CloudBoot backup servers are CloudBooted KVM Compute resources that can be be used as backup servers. Follow the step-by-step instructions provided in this chapter to configure CloudBoot backup servers in your cloud.

 
To create a CloudBoot backup server:

1. Update CloudBoot and CP server RPMs:

   Code Block
   yum update onapp-store-install yum update onapp-cp-install

2. Configure CloudBoot settings:

   Code Block
   /onapp/onapp-store-install/onapp-store-install.sh

3. Create new CloudBoot compute resource: at the first step of the creation wizard choose the type - Backup (CloudBoot Provisioning and Backup Resource). Refer to the Create CloudBoot Compute Resource section of this guide for details.

4. Go to your Control Panel's Settings menu, then press Compute Resources icon.
5. Click the Add New CloudBoot Compute Resource button. 
6. In wizard menu click Backup (CloudBoot Provisioning and Backup Resource). 

7. Select right MAC address of it.

8. Fill in the form that appears:

   • Label - give the compute resource a name
   • Pxe IP address - select an IP address for this compute resource from the address pool available
   • Enabled - move the slider to the right to allow VSs to be installed/booted on this compute resource
   • Compute Zone - select the compute zone, to which this compute resource will be assigned, from the drop-down list
   • Custom Config - specify any custom commands you want to run when compute resource is booted

9. At this step, specify the Backup Server properties:
   
   

   • Label - give your backup server a label
   • IP address - enter the IP address of a Compute resource you have created at step 1
   • Backup IP address - add a provisioning network IP address
   • Capacity - set the backup server capacity (in GB)
     
     
10. Then, you shouldn't assign any drive, but it needs right NIC to be applied to the storage network.

11. After that, assign your backup server to the backup server zone.

    If you intend to attach LVM-based storage and create backups, you should also add the IP address of the KVM Compute resource added in step 1 in the 'Backup IP address' field of each of your compute resources.

Further steps:

1. Format and mount the local storage:
   
   
   1. SSH to the backup server

   2. Format the storage with your preferred filesystem type, e.g.:

      Code Block
      bash#> mkfs.ext4 /dev/sda

   3. Make folder for backups if it does not exist
      

      Code Block
      bash#> mkdir /backupstorage

   4. Mount the storage to /onapp/backups:
      

      Code Block
      bash#> mount /dev/sda /backupstorage

   5. Make folder for storing templates:
      

      Code Block
      bash#> mkdir /backupstorage/templates

   6. Make folder for storing backups:

      Code Block
      bash#> mkdir /backupstorage/backups

   7. Create symbolic links in /onapp:
      

      Code Block
      bash#> ln -s /backupstorage/backups /onapp/backups bash#> unlink /onapp/templates bash#> ln -s /backupstorage/templates /onapp/templates bash#> ln -s /onapp/tools/recovery /data

   8. Add the following to custom config file:
      

      Code Block
      mkdir /backupstorage mount /dev/sda /backupstorage ln -s /backupstorage/backups /onapp/backups unlink /onapp/templates ln -s /backupstorage/templates /onapp/templates ln -s /onapp/tools/recovery /data

2. Update the database so that the location of the templates is known:

   a. Find the database password:

   Code Block
   cat /onapp/interface/config/database.yml |grep password

   b. Open the onapp database in MySQL: 

   Code Block
   bash#> mysql -p bash#> use onapp;

   c. Find the ID of the backup server:

   Code Block
   bash#> select * from backup_servers;

   d. For all of the templates, set the required backup_server_id:

   Code Block
   bash#> update templates set backup_server_id='[your_id]';

3. To download the base templates during the installation to your Control Panel, download and run the following script:
   

   
   

   Code Block
   bash#> wget http://downloads.repo.onapp.com/get_template.sh bash#> /bin/sh get_template.sh
