Unlimited Cloud Storage
Barracuda Cloud Storage is available by purchasing Unlimited Cloud Storage. Unlimited Cloud Storage allows you to store all of your content without having to manage storage usage limits. There are no data transfer fees, for example, PUTS, GETS, UPLOAD, DOWNLOAD. You can also enable offsite vaulting which leverages Barracuda's Cloud Storage service to offload up to 12 monthly and 7 yearly revisions to strictly cloud storage, freeing up disk space on your local Barracuda Backup appliance.
Unlimited Cloud Storage mirrors content offsite based on your retention policies. As noted above, you can enable offsite vaulting to purge data from the local cache. Contact your Barracuda Sales Representative for Unlimited Cloud Storage pricing.

Each Barracuda Backup appliance can send data to one or more other Barracuda Backup appliances.
