## System architecture

## Components

**Xopero ONE** product as a platform consists of three main components: management service, agent, and storage.

### <mark style="background-color:blue;">Management system</mark>

The main component required to run **Xopero ONE** backup system is called **Xopero ONE Management Service** (abbr. **XMS**). It allows you to comprehensively manage your backups and related resources using **XMS** console with a user-friendly and easy to navigate UI. In on-premise deployment model **XMS** can be installed on almost any computer with **Windows** and **Linux** operating systems or **Docker** environment (even popular **NAS** devices). When it comes to SaaS deployment model, the management service runs on provider's cloud infrastructure.

**XMS** is divided into separate modules, each of them dedicated to a different aspect of backup management:

1. Dashboard
2. Devices
3. Virtual Machines
4. Microsoft 365
5. DevOps
6. Plans
7. Storages
8. Tasks
9. Logs
10. Settings

### <mark style="background-color:blue;">Agent</mark>

The second main component is called **Xopero ONE Agent** and is an application installed on end devices with **Windows**, **Linux**, or **Mac** operating systems. Agent performs all operations requested by **XMS** including data processing (i.e., encryption, compression), connecting to data storage, sending data directly to the storage, and restoring data.

### <mark style="background-color:blue;">Storage</mark>

The last component on the list is storage— **Xopero ONE**, as a multi-storage system, allows you to store your backup data in the cloud (**GitProtect Cloud**, **AWS**, and any **S3** compatible public cloud), locally (NFS, SMB, iSCSI network shares, local disk resources), or in a hybrid environment.
