The Acronis®Backup & Recovery 10 Deduplication option allows seamless
integration of data deduplication in the backup process. Available as an
option with any of the Acronis Backup & Recovery 10 advanced products,
it is integrated for ease of use and will reduce storage costs and network
bandwidth utilisation. Priced for SMB, Acronis has brought this cost saving
technology to organisations that, until now, could not afford the significant
implementation investment required.
The resulting benefits to all size organisations are:
Reduction of data up to 90% with deduplication and compression, saving•
storage space
Elimination of data deduplication-specific hardware saving capital expense•
Reduction of network traffic resulting in higher communications efficiencies•
The Acronis®Backup & Recovery™10 family of products simplify and automate
backup and disaster recovery of Microsoft and Linux workstations and servers
in physical and virtual environments. Based on patented disk imaging and
bare metal restore technologies, these products are the next generation of
Acronis®True Image.
Significant storage and network savings through data deduplication
Eliminating duplicate copies of data from multiple computers during the
backup process results in substantial storage and network cost savings. The
Acronis Backup & Recovery 10 Deduplication option provides affordable file
and block-level software deduplication functionality for both workstations
and servers, so organisations of all sizes can make better use of their storage
infrastructure and save costs.
Data deduplication managed from a central location
Unlike compression, which reduces the size of a single backup image or file,
data deduplication actually eliminates redundancy data across all workstations
and servers scheduled to be backed. For example, when full weekly backups are
performed with a data retention period of 12 months, the “traditional” backups
will contain a significant amount of duplicated data. However, when including
data deduplication in the backup process, only the unique data are stored on an
Acronis Storage Node. Depending on type of data, the recurrence of data change,
and the data retention policy, it is possible to achieve, using data deduplication,
compression ratios of 1:20 or higher. The diagram illustrates how deduplication
works when used as part of an organisations backup and restore process. With the
Acronis Backup & Recovery Deduplication option, and based on policy set by the
organisation, deduplication can take place at the source (machine being backed up)
or the target (receiving Acronis Storage Node).

Key Features
Deduplication Options
Deduplication for image backup: Acronis Backup & Recovery 10 is the only backup software that provides deduplication for image based
backup. Only unique 4k blocks of data are stored on a Storage Node.
Deduplication for file backup: For file-level backup only unique files are stored on a Storage Node.
Deduplication at source: In addition to savings of storage capacity for backups, deduplication on a Client provides the benefit of reducing
the network traffic because only unique blocks or files are sent from a Client to a Storage Node.
Deduplication at target: If CPU on a backup Client is a bigger constraint than network bandwidth, Acronis gives you the option to perform
deduplication on a Storage Node instead of providing deduplication on a Client.
Support for virtual environments
Since Virtual Machines are often very similar to each other, deduplication works well for virtual environments.
Security of deduplicated data
Deduplicated data on Acronis Storage Node could be encrypted using storage industry standard 128-bit, 192-bit and 256-bit AES
encryption.
Manageability
Deduplication can be performed on a Client or on a Storage Node with just a few clicks. Backup policies don’t have to be changed
because Acronis Backup & Recovery 10 Deduplication works for full, incremental and differential backups.
Acronis deduplication option is available for the Acronis advanced edition products*:
