Quantum DXi
You can use Quantum DXi appliances as backup repositories.
Quantum DXi Deduplication
Quantum DXi appliances use Quantum’s patented data deduplication technology. During backup data transfer, Quantum analyses blocks in a data stream. Instead of copying redundant data blocks Quantum uses reference pointers to existing blocks on the storage device.
Backup Infrastructure
To communicate with Quantum DXi, Veeam Backup & Replication uses Veeam Data Movers. They connect to each other, process data and transfer it over LAN or WAN.
Veeam Backup & Replication uses the following Veeam Data Movers:
- Veeam Data Mover on the Quantum DXi appliance
- [For Hyper-V on-host backup] Veeam Data Mover on the Hyper-V host
- [For Hyper-V off-host backup] Veeam Data Mover on the off-host backup proxy
- [For VMware vSphere] Veeam Data Mover on the VMware backup proxy
Quantum DXi hosts Veeam Data Mover permanently. Veeam Backup & Replication installs the persistent Veeam Data Mover during the initial connection to the appliance and then reuses the data mover when needed. This eliminates the need for runtime components and reduces potential security exposure.
Note |
Since Veeam Backup & Replication version 12, deduplicating storage appliances use the TLS connection. You can disable the TLS connection by editing the configuration file. For more information, see this Veeam KB article. |
For more information and recommendations on working with Quantum DXi, see this Veeam KB article.
Configuration on Quantum DXi Side
Create at least one share on each Quantum DXi appliance. Enable VDMS (Veeam Data Mover Service) for the created share. Leave default compression and deduplication settings for the share. For more information, see Quantum DXi documentation.
Note |
When adding credentials for Quantum DXi, use only lower case symbols for the user name. |
Configuration on Veeam Backup & Replication Side
On the Veeam Backup & Replication side, do the following:
- Add credentials for the Quantum DXi user account you created in the previous steps. For more information, see SSH Credentials.
Note |
Make sure that you use the UPN format for an Active Directory account user name (for example, john.doe@domain.local), and enter the user name in lowercase letters only. |
In the Credentials window, you must specify the SSH port that will be used to connect to the appliance.
The port number depends on the number of a Veeam container that you want to use. To see the available containers, go to Configuration -> System -> App Environment.
| Port |
|---|---|
Container 1 | 11000 |
Container 2 | 12000 |
Container 3 | 13000 |
Container 4 | 14000 |
Container 5 | 15000 |
Important |
You must use different containers if you connect to the Quantum DXi appliance from different backup servers. Each backup server can use only one container. |
- Add the Quantum DXi appliance as a managed Linux server using the created credentials. For more information, see Adding Linux Servers.
At the Access step of the wizard, select the added SSH credentials from the drop-down list and click Optional components and advanced connection settings to configure connection ports:
- To configure a port for a component, select the required component and click Edit. In the Component port window, specify the port number and click OK to save the changes.
- In the Data transfer options section, provide a range of ports that will be used as transmission channel.
The ports differ depending on the container to which you plan to connect.
| Installer Service | Data Mover Service | Data Transfer |
|---|---|---|---|
Container 1 | 11001 | 11002 | 11003-11999 |
Container 2 | 12001 | 12002 | 12003-12999 |
Container 3 | 13001 | 13002 | 13003-13999 |
Container 4 | 14001 | 14002 | 14003-14999 |
Container 5 | 15001 | 15002 | 15003-15999 |
- Configure a Quantum DXi backup repository. For more information, see Adding Deduplicating Storage Appliances.
- Point the repository at the created share on the Quantum DXi appliance.
- Set the Limit maximum concurrent tasks to N option to 10 tasks. This limit can be tuned up or down with assistance from Quantum DXi Customer Support.
Backup Job Configuration
For the backup jobs, use the forward incremental backup method. We recommend that you enable synthetic full and schedule them to run on a weekly basis. Also, enable active full backups and schedule them to run on a monthly basis. For more information, see Backup Settings in VMware vSphere backup jobs and Backup Settings in Microsoft Hyper-V backup jobs. We recommend that you do not enable encryption for the jobs targeted at the deduplication storage appliance. Encryption has a negative effect on the deduplication ratio. For more information, see Job Encryption.
