ISO:Business Continuity and Disaster Recovery

From Hornbill
Jump to: navigation, search

Hornbills configuration of servers\services has been planned to ensure that their is no single point of failure, all services have fail over servers or spare capacity.

Business Continuity and Disaster Recovery plan

Hornbill are committed to providing customers with access to their subscribed services and data even in the event of a emergency or disaster. Our plan is designed so that in the worst possible case customers will be without access to instances for the minimum time possible whilst a full restore is carried out to a secondary data centre.

In the event of a disaster or high impact issue the Cloud team have the option to invoke the Emergency plan. Once started this ensures additional resources are provided to the cloud team and non-critcal work is suspended.

The plan is tested against 2 main scenarios at least once every year to ensure that in the case of Loss of Hornbill offices or Loss of Data Centre we are able to continue to provide all services as expected.

Testing is performed remotely and its objectives are to show that we can continue to provide all services to existing customer, recreate the contents of 1 or more data centres in time specified in our SLAs and begin to provide all back end services used by Hornbill offices by the end of 1 working day.

Any outcomes\failings in the tests are noted and addressed within 1 month of the exercise and if necessary a new test scheduled.

A redacted version of the DR Plan is available on request.

Backups

All instances are replicated real time to a central server located within the same geographical location as the live instance and then nightly backups of these are taken and stored within S3 (again within same geographical location) every evening. The backup process is monitored\tested to ensure successful upload automatically and a manual restore of a random instance performed every month to ensure data integrity. In the event of the emergency plan being activated and needing to restore, we will first attempt to use the live replication and should that be unavailable (Unlikely) we would revert to the last nightly backup.
