[INFO] Downloading Blynk server v0.24.5
[INFO] Creating default configuration
[OK] Installation complete
```

### Update Blynk Server
You can update Blynk Server to the latest version by running:

[INFO] Update v0.24.6 available. Downloading...
[OK] Update complete
[OK] Backup done! You can find it in /home/booteille/.blynkcli/backup/auto-update/b1045268-2f32-4e24-85a3-fb740266d417
```

### Start/Stop/Restart Server
```console
$ blynk-cli server start

$ blynk-cli server status # Display status of Blynk server

$ blynk-cli server stop

$ blynk-cli server restart
```

### Make a backup
You can backup your data folder by typing:
```console
$ blynkcli backup create BACKUP
[OK] Backup done! You can find it in /home/booteille/.blynkcli/backup/BACKUP/cee3acd3-1190-4501-bfc1-ba10423c1a07
```
The backup generated is located in the folder you designed in your Blynk CLI configuration.

As you can see in this example, the generated backup is located under `BACKUP/cee3acd3-1190-4501-bfc1-ba10423c1a07`.
Each backup have an Unique Identifier giving ablity to give the same name to different backups.

You can retrieve backup informations in the file `backups.lock` located in your Backups folder.

Here is what generated the backup we created before:
```console
$ cat /home/booteille/.blynkcli/backup/backups.lock
[
  {
    "name": "BACKUP",
    "uuid": "cee3acd3-1190-4501-bfc1-ba10423c1a07",
    "date": "Thu Jun 01 2017 15:46:50 GMT+0200 (CEST)",
    "server_version": "v0.24.6"
  }
]
```

### Restore from a backup
If you want to restore your data folder from a desired backup, you have to type:
```console
$ blynkcli backup restore BACKUP
[OK] Restored from backup /home/booteille/.blynkcli/backup/BACKUP/cee3acd3-1190-4501-bfc1-ba10423c1a07
```

Now. Admit we have backups under the same name:
```console
$ blynkcli backup restore BACKUP
[WARN] There are 2 backup found with corresponding names:
BACKUP/812de666-6d21-4f36-8877-cc1f775dab73 Thu Jun 01 2017 15:58:44 GMT+0200 (CEST)
BACKUP/cee3acd3-1190-4501-bfc1-ba10423c1a07 Thu Jun 01 2017 15:46:50 GMT+0200 (CEST)
[ERR]  Please, retry with one of these backups
```

Think about the backup you want to restore then type the full name (or at least first characters of uuid) to get your restoration:
```console
$ blynkcli backup restore BACKUP/812
[OK] Restored from backup /home/booteille/.blynkcli/backup/BACKUP/812de666-6d21-4f36-8877-cc1f775dab73
```

You can also restore your backup from the uuid:
```console
$ blynkcli backup restore /cee
[OK] Restored from backup /home/booteille/.blynkcli/backup/BACKUP/cee3acd3-1190-4501-bfc1-ba10423c1a07
```

```console

? Is super admin?  true
[OK] User booteille@booteille.com added

[OK] Property energy set to 15000
