{{ menu }} → {{ settings }} → System → Backup → Create Backup

![Backup creation dialog](images/BackUp-Create.png)

**Backup creation** is accompanied by a **progress indicator**.

```{important}
**Backup creation time** depends on the ENC collection size, route collection, volume of manual corrections and user chart, and may take **a significant amount of time**.
```

```{note}
**The backup creation process** runs in the **background** and does not restrict the navigator from performing ECDIS operational tasks.
```

### Restoring from a Backup

{{ menu }} → {{ settings }} → System → Backup → {{ restore_backup }}

```{important}
**When restoring**, all previously installed charts, certificates, routes, settings, manual corrections, and user objects **will be replaced with data** from the backup.
```

```{note}
**Restoring a backup** requires a subsequent ECDIS reboot.
```

```{important}
**Restoring a backup** may take a significant amount of time depending on the volume of previously saved data.
The backup restoration speed also depends on the USB port class and USB medium.
```

### Managing Backups

#### Number of Copies
- **The number of backups** is determined by the ECDIS hard disk capacity

#### Deleting Old Copies
- **With long-term storage**, backup data becomes outdated
- **It is advisable to forcibly delete** old backups

```{tip}
**It is recommended to regularly create** backups before important updates or system changes.
```

```{tip}
**It is recommended** to store ECDIS backups on external storage media.
```
