In the following diagram you'll find the BackUp configuration for our solution:

In order to show how the backup solution works, we have chose the virtual machine virtual01 which is a server stored in the production environment. The purpose is to provide a virtual machine complete copy, so in case of disaster you'll be able to restore it in another virtualization environment and restore the service as soon as possible. Bacula Daemon Client, the host that has access to the storage where the virtual machine virtual01 is located, carries out the security copy. This daemon is installed in production01, the production environment.

You also have a production environment, where backup01 is located. this virtual machine stores the Bacula Director Daemon, which manages and plans security copies. This configuration is located in /apps/bacula/etc/bacula-dir.conf, where you'll find the necessary information to carry out the security copies.

You finally need the  Bacula Storage Daemon. This daemon stores the security copies in a dedicated storage and is installed in the virtual machine development01. This host must have access to the storage where the security copies are located, because it has to carry out security copies in  backupstorage (NAS storage with RAID 5 disks).
