Techniques discussed herein manage backups of a service cell (SC). Each SC may include a data plane that is isolated from other SCs and comprises a distributed computing cluster (a cluster). A manifest that specifies one or more backup policies may be used to generate a full backup or a partial backup of a data set stored by the cluster. In accordance with the manifest, a signal may be sent to nodes of the cluster. In response, the nodes may transmit locally-stored data (e.g., data segments) to specified locations at a remote storage. The system may maintain a mapping of which segments correspond to data that was stored in the cluster at a time corresponding to a full or partial backup.

Techniques for scalable distributed system backups

Service cells may be utilized to limit the blast radius and reduce the probability of operational incidents (e.g., attacks, load spikes, distributed thrash, and the like). Techniques discussed herein provide any suitable number of service cells, each if which include a management plane and a data plane. A work request that includes an intended state of the service cell can be received and stored. One or more execution tasks can be executed by a management plane of the service cell to bring the data plane to a state corresponding to the intended state. The management plane can monitor the actual state of the data plane with respect to the intended state (e.g., the state requested by a user). Over time, the management plane can make modifications to the service cell to ensure the resources of the data plane are ever in conformance with the intended state requested by the user.
