Scripts adapted from FreeBSD Home NAS setup. Also performs periodic zpool scrubbing. +The **`zusb` quarterly backup** (`/opt/snonux/bin/backup/backup`, which travels on the `zusb` pool — see [USB Key Mounting](usb-keys.md) → "Removable backup pool (`zusb`)") also uploads to the same S3 Glacier Deep Archive bucket (`s3://org-buetow-backup/<host>/`). Both workflows need the AWS CLI on the host that runs them. + +### AWS CLI setup on a FreeBSD host + +Install the `awscli` package.

The **credentials ride on the `zusb` pool** at `/opt/snonux/secrets/aws.credentials` (INI: `[default]` + `aws_access_key_id` + `aws_secret_access_key`), so on any host that has `zusb` imported (i.e. `/opt` mounted) you only need the config file and a symlink — the secret is not duplicated on host disks and is not in git: + +```sh +sudo mkdir -p /root/.aws && sudo chmod 700 /root/.aws +printf '[default]\nregion = eu-central-1\n' | sudo tee /root/.aws/config >/dev/null +sudo chmod 600 /root/.aws/config +sudo ln -sf /opt/snonux/secrets/aws.credentials /root/.aws/credentials +``` + +Because the credentials are a symlink into `/opt` (`zusb/data/opt`), `aws` only resolves them while `zusb` is imported on that host. That is fine for the quarterly backup workflow (load `zusb` → run backup → export `zusb`); it is **not** suitable for the `zdata` daily-cron S3 backup on an f-host that does not normally have `zusb` imported — that host would need its own credentials copy (out of scope here). + +Verify (read-only): + +```sh +aws --version +aws sts get-caller-identity # expect Arn arn:aws:iam::634617747016:user/org-buetow-backup-user +aws s3 ls s3://org-buetow-backup/ # expect the per-host prefixes (e.g. t450/) +``` + +Installed 2026-07-20 on f1 (`py312-awscli-1.42.44`), matching the t450 setup (`py39-awscli-1.29.81`, same `/root/.aws/config` region and the same credentials symlink). + ## Local-Path Storage for SQLite Workloads Some k3s workloads use `local-path` (k3s default storageClass) instead of NFS for |
