Sendense Docs

Sendense Components

A concise reference for the appliance, agent, repository and controller roles that make up the Sendense platform.

Component Summary

Use this as the product vocabulary for docs, support conversations and deployment planning.

SHA

Sendense Hub Appliance

Hub appliance

Coordinates protection, recovery, policy, evidence and repository operations across enrolled sites.

SNA

Sendense Node Appliance

Site appliance

Runs close to protected workloads so backup and recovery work can happen through a local site appliance.

SNAgent

Sendense Node Agent

CloudStack host agent

Provides the host-side integration Sendense needs for CloudStack protection, including non-NFS storage layouts.

EBA

Enterprise Block Archive

Repository service

Stores protected VM recovery points with repository efficiency, retention control and recovery readiness.

Controller Template

Sendense Controller Template

Replication controller template

Provides the template used to deploy a Sendense-controlled target-side controller for replication jobs.

Component Responsibilities

Each component has a narrow operating purpose. The architecture page will cover topology and data paths in more detail.

SHA

Sendense Hub Appliance

Hub appliance

Coordinates protection, recovery, policy, evidence and repository operations across enrolled sites.

  • Acts as the hub that Sendense nodes pair with.
  • Keeps job state, policy, inventory context and recovery evidence together.
  • Hosts or coordinates repository services, including local and remote EBA repositories.

SNA

Sendense Node Appliance

Site appliance

Runs close to protected workloads so backup and recovery work can happen through a local site appliance.

  • Pairs with the SHA and follows the policies assigned to its site.
  • Coordinates local backup, restore and replication activity.
  • Keeps site-side data movement close to the workloads being protected.

SNAgent

Sendense Node Agent

CloudStack host agent

Provides the host-side integration Sendense needs for CloudStack protection, including non-NFS storage layouts.

  • Works with the SNA rather than replacing it.
  • Gives Sendense a host-aware view of CloudStack VM disks and protection operations.
  • Helps make CloudStack backup practical across Linstor, ZFS, QCOW2/NFS and mixed storage estates.

EBA

Enterprise Block Archive

Repository service

Stores protected VM recovery points with repository efficiency, retention control and recovery readiness.

  • Supports deduplication, compression, encryption and governed retention.
  • Can be used for local repositories, remote repositories and S3-compatible targets.
  • Keeps repository policy attached to the recovery point instead of scattering it across separate storage tools.

Controller Template

Sendense Controller Template

Replication controller template

Provides the template used to deploy a Sendense-controlled target-side controller for replication jobs.

  • Receives and coordinates replication traffic on the recovery side.
  • Supports target-side recovery workflows without turning every target into a full hub.
  • Keeps replication intake separate from normal production workloads.
