Deduplication

Primary storage in small and large companies alike is growing at 50% - 100% a year. IDC research conducted in the second half of 2008 shows a 3,000% increase in the amount of global digital data created and stored on a worldwide basis over the past three years. Deduplication is a proven way to tackle the data storage issue, eliminating redundant data in a storage system and promising to reduce backup data volume up to 90% or more. Now, administrators can chose to either stretch storage purchases over a much longer period of time or store more data on existing resources.

But until the advent of Acronis Backup & Recovery Deduplication, it was out of the financial reach of small organisations, and some large ones; they included expensive proprietary hardware and most products based their pricing on the volume of deduplicated data. As a result, organisations that could afford it tended to protect only their servers, not their workstations. With introduction of a software-only Acronis Backup & Recovery Duplication option priced on a per machine basis, deduplication is made affordable for small and large companies alike, and its benefits can be applied to workstations as well as servers.

Storage Capacity Optimisation for Backup Images

Data from backup images typically creates the most duplication. In the case of backup for one hundred Windows machines, operating system files of about 2GB in a Windows machines is almost identical, and would be duplicated one hundred times when backup is taken the first time for every server. If the organisation has a policy to retain three full backups for every server, the total amount of storage required for the Windows operating system alone would be around 600GB, in fact only 2GB is unique.

In fact, any duplicated files or blocks that exists within or across these servers, only one copy will exist after deduplication. For user created data such as user home directories, significant duplication of files and bocks may also exist and these duplications will also be eliminated and storage saved.

Using Acronis Backup & Recovery 10 Deduplication in this case has the following benefits:

  • Eliminate identical blocks of data and save storage space and cost
  • Enjoy the speed, reliability and random access nature of disk
  • Support much more concurrent backup and recovery jobs
  • Support much longer retention periods on disk, typically 3-6 months
  • Minimise the need for expensive and unreliable tape library storage devices
  • Network Bandwidth Reduction

Acronis deduplication uniquely allows its user to choose between deduplication at source and at storage. When deduplication at source is selected, the backup client performs the deduplication process before transmitting the data to the storage node, thus saving bandwidth requirement. When deduplication at storage is selected, the backup client transmits all backup data to the storage node and deduplication is done by the storage node, thus saving CPU resource on the backup client.

Deduplication at the source enables remote office backup over WAN links. As backup data is deduplicated before transmission, bandwidth requirement is typically reduced by 80-90%. By enabling deduplication at the source for remote office backups organisations can enjoy the following benefits:

  • Eliminate tape or tape library storages at the remote sites
  • Minimise manual intervention at the remote sites for tape media management
  • Eliminate need to transport backup tapes to central location
  • Eliminate data leakage risks during tape transportation

Acronis Deduplication - Network Bandwith Reduction

Acronis® Backup & Recovery™ 10 Deduplication saves storage costs and network bandwidth

The Acronis® Backup & Recovery™ 10 Deduplication option provides affordable file and block level software deduplication capability for workstations and servers, helping organisations of all sizes maximize use of their storage infrastructure, while saving costs and increasing capacity.

With the Acronis deduplication option, cut data storage requirements by 90% or more, by eliminating replicas of the same file or block on either the source or target. If data already exists on the storage node, then only a link is created to associate the data with the backup client.

The Acronis Backup & Recovery 10 Deduplication module integrates with any Acronis® Backup & Recovery™ 10 Advanced product

Resource and Cost Savings

Acronis Backup & Recovery 10 Deduplication brings storage-efficient backup and recovery to organisations of all sizes. It helps IT administrators save on costs in four ways:

  • Priced per machine, rather than by storage capacity or number of CPUs.
  • Reduces the volume of disk storage needed for backups
  • Increases the number of backups you can save within existing data storage
  • Frees network data transmission bandwidth and optimises data transfer speeds

Top Benefits

  • Lower overall cost of storage. By eliminating redundant data being backed up, store less data and save on storage space and operation cost
  • Allows IT administrators to meet Federal and corporate compliance requirements more efficiently.These requirements can create massive additional amounts of data, and deduplication reduces the cost of maintaining it.
  • Promotes a "greener" IT operations.Deduplicated data is more environmentally efficient because it reduces the amount of electricity consumed and equipment needed to backup IT environments.
  • Fast return on investment.Purchasing Acronis Backup & Recovery 10 Deduplication pays for itself quickly through a combination of reduced:
    • Electrical consumption
    • Server and disk purchases
    • IT facility floor space
    • Administrative overhead
  • Faster recoveries. Tight integration with Acronis Backup & Recovery 10 Advanced Editions reduces recovery times to minutes.

Key Features

  • Multi-type backups. Deduplication can be applied to full, incremental and differential backups.
  • Highly secure. Deduplication data stores need special protection so they cannot be compromised. Acronis stores deduplication components separately, with special safeguards to prevent direct deletions of multi-instance data. You may also encrypt deduplicated data and limit vault access only to those having password access.
  • Uses commodity storage hardware. As a software-only solution, Acronis bypasses the need for costly proprietary hardware.
  • Easy to use. Acronis deduplication functions are carefully designed for simplicity of operation, and we feature page-based navigation to reduce the need for extensive training.
  • Fully integrated with Acronis® Backup & Recovery™ 10 Advanced Editions. By integrating deduplication functionality with protection for servers and workstations, a machine failure won't force IT administrators to carry out a time-consuming rebuild before one can regain access to deduplicated data. Acronis integration enables recoveries of systems in minutes, rather than hours or days. Compare this with deduplication offerings from other vendors whose deduplication products are incompatible with their backup and recovery products: a system failure may make deduplicated files inaccessible for hours, perhaps days.
  • Source or target deduplication. Pick where the deduplication process is done, at either the source or target machine
  • Sensible cost. Some companies price their deduplication products by the amount of data that is deduplicated, making it difficult to gauge the total cost of ownership. Pricing for A Acronis® Backup & Recovery™ 10 Deduplication is per protected machine, bringing this capability to both large and small organisations.
