# Backup

## **AIR > Settings > Backup**:

The **AIR Backup** feature allows users to back up system data securely and flexibly through the **UI** or **Command Line Interface (CLI)**. Backups can be stored locally, on **SFTP**, or in **Amazon S3**, and encrypted using **AES256** with a password.

Backups can be performed **immediately** or scheduled at intervals of **every 4 hours, daily, weekly, or monthly**. Users can set the number of backups to retain and the scheduled start time. CLI backup options are available, with detailed instructions in the **Knowledge Base**.

## **AIR > Settings > Backup History**:

This page displays the Backup History available to the AIR console.

## AIR Backup File Naming Convention

AIR backup files use a structured naming format that embeds timestamp and version information directly into the `.abf` filename. This makes it easy to identify when a backup was created and which internal backup schema and AIR console version were used.

### Example Filename

```
