Deploy a Barracuda Backup Virtual Appliance

Last updated on 2024-05-22 11:11:15

To create a successful data protection and disaster recovery plan, Barracuda Networks strongly recommends following the 3-2-1 backup rule:

3 – You must have at least 3 copies of your data; the original production data and 2 backup copies.
2 – You must use at least 2 different types of media to store the copies of your data, for example, your production storage and the local Barracuda Backup virtual appliance data storage.
1 – You must keep at least 1 backup offsite, for example, in the cloud or in a remote site.

For deployment of the Barracuda Backup virtual appliance (Vx), Barracuda Networks recommends a completely separate virtual infrastructure from that of the data in which the Vx will be protecting. This means running in a separate virtual cluster, dedicated virtual host, and/or separate storage from the production environment. This will help avoid situations where the production virtual infrastructure or storage fails or is impacted by ransomware and impacts both the production virtual machines and the Barracuda Backup virtual appliance.

The following sections walk you through the process of deploying a Barracuda Backup Virtual (Vx) appliance.

System Platform Requirements

Barracuda Networks provides the following types of virtual images for the Barracuda Backup Vx deployment.

Table 1. System Platform Requirements

Image Type	Platform	Version
OVF	VMware	See Virtual Infrastructure for supported versions.
VHD	Microsoft Hyper-V	See Virtual Infrastructure for supported versions.

System Resource Requirements

The most common mistake when designing an environment for Barracuda Backup Vx is to size only for capacity as opposed to sizing for capacity and performance. Tasks such as backup, offsite replication, data restoration, and purging can use a significant amount of system resources. When considering a Barracuda Backup virtual deployment, it is best to consider the use cases of the Backup Vx in addition to needed storage.

Table 2. vCPU Recommendations

Backup Volume	Minimum Recommended vCPUs	High Performance Recommended vCPUs
0-2 TB	1 vCPU	2 vCPUs
2-6 TB	2 vCPUs	4 vCPUs
6-16 TB	4 vCPUs	8 vCPUs
16-32 TB	8 vCPUs	16 vCPUs
32-100 TB	16 vCPUs	32+ vCPUs

Table 3. RAM Recommendations

Backup Volume	Minimum Recommended RAM	High Performance Recommended RAM
0-1TB	2 GB	4 GB
1-4 TB	4 GB	8 GB
4-12 TB	8 GB	16 GB
12-16 TB	16 GB	32 GB
16-24 TB	32 GB	64 GB
24-48 TB	64 GB	128 GB
48-100 TB	128 GB	256+GB

Storage Recommendations

Any storage infrastructure consisting of Local/Direct-Attached, SAN, and NAS
Storage with inadequate throughput, read, and write speeds will suffer
Servers with software RAID, slow NAS, and low-RPM drives will yield poor performance

Notes and Considerations

Barracuda Backup utilizes memory (RAM) for database queries during backup, restore, and offsite replication. Barracuda Networks highly recommends following the recommended minimum resources for memory in the RAM Recommendations table above.
Barracuda uses CPU resources for hashing blocks during deduplication, compression for offsite replication, and rehydration of data during restoration. Barracuda Networks highly recommends following the recommended minimum resources for vCPUs in the vCPU Recommendations table above.
At a minimum, memory resources should be dedicated (reserved). It is also recommended that the CPU be dedicated to Barracuda Backup Vx and not shared with other virtual machines on the host. This aligns with VMware and Microsoft’s recommendations for virtualized Microsoft Exchange Server and SQL Server implementations.
A separate data store is recommended for use with the virtual appliance due to disk I/O constraints or an entirely separate storage server/environment altogether from the production environment.
Other system components such as network and storage need to be sized accordingly to prevent them from becoming a bottleneck.
It is important that snapshots are not used on the Barracuda Backup Vx appliance. Even if data is not being replicated to the Barracuda Cloud, configuration data is still sent to Barracuda so that the unit can be managed. Reverting to a previous state using snapshots can potentially cause loss of data and unit corruption. Independent disks are the default selection and highly recommended to avoid snapshots.
Use only a single attached virtual volume when deploying the Barracuda Backup Vx appliance. When expanding Barracuda Backup Vx capacity, expand only the current volume. Adding and expanding a new volume can potentially cause loss of data and unit corruption.
All Backup Vx disk, vCPUs, and RAM can be adjusted later by shutting down the system properly and making the necessary changes through the hypervisor.

