Simulated disaster

 How to simulate DR

Intention

Loss of primary AccountServer

Turn off original AccountServer and promote Slave AccountServer (see Article 1152). Also turn off primary-site VMs to prevent them from taking precedence.

Test that secondary site (a) enables backups to continue and (b) allows customers to restore data.

Loss of StorageServer

Turn off primary StorageServer and promote MirrorServer (see Article 1152).

Test that secondary site (a) enables backups to continue and (b) allows customers to restore data.

When primary StorageServer is turned back on, run Integrity Checks on data on both original SS and promoted mirror. Mirror back to StorageServer and Integrity Check again.
