# 01. Understanding of the concept

Before the installation, it is recommended to understand the concept for more smoth onboarding.

There are three main components:

* Service Layer
* Agent Layer
* Client Layer

The flow is the following:

1. Admin configures rules in the Service Layer and sets the frequency.
2. Agent Layer sends a request to the Service Layer to:
   1. Is it time to process a backup?
   2. If so, give me the rules I should follow.
3. After the backup is processed, it sends the status back to the Service Layer.
4. The developer can download the processed backup.
