Definition of Failback in Network Encyclopedia.

What is Failback?

Failback, in clustering technology, is the action of moving resources back to a node (a computer in a cluster) that has failed. This is sometimes known as «rebalancing the workload».


How it works

Suppose you have a cluster that has two nodes, each containing different resources. If Node A experiences failure, failover occurs and the workload of Node A (its set of resources) is transferred to Node B. When Node A reboots, it checks with Node B to see which resources are running on Node B and discovers that some of these cluster groups would “prefer” to reside on Node A.

At this point failback occurs, and the preferred groups are moved from Node B back to Node A. Failback might be configured to occur immediately or at a scheduled time if access to resources is low.

In Microsoft Windows NT 4 Enterprise Edition, Microsoft Cluster Server (MSCS) sets up and controls clustering. In Windows 2000 Advanced Server, the Cluster service makes these functions available.

Public Key Infrastructure (PKI)

Public Key Infrastructure, also known as PKI, is a set of services that support the use of public-key cryptography in a corporate or public setting. A public key infrastructure (PKI) enables key pairs to be generated, securely stored, and securely transmitted to users so that users can send encrypted transmissions and digital signatures over distrusted public networks such as the Internet.

Digital Signature

Digital Signature is an electronic signature that you can use to sign a document being transmitted by electronic means such as e-mail. Digital signatures validate the identity of the sender and ensure that the document they are attached to has not been altered by unauthorized parties during the transmission.