How to Set Up a Barracuda Receiver Vx

Barracuda Backup Vx includes one-way basic software replication to a Barracuda Receiver Vx. A single Barracuda Receiver Vx license is included with each Barracuda Backup Vx subscription for one-way replication.

You can use the Barracuda Receiver Vx as a replication target and for restores. With a Receiver Vx subscription, you can pair a physical appliance and a Barracuda Receiver Vx, one-to-one. Additionally, it can be used for site-to-site replication or in conjunction with Barracuda Cloud Storage for multiple offsite copies.

To generate a license, link to your account, and provision the Barracuda Receiver Vx:

Log in to Barracuda Backup, go to the Backup > Replication page, and click Add Target.
Once you click Activate, the Barracuda Receiver Vx license token for provisioning your virtual machine is generated, and then activates and links the system to your Barracuda Cloud Control account.
In the Site-to-Site Replication section, click Activate:
The confirmation dialog box displays:
Click Proceed to activate and link the Barracuda Receiver Vx to your account. The license token displays on-screen.
Use the license token to provision your Barracuda Receiver Vx using the same virtual image used to deploy the Barracuda Backup Vx:
After provisioning the Barracuda Receiver Vx and booting the system, configure replication settings on the Backup > Replication > Add Target page using the destination IP address, serial number, and replication code. This information is located on the Barracuda Receiver Vx Replication page:
The Barracuda Backup Vx is now ready to replicate data.

Barracuda Backup Vx Replication Options

The Barracuda Backup Vx appliance can replicate data to Barracuda Cloud Storage for offsite disaster recovery or site-to-site for basic software replication to a virtual or physical Barracuda Backup appliance.

Table 1. Barracuda Backup Vx Replication Options

Barracuda Backup Vx can replicate to one or more destinations.

Replication Target	Direction	Type
Barracuda Cloud Storage	One way	Site-to-cloud
Barracuda Backup Appliance	One way	Site-to-site
Barracuda Backup Vx	Bidirectional	Site-to-site
Barracuda Receiver Vx	One way	Site-to-site

Barracuda Cloud Storage

No additional configuration is necessary to set up Barracuda Cloud Storage. Each Barracuda Backup Vx is preconfigured with Barracuda Cloud Storage as a target within Backup > Replication and is enabled by default for users who have either purchased or are evaluating the service:

Data replicated to Barracuda Cloud is stored encrypted on geographic and locally redundant storage with billing applied against the amount of storage hosted offsite, after deduplication and compression. Leverage Barracuda Networks' scalable cloud architecture to avoid the complexity and risk of allocating and managing offsite storage sites. Contact your Barracuda Networks partner or Barracuda sales representative for more information.

Barracuda Backup Appliance

You can configure the Barracuda Backup Vx appliance to replicate one-way to a Barracuda Backup appliance, model 490 and above, for site-to-site replication.

Use this option in multi-site environments with mixed physical and virtual Barracuda Backup appliances or in an environment with a physical Barracuda Backup appliance and two or more locations. Ensure that the Barracuda Backup appliances have suitable storage and are sized appropriately to host data being replicated to it as well as the data locally backed up to the appliance.

Barracuda Backup Vx

You can configure the Barracuda Backup Vx appliance to replicate bidirectionally to another Barracuda Backup Vx or to a Barracuda Backup appliance.

Use this option in environments where two or more sites host primary backed up data, and where site-to-site replication is preferred. This is the recommended method for site-to-site replication for the Barracuda Backup Vx as the virtual appliance storage can be scaled to meet storage demands over time.

Each Barracuda Backup Vx can be set up as a replication target for one-to-one replication between virtual appliances or to a physical device as a replication pair. Note that many-to-one replication is not available with the Barracuda Backup Vx appliance.

For optimum performance, ensure that the appliance at each location is set up with the minimum system requirements as described in the tables in the System Resource Requirements section of this article. See Configure an Offsite Replication Destination for details on setting up a site-to-site replication target.

Barracuda Receiver Vx

The Barracuda Receiver Vx is included with the Barracuda Backup Vx subscription for basic software replication and can be set up as a replication target and can perform restores. With a Receiver Vx subscription, you can pair a physical appliance and a Barracuda Receiver Vx, one-to-one.

Use this option in environments where an offsite location can host the virtual appliance as a storage target but does not have primary data to back up, or in environments where you want to replicate the Barracuda Backup Vx within the same site. You can use the Barracuda Receiver Vx in conjunction with Barracuda Cloud Storage for two offsite copies. The Barracuda Receiver Vx has the same benefits as the Barracuda Backup Vx. You can add the Barracuda Receiver Vx to a physical appliance.
