/homelab backup strategy and (2) sub-GHz Wi‑Fi (802.11ah / HaLow) for farm sensors—without fabricating operator procedures.
1. Backup strategy comparison pages¶
| Category | Previously in vault | Gap | Addressed in this wave |
|---|---|---|---|
| Logical DB backup into object-style repos | Generic PostgreSQL primers; no restic operator capture | Official restic patterns for --stdin-from-command (e.g. DB dumps) and snapshot hygiene |
restic captures, restic removing snapshots + source note |
| Kubernetes / CSI volume backup | Homelab narratives; no Longhorn operator capture | Longhorn system backup / restore bundle semantics | longhorn captures etc. + same source note |
| farmOS + containers | farmOS model docs; overview | Docker development/hosting capture for compose + DB sidecar pattern (epistemic: v1/MariaDB era in capture) | farmOS Docker capture |
| farmOS 2.x PostgreSQL specifics | Hosting links in overview, not full backup runbook | Still partial—confirm current farmOS.org/hosting for DB engine and backup expectations; wiki synthesis cites patterns, not a single blessed command | Called out in backup strategy comparison |
Remaining gaps (explicit)
- Official farmOS backup/restore chapter as a dedicated processed capture (optional future ingest).
- PostgreSQL vendor backup docs (e.g. continuous archiving) if the deployment moves beyond single-instance compose.
- Immutable air-gapped tape/object-lock patterns for compliance—out of scope unless sources added.
2. Sub-GHz Wi‑Fi / HaLow how-to pages¶
| Category | Previously in vault | Gap | Addressed |
|---|---|---|---|
| 802.11ah / HaLow concept | Wi‑Fi HaLow concept, multiple article captures |
Consolidated how-to narrative | Sub-GHz Wi‑Fi farm sensors — deployment guide |
| Deployment / bridge patterns | Silex-style PoC capture | Step-level outline + constraints | Cites how-to 10x reach HaLow |
| vs LoRa / Meshtastic | Meshtastic vs HaLow vs Wi‑Fi, LoRaWAN vs Meshtastic |
Four-way field-network table including LoRaWAN | Wi‑Fi HaLow vs LoRaWAN vs Meshtastic vs conventional Wi‑Fi |
| IEEE / chipset datasheets | Morse Micro etc. in off-grid index | No new PDFs in this inbox wave; still rely on existing cluster | Off-grid power/RF source index |
Remaining gaps
- Regulatory domain / channel plan per country—must be verified for your jurisdiction at deploy time.
- Vendor-specific OpenWrt/build guides as processed captures if a chosen CPE is fixed.
