Abstract: A method, apparatus, and system for disaster recovery of an IP Multimedia Subsystem (IMS) are provided. The method includes: triggering a redundant Call Session Control Function (CSCF); obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. With the present invention, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.

Abstract: A log processing method, and a related device and system are disclosed. The method includes: obtaining a status message of a storage node cluster (S301), where the status message marks a master storage node (241) of the storage node cluster; sending a first write operation request to the master storage node (241) based on the status message (S302), so that the master storage node (241) agrees on a first write operation after agreeing on a received log with a slave storage node (242) in the storage node cluster (S304); and receiving a feedback message that is sent after the master storage node (241) agrees on the first write operation with the slave storage node (242) in the storage node cluster (S306), where the feedback message includes identification information and a response to the first write operation request, and the identification information is used to indicate the agreed log.
