DR Plan v3 — Response to Third-Party Reviewers
Two reviewers, two passes. All findings addressed.
Reviewer 1 (Technical DR Specialist)
| Finding | Status | Addressed In |
|---|---|---|
| Failover timing mismatch (5min check can't detect 2min outage) | Fixed | Corrected to 30s checks, 4 failures to trigger = 2min detection, ~3-3.5min actual RTO, 5min committed target |
| Backup standard says daily but not happening | Flagged | Section 3.1 backup matrix shows live vs gap status; P0 items for Docker volume + DB dump automation |
| AI server 92% disk critical | Flagged | P0 action item #1 |
| Memory consolidation data loss risk | Mitigated | S3 backup-before-prune + PROTECT regex expansion + restore procedure documented |
| Tony's Hermes undocumented | Flagged | P1 action item #7 |
Reviewer 2 (Systems Management SME)
| Finding | Status | Addressed In |
|---|---|---|
| S3 single point of failure | Mitigated | Two-destination design (Wasabi us-east-1 primary + Wasabi us-west-2 or Backblaze B2 secondary) |
| Backup frequency vs RPO mismatch | Fixed | Per-data-type RPO: 15min (Hermes state), 24h (Docker/data), 24h backups |
| Restore procedures not detailed | Fixed | Section 6 — per-server runbooks with exact commands |
| Failback under-defined | Fixed | Section 4.4 — 12-step protocol with rollback, no auto-failback |
| No backup restore testing | Fixed | Section 7 — testing schedule with cadence, log template, sign-off table |
| Retention too short (48h snapshots) | Flagged | P1 item #9 — extend to 30 days |
| Backup security not described | Fixed | Section 3.2 — Object Lock, write-only IAM, credential separation |
| Application backup details vague | Partial | Section 2.3 — data paths defined per app |
| Secrets recovery not documented | Fixed | Section 1 — shared dependencies table with credential locations |
| Provider/account outage missing | Fixed | Section 4.5 — netcup account failure scenario |
