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.
