name	Retention & RPO Compliance
when_to_use	When checking whether actual backup retention configuration and cadence meet a contracted or required policy, rather than assuming the appliance defaults are adequate. Use when: retention compliance, RPO compliance, retention policy, recovery point objective, are we meeting retention requirements, backup contract compliance, retention gap, how far back can we restore.
description	Use this skill to check actual retention configuration and backup cadence against contracted/required retention policy and RPO (recovery point objective) targets — detecting gaps where a client's contract specifies a retention window the appliance isn't actually configured for, or an RPO target the current backup frequency can't actually meet.

Retention & RPO Compliance

Overview

Retention and RPO commitments are made in two places that routinely drift apart: the contract or SOW (what was promised — "1-year retention," "4-hour RPO") and the actual backup system configuration (what's actually happening — a 90-day local retention policy, a nightly-only backup schedule). Nobody discovers the gap until a restore request for month 8 of a promised 12-month retention window comes back empty, or a ransomware event reveals that the "4-hour RPO" client's most recent recovery point is actually 22 hours old. This skill exists to find that gap proactively by comparing what's promised against what's configured — not to audit whether backups are running (backup-job-health) or recoverable (restore-test-verification), both of which are prerequisites to this check actually meaning anything.

Key Concepts

Retention: contracted vs. configured

Retention is the length of time recovery points remain available for restore. The check here is mechanical but frequently skipped: pull the contracted/required retention value (from a documentation platform, contract record, or explicit org policy) and the actual configured retention window from the backup/BCDR tool itself, and compare them directly.

Two distinct gap types matter differently:

• Configured-shorter-than-contracted — e.g. contract specifies 1-year retention, appliance is configured for 90 days. This is a direct compliance failure: the MSP is not delivering what was promised, and a restore request past the configured window will simply fail. Always the higher-severity finding.
• Storage-forced truncation — retention is configured correctly, but the appliance is running out of local storage and silently purging older recovery points before the configured window elapses (see backup-job-health's storage- trending section for the leading indicator). This is a compliance failure with a different root cause and a different fix (capacity, not configuration) — report it distinctly rather than merging it with a simple misconfiguration.

Where a client has no documented retention requirement at all, don't fabricate a default — report the appliance's actual configured retention as informational and flag the absence of a documented requirement as its own gap ("no contracted retention policy on file to check against").

RPO: target vs. achievable

RPO (recovery point objective) is the maximum acceptable amount of data loss, expressed as time — "we can tolerate losing at most 4 hours of data." RPO is not something a backup tool configures directly; it's a target that backup frequency either can or cannot meet. The check is: given the current backup schedule (how often jobs actually run and succeed), what is the realistic worst-case age of the most recent usable recovery point, and does that fit inside the contracted RPO?

• A nightly-only backup schedule cannot meet an RPO tighter than roughly 24 hours (worse, in practice, if the nightly job sometimes fails — the achievable RPO in a failure scenario is however old the last successful recovery point is, not the scheduled cadence).
• Don't evaluate RPO against the schedule alone — cross-reference the job success history from backup-job-health. A job scheduled hourly but failing three runs in a row has an actual achievable RPO much worse than its schedule implies.
• Where no RPO target is documented, report the achievable RPO as informational (derived from schedule + recent success rate) and flag the absence of a documented target explicitly, the same way as an undocumented retention requirement.

Sourcing the "contracted/required" side of the comparison

The contracted or required side of this comparison usually isn't in the backup tool at all — it lives in a PSA contract/service record, a documentation platform entry, or an explicit statement from the person running the check. Don't infer a retention or RPO requirement from the backup tool's own defaults; that would just compare the system to itself and always pass. If no documented requirement can be found anywhere connected, say so plainly rather than treating "whatever is configured" as automatically compliant.

If no backup/BCDR tool is connected

State plainly that retention/RPO compliance cannot be checked: "No backup or BCDR connector is connected through the gateway, so there's no configured retention or backup cadence to compare against requirements." Do not fabricate configured values.

Common Workflows

Portfolio-wide retention/RPO sweep

1. Discover connected backup/BCDR tools via conduit__search_tools.
2. For each client, pull contracted/required retention and RPO values from whatever documentation or contract source is connected (or note that none is available).
3. Pull actual configured retention and recent job-cadence/success data from the connected backup tool(s).
4. Compute gaps: configured-shorter-than-contracted retention, storage-forced truncation risk, and achievable-RPO-vs-target mismatch.
5. Report gaps ranked by severity: contracted-retention violations first, then RPO-target misses, then storage-forced-truncation risk, then informational-only findings (no documented requirement to compare against).

Single-client compliance check

1. Resolve the client's contracted retention/RPO requirement and its connected backup tool(s).
2. Run the comparison for that client only and report the specific gap, if any, in concrete terms (e.g., "contract requires 365-day retention; SIRIS appliance is configured for 90 days — 275-day shortfall").

Error Handling

• No backup/BCDR connector connected: stop and say so; do not fabricate configured retention or cadence.
• No documented contracted retention/RPO found: report the actual configured values as informational and flag the missing requirement explicitly — never assume the configured value is automatically "compliant" because there's nothing to compare it to.
• Retention value not directly exposed by the connector API: derive it from the oldest available recovery point if possible, note that it's a derived estimate rather than a directly-configured value, and say so.

Best Practices

• Always state both sides of the comparison explicitly in output — the contracted/ required value and the actual configured value — never just a pass/fail verdict.
• Distinguish configuration gaps from storage-forced truncation; they have different owners and different fixes.
• Compute achievable RPO from actual job success history, not just the nominal schedule.
• Never treat "no documented requirement" as equivalent to "compliant" — flag the missing documentation as its own gap.

Related Skills

• Backup Job Health — storage-consumption trending here is the leading indicator for storage-forced retention truncation; job success history is required to compute an achievable RPO accurately.
• Restore-Test Verification — a retention window that's configured correctly but has never been restore-tested still leaves open the question of whether those retained recovery points are actually usable.
