Methods and apparatus are provided for protection of state information for an auxiliary storage service in a microservice architecture. An exemplary method comprises generating a snapshot of state information of an auxiliary storage service on a given storage node in a storage cluster comprised of a plurality of storage nodes; and providing the snapshot to M protector storage nodes within the plurality of storage nodes in the storage cluster, wherein the M protector storage nodes comprises a snapshot manager node and M−1 additional protector storage nodes, and wherein the M protector storage nodes are selected based on a hierarchical ranking of available storage nodes within the storage cluster arranged in a predefined configuration relative to the given storage node. The predefined configuration of the plurality of storage nodes can be, for example, a protection ring comprising a first M−1 online storage nodes that follow the snapshot manager node in the protection ring in a predefined direction.
