Our infrastructure is backed up to a separate data centre from our production availability zones. Additionally, each of our availability zones remain self-contained, so if there is an outage that affects one zone it will not affect customers in another one. Central services are replicated cross-zone for further fault tolerance.
We backup our infrastructure including environment configuration and supporting infrastructure configuration (ie Zettagrid?s core DNS, DHCP, AD, vCloud-Director Cells, vCenters, SQL DB Clusters, etc) and Customer machine configuration.
Zettagrid does NOT backup your virtual machines unless you purchase a Zettagrid Backup service. You are responsible for backup of data from your virtual machines and implementing the appropriate retention policy.
