Cloud Device Example

The following is an example of a Bacula Cloud Device resource:

Device {
  Name = CloudAmazon-dev0
  Device Type = Cloud
  Cloud = MyCloud
  Archive Device = /opt/bacula/backups
  Maximum Part Size = 10 MB
  Maximum File Size = 10 MB
  Media Type = CloudType
  LabelMedia = yes
  Random Access = Yes;
  AutomaticMount = yes
  RemovableMedia = no
  AlwaysOpen = no
}

Note

This is an example of a single device. Usually, you should use an Autochanger having many devices for an optimal performance with concurrent jobs.

As you can see from the above example, the Cloud directive in the Device resource contains the name (MyCloud) of the Cloud resource that is shown below. Note also the Archive Device is specified in the same manner as one would use for a File device, that is, it simply points to a directory.

However, since this is a Cloud Device, instead of the Storage Daemon writing one file per Bacula Volume in this directory, the Storage daemon will create one directory per Cloud Volume here, and in each of these Cloud Volume directories, the Volume parts will be written.

With the above Device resource example, the two cache Volumes shown in figure Bacula Cloud Architecture above would have the following layout on disk:

/opt/bacula/backups
   /opt/bacula/backups/Volume0001
      /opt/bacula/backups/Volume0001/part.1
      /opt/bacula/backups/Volume0001/part.2
      /opt/bacula/backups/Volume0001/part.3
      /opt/bacula/backups/Volume0001/part.4
   /opt/bacula/backups/Volume0002
      /opt/bacula/backups/Volume0002/part.1
      /opt/bacula/backups/Volume0002/part.2
      /opt/bacula/backups/Volume0002/part.3
