resticprofile schedule copies env-file values into the generated units, which
are 0644, so RESTIC_REPOSITORY (the rest-server basic-auth password included)
was readable by every local user on every restic host.
New playbooks/restic-repository-file.yaml:
- derives /etc/restic/repository (root 0400) from restic.env;
- uploads the profile switched to repository-file, but only when the live
profile's sha matches the repo copy it was edited from (drift guard);
- checks the repository is reachable through the new profile (cat config);
- regenerates the units and verifies they exist and contain no rest:http.
Applied to ana-docker, fv-ml1 (configs/restic/ana-ml2), esh-docker-vm,
esh-vm-db, irv-ml1, nh3-dev and nh3-docker. An independent check across all
eight restic hosts (these seven plus esh-ml1) found 0 leaking units. nh3-docker's
scheduled unit ran a real backup afterwards (snapshot a29b889d). Each host's
URL and passphrase are vaulted as <host>/etc/restic/{repository,password}.
restic.env is kept (root 0600) because the per-host READMEs and the freshness
probe source it. A rotation must update the vault, restic.env and repository.
vm-esh-nas has no infra-ops account. Its in-place migration script is staged
for Prime to run with sudo, and its repo profile is pre-edited to match.
Also mirrors augaman-dev's 401df2d (compose header only). The config hash on
esh-ml1 is unchanged.

# resticprofile config for nh3-docker.
|
|
#
|
|
# nh3-docker is a VM on nh3-pve, so its disk image IS captured by vzdump
|
|
# at the hypervisor layer. This file-level restic is additive: it gives
|
|
# fast per-file restore without mounting the VM image, and ships to the
|
|
# site-local rest-server for location-resilient recovery.
|
|
#
|
|
# Writes to the Synology rest-server at 10.100.50.50:8000 as user
|
|
# `nh3-docker`. The full REST URL (with HTTP basic-auth creds) lives in
|
|
# /etc/restic/repository (root 0400). The client-side encryption passphrase lives in
|
|
# /etc/restic/password.
|
|
#
|
|
# No DB dumps needed. None of the stacks on this host (adguard, dockge,
|
|
# beszel-agent, dozzle-agent, portainer) run a relational DB — AdGuard
|
|
# stores config as YAML, the rest use tiny SQLite state in their volumes
|
|
# which restic captures raw (WAL-mode SQLite recovers cleanly).
