About the DL3D 1500/3000
Remote replication
Most backup occurs on local devices, making it difficult to deploy
disk backup when you require disaster recovery protection. DL3D
series solutions combine data de-duplication with replication to
decrease the bandwidth required to move backup data over networks
and between sites. This solution makes it practical and cost-effective
for you to replicate backup data over WANs for secure,
network-based disaster recovery protection, and it lets you combine
rapid, local restores with sound disaster recovery protection. With
DL3D series replication, you transmit only unique data from up to 10
sites to a central location using any DL3D model.
DL3D series
replication is an asynchronous, automated background process that
includes the option of AES-128 encryption of data in transit. This
model for protecting the distributed enterprise lets you combine disk,
replication, and tape for an optimal combination of performance,
simplicity, and security.
