Abstract: Disclosed are a service disaster recovery backup method, a service disaster recovery backup system and a traffic offload (TOF) node. The service disaster recovery backup method includes: after joining a cluster of TOF nodes, querying each TOF node in the cluster for a service data abstract, a keyword in the service data abstract is an identifier of the first TOF node; when the service data abstract is not queried, undertaking, as an activation node, a local breakout service of service data of the first TOF node, selecting a second TOF node as a backup node in the cluster, and publishing the service data abstract with the identifier of the first TOF node as the keyword in the cluster.
