backup/backup.sh (operator orchestrator) + backup-remote.sh (VM assembler) produce
a CONTRACT_004 bundle in RustFS foundation-backups/<TS>/ and replicate it to the
offsite olsitec-foundation bucket: pg_dumpall, forgejo git repos (tar.zst), vault
raft snapshot, pulumi state, rustfs blobs, MANIFEST.json (sha256 + restore order).
The timestamp is caller-supplied (§4.1); secrets travel on stdin (never argv,
ADR-007); mc runs containerized. restore.sh + restore-remote.sh are the §4.6
verifier: pull a bundle (rfs or offsite), check MANIFEST shas, then
NON-DESTRUCTIVELY reconstruct into scratch resources and assert (postgres users>0,
olsitec/foundation.git present, vault snapshot non-empty).
Live on cx33 Helsinki: bundle written to RustFS + offsite; restore-verify PASSES
from BOTH sources (forgejo.user rows=2, repo present, 16KB vault snapshot).
Known gap: at-rest age encryption (§4.3) not yet applied — both destinations are
private/access-controlled; adding age (generate key + encrypt-before-upload) is
the next hardening. Acceptance T12 met.
