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 off-host 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 off-host 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.
