Methods and systems for high speed failover in a network are provided. To provide faster Type C GPON redundancy failover, the disclosure herein describes the use of G.8031 1:1 ELPS in a single ended application to ensure path integrity through the network. Single ended 1:1 ELPS means that a network device is configured with 1:1 ELPS and switches paths in the event of disruption of the working communication path without the other underlying transport entities having knowledge of either the ELPS protocol or state machine. ELPS (Ethernet Linear Protection Switching, ITU G.8031) is a standardized method for protection switching between two point-to-point paths through a network, however its application here is quite novel. During a failure on the working path, traffic will switch over to the protection path. Type C PON protection provides a fully redundant path between the OLT and the ONU (2 separate PONs).

A service migration technique moves (migrates) a snapshot storage service of an archival storage system from a primary site to a secondary site in accordance with a planned failover event. The snapshot storage service is configured to provide storage and retrieval of large amounts of snapshots (e.g., recovery points) of application workloads stored as objects on one or more buckets of an object store.

The instantiated storage service instance may then rebuild its service state from the object store, and resume storage and retrieval operations directed to RPs serviced by the instance.
