Backup And Recovery Agent Skill

Backup and recovery

Nobody wants backups; they want restores. The distinction is not pedantic — organizations discover

the difference during the only event that matters.

Recovery objectives and which processes must survive are set by

operations:business-continuity-and-resilience. This skill delivers against them.

Coverage is where it fails first

Most backup gaps are things nobody thought to include: a database somebody stood up outside the

standard process, configuration that only exists in a running system, data in a SaaS platform assumed

to be the vendor's responsibility, or a developer's machine holding the only copy of something.

Reconcile backup coverage against the asset register from

it-operations:it-asset-management on a cadence and treat the difference as a finding. An untested

assumption of coverage is the normal state of affairs.

Note that SaaS providers protect against their failures, not against your deletion or a malicious

insider. Read what the contract actually commits to, rather than what the marketing implies.

The 3-2-1 shape, and why the offline copy matters

Three copies, two media or platforms, one off-site — and, since ransomware, **one immutable or

offline**.

Modern ransomware deliberately targets backups first, using the credentials it found on the way in.

A backup system reachable with production credentials will be encrypted alongside production.

Immutable storage or genuinely offline copies are what survive this, and it is the difference

between an outage and an extinction event.

Retention is a policy decision, not a storage one

Retention has to satisfy operational recovery, legal and regulatory obligations, and data protection

requirements — which pull in opposite directions. Data protection law obliges deletion of personal

data you no longer have a basis to keep, and indefinite backup retention conflicts with that

directly. Settle it with legal-risk:privacy-and-data-protection.

Know how you would satisfy a deletion request that touches backups, before one arrives.

Test restores, or you have nothing

A backup job reporting success proves a file was written. It says nothing about whether the data is

complete, uncorrupted, or restorable in a usable time.

Test on a schedule, restore to a separate environment, and verify the application actually works on

the restored data rather than that the bytes arrived. Record how long it took — that measurement is

the only honest input to an RTO, and it is invariably longer than assumed.

Test the full-scale case at least annually. Restoring one file proves the mechanism; restoring the

system proves the plan.

Never

• Report backup health from job success rather than tested restores.
• Leave backups reachable with production credentials.
• Set retention without reconciling legal obligation against deletion duty.
• Quote an RTO you have not measured by actually restoring.
