The principal goal of a high availability solution is to minimize or mitigate the impact of downtime.

DRBD seamlessly replicates data, transparent to your applications and databases. Service is recovered within seconds when used in combination with Pacemaker.

Precept can provide high availability servers as a managed service.

Keith Osborne, Technical Director of Precept IT:

The principal goal of a high availability solution is to minimise or mitigate the impact of downtime.

The principal goal of disaster recovery is to restore your systems and data to a previous state in the event of a failure or loss of a location.

Basic description – “it’s a replicated RAID 1 filesystem over TCP/IP (network)”.  All data exists on both server simultaneously and should 1 server fail, the other can be brought up with ease to continue the operations of the failed server.
