Our main service is located in one of the UK’s most advanced and reliable data centres (it is also a carbon neutral data centre).
In terms of server configuration we have at least two of every key server/service (webserver, database server etc) for redundancy with automated failover should a machine fail. This is backed by a 1 hour hardware replacement SLA should there be an issue.
In terms of total disaster and data centre failure we have the option to restore services from other data centres in a number of locations around the world.
In terms of data backup and retention we have a 3 tier strategy:
- There is a hot replica of the database should the primary fail - failover is automatic
- We take daily backups of all data and copy frequently to an offsite location.
- We maintain a fully redundant transaction log in a separate data centre from which we can replay all transactions from a point in time. This enables a backup to be brought up to a specified time.
