# Network Backup and Restore

HashSphere is resilient by design and avoids single points of failure. HashSphere Managed Service also includes backup and restore to support business continuity.

### Backup Scope

For managed service deployments, the following components are backed up on a scheduled basis:

* Consensus node state
* Mirror node data
* Supporting configurations required for service restoration

Backup data is encrypted at rest in cloud storage in a customer-selected region. Restore uses the most recent snapshot to provision replacement components and rehydrate state.

### Downtime Considerations

Network availability during a restore event depends on several factors, including

* The number of nodes affected
* Cloud provider availability during the restore event
* Whether the restore is for a single node or a full-environment recovery
* Transaction volume on the network

Planned maintenance windows and recovery objectives are defined in your service agreement.

### Recovery Objectives

Recovery objectives such as RPO and RTO targets are defined according to the service contract and deployment architecture. Customers should refer to their service agreement for specific commitments.
