Coldharbor

Backup and DR

A backup you have not restored is a rumour

Coldharbor takes immutable copies, keeps one of them air-gapped, and then restores them on a schedule — automatically, into a sandbox, with a report you can hand to an auditor.

The four things that actually matter

Immutability that is not a checkbox

Every copy lands in object-lock compliance mode. An attacker with your console credentials, your API keys and our support team's cooperation still cannot shorten a retention.

Restore drills, automatically

We boot your backups into an isolated sandbox on a schedule you set, check the services come up, and send you a report. Failures page you, not us.

Air-gapped third copy

3-2-1-1-0: three copies, two media, one off site, one air-gapped, zero errors after verification. The air-gapped copy is pulled, never pushed.

An RTO you can quote

Recovery time is measured from real drills, per workload, and shown in the console. Not a number from a sales deck.

Ransomware

What happens on the worst day

The recovery playbook is not a document, it is a button — and it has been pressed in anger 31 times by our customers in the last two years.

  • Detect: entropy and change-rate anomalies flag encryption within one backup cycle
  • Isolate: the affected agent is quarantined; existing copies become read-only immediately
  • Choose: a clean recovery point is proposed from the last passing drill, not the last backup
  • Restore: boot into an isolated network, verify, then cut over

Questions from IT managers

Snapshots live on the same storage as the thing they protect and can be deleted by whoever compromises it. That is a rollback feature, not a backup.
