Remote Replication
Quantum DXi4000 User’s Guide 7
Remote Replication
Today most backup occurs on isolated devices, making it difficult to
deploy disk backup when disaster recovery protection is required. DXi-
Series solutions use data deduplication and replication to decrease by
up to 50 times the bandwidth required to move backup data over
networks and between sites. This dramatic gain makes it practical and
cost-effective for users to replicate backup data over WANs for secure,
network-based disaster recovery protection, and it lets users combine
rapid, local restores with sound disaster recovery protection.
With DXi-Series replication, users can transmit data from a single site or
multiple sites to a central location using any DXi model. DXi-Series
replication is an asynchronous, automated background process that
includes encryption of data in transit. This model for protecting the
distributed enterprise allows users to combine disk, replication, and
tape for an optimal combination of performance, simplicity, and
security.
