How does Deduplication work with Remote Replication?
CommVault Simpana software is built from a common set of re‐usable services which have been optimized for
modern data management. These include advanced data backup and recovery, archive, encryption, compression
and deduplication. Each individual service and capability offers its own compelling advantage. In combination, the
benefit for data management is compelling.
Organizations planning for data centralization from remote sites and systems are concerned with network
efficiency. To address these concerns, CommVault Simpana software offers a full range of capabilities designed to
ensure that only the data which must be replicated is sent across Wide Area Network connections. By combining
advanced capabilities for backup and archive together with compression, encryption and deduplication,
CommVault Simpana software provides better efficiencies for transmission of any type of data across WAN
connections than is otherwise achievable.
The effect of efficient backup: CommVault Simpana backup software includes capabilities for selecting
incremental and differential data for protection. Synthetic Full capabilities make this even more efficient, and is
often suitable for protecting data across WAN connections when the rate of change on remote data is low.
The effect of archive: CommVault Simpana archive capabilities further reduce the burden on data backup by
removing static and less frequently used data from primary stores. Removing this data to secondary storage not
only frees up the primary disk and speeds application performance, it also reduces the amount of data that must
be backed up, preserved nightly or weekly, and rotated offsite for disaster recovery.
The effect of compression: Depending on the type of data, compression algorithms can often reduce the size of
the data being sent over networks – sometimes more than deduplication. CommVault Simpana software offers
the ability to combine use of compression with deduplication, for maximum network efficiency for all types of
data.
The effect of encryption: CommVault Simpana software includes advanced encryption algorithms including AES
256, Blowfish and other popular encryption methods. These are offered for use in combination with data
compression and deduplication, to ensure that data sent across WAN connections does not present a security risk.
The effect of deduplication: CommVault Simpana offers File Deduplication capabilities for file, document and
email attachment deduplication. When applied to data at remote sites, deduplication removes any duplicate data
before that data is sent on WAN connections. Uniquely designed for use with compression and encryption,
CommVault Simpana deduplication offers better efficiencies for transmission of any type of data across WAN
connections than is otherwise achievable.
