WHITE PAPER
12
But until the advent of Acronis Backup & Recovery Deduplication, it was out of the financial reach of small
organizations, and some large ones; they included expensive proprietary hardware and most products based their
pricing on the volume of deduplicated data. As a result, organizations 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 Optimization 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 organization 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:
1. Eliminate identical blocks of data and save storage space and cost
2. Enjoy the speed, reliability and random access nature of disk
3. Support much more concurrent backup and recovery jobs
4. Support much longer retention periods on disk, typically 3-6 months
5. Minimize 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.
