# Operations / decisions
|
|
|
|
## Owner decisions
|
|
|
|
| Decision | Reason / accepted tradeoff |
|
|
| --- | --- |
|
|
| RAID 0 for HDD data | Capacity prioritized over disk redundancy; downloaded media can be reacquired |
|
|
| Back up important state | Four application directories covered; media redundancy is not the objective |
|
|
| Mercury public edge | Static public IPv4; home ISP uses CGNAT |
|
|
| No residential public ingress | Owner preference to avoid exposing the home IP |
|
|
|
|
RAID 0 still stores important state alongside media: either HDD failure loses
|
|
the array; recovery depends on working backups. Owner intent is not evidence
|
|
that every important dataset is covered.
|
|
|
|
## Observability
|
|
|
|
| Facility | Current configuration |
|
|
| --- | --- |
|
|
| Host/container monitoring | Beszel hub and host-network agent present |
|
|
| Container logs | Dozzle with Docker socket proxy present |
|
|
| Automatic alerting | None configured |
|
|
|
|
Monitoring does not imply notification delivery. Backup-hook failures,
|
|
stopped services and storage failures require manual detection.
|
|
|
|
## Recovery status
|
|
|
|
No restore test performed. Backup scope is documented in [Backups](backups.md);
|
|
OS, host configuration and named-volume coverage must not be inferred from
|
|
the four-directory plan. Recovery priorities, RPO/RTO and validated bootstrap
|
|
instructions remain unconfirmed.
