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.

Quantum DXi Deployment

To communicate with Quantum DXi, Veeam Backup & Replication uses two Veeam Data Movers that are responsible for data processing and transfer:

  • Veeam Data Mover on the VMware backup proxy
  • Veeam Data Mover on the Quantum DXi appliance

Quantum DXi does not host the Veeam Data Mover permanently. When any task addresses a Quantum DXi storage, Veeam Backup & Replication deploys and starts Veeam Data Mover on the Quantum DXi system.

Veeam Data Mover establishes a connection with Veeam Data Mover on the VMware backup proxy, enabling efficient data transfer over LAN or WAN.

We recommend against enabling encryption for the jobs targeted at the deduplication storage appliance. Encryption has a negative effect on the deduplication ratio. For more information, see Data Encryption.
