10 Barracuda Backup Service Administrator’s GuideDeployment Options OverviewThe Barracuda Backup Service includes a full local data backup, which is performed by the BarracudaBackup Server, and multiple options for offsite data storage. The local backup can be sent to theBarracuda Cloud Storage which replicates data at two offsite locations, to one or more other privateBarracuda Backup Servers for site-to-site replication, or a hybrid approach may be taken where thedata is sent to a combination of the Barracuda Cloud Storage and one or more Barracuda BackupServers. All of these approaches provide the best of both worlds – onsite backups for fast restore timesand secure offsite storage for disaster recovery.Deployment OptionsIn all deployment scenarios, the Barracuda Backup Server is positioned between the firewall and thesystems to be backed up, and the data from your client and server systems is first backed up to theBarracuda Backup Server.As shown in Figure 2.1, the data can then be backed up again to:• Barracuda Cloud Storage, which is maintained by Barracuda Networks.• One or more Barracuda Backup Servers, which ideally would be located in different sites. Thisoption is called site-to-site replication.• Or even a combination of the two.Figure 2.1: Backup Options
