Barracuda Backup uses the VMware vSphere Storage APIs–Data Protection to perform image-level backups of VMware vSphere virtual machines (VMs). If a vCenter server is managing the VMware environment, it is best to configure the data source with the IP address or FQDN of the vCenter server. Configuring the data source using individual ESXi hosts should only be done if a host is standalone or there is no vCenter server managing the environment. See also Storage Pools.
Use the following steps to configure a VMware vSphere data source:
- Log into Barracuda Backup and select the associated Barracuda Backup device in the left pane or in the devices table (for customers with multiple Barracuda Backup devices).
- Go to the Backup > Sources page, and click Add a Computer.
- Complete the following information on the Add a Computer page:
- Computer description
- Computer name
- In the Computer type drop-down menu, select VMware.
- In the VMware Computer Information section, enter the credentials of the account that Barracuda Backup is to use to connect to the vCenter Server or ESXi host.
As a best practice, use a unique account for this integration point and grant it the least level of privileges required, coordinating with the system administrator. This account requires administrative privileges to the vCenter Server or ESXi host. For additional information, see Security for Integrating with Other Systems - Best Practices.
- Click Test Credentials to verify that Barracuda Backup can successfully communicate with the vCenter Server or ESXi host. If the connection is unsuccessful, verify that the credentials are correct.
- Once the VMware data source is configured, click Save.
The Add Data Source page displays. Ensure that Enable CBT is selected. This allows Barracuda Backup to perform incremental backups of the VMs. Finish configuring the backup schedule name, the offsite replication destination, and click Save.
Once the data source is configured, the Schedules page displays. For more information, see Backup Scheduling.
Independent Disks and Physical RDM
Because snapshots from the hypervisor cannot be performed on Independent Disks and Physical Raw Device Mapping (RDM), the Barracuda Backup Agent must be used on these guest VMs to back up these disks. Virtual RDM does support snapshots and is therefore supported by Barracuda Backup.
VMs with Independent Disks configured are backed up by Barracuda Backup, however, the actual Independent Disk itself is excluded from the backup and an error message displays in the backup report. Independent Disks can be configured to exclude a specific disk of a VM from being backed up.
