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 esh-vm-db.
|
|
#
|
|
# Two-database host (Postgres 15 on :5432, MongoDB on :27017). Small
|
|
# VM on an ESH hypervisor; backed up at VM-image level by PBS-ANA via
|
|
# its hypervisor. This restic profile captures:
|
|
#
|
|
# 1. Host config (/etc, /root) — fast config recovery without
|
|
# waiting for VM-image restore
|
|
# 2. Per-DB dumps via pre-backup hook — pg_dumpall + mongodump,
|
|
# written to /var/lib/restic/stage/ and included in the restic
|
|
# snapshot. Gives us DB-level restore granularity alongside the
|
|
# VM-image restore from PBS.
|
|
#
|
|
# What's DELIBERATELY NOT in source:
|
|
# - /var/lib/postgresql — raw live PGDATA. Inconsistent if captured
|
|
# while postgres is running; pg_dumpall above covers this.
|
|
# - /var/lib/mongodb — same reasoning; mongodump covers it.
|
|
#
|
|
# Writes cross-site to rest-server-ana (10.250.50.70:8000). No local
|
|
# NH3-style rest-server on the ESH side; esh-docker-vm and vm-esh-nas
|
|
# also use rest-server-ana, so this follows fleet pattern.
