How you're replicating your backups to cloud Space Reduction Ratios and Percentages. This concerns me mostly due to the need to replicate my backups to the cloud on an nightly basis and bandwidth vs these file sizes will be an issue. Since the systems are backed up to a remote location, the WAN connection can be relatively slow As a rule of thump you can use 50% data reduction ration (compression + deduplication), since typically you won't see ratios less than that. What backup rates are you currently seeing? Let us know how your testing ends up, happy to help furtherĭeduplication ratio = 50% + (100% - 50%) / 40 = 51.25% The approximate storage and network traffic savings is 48.75 percent (100% - 51.25%), which means deduplication cut these requirements almost in half. So far, 128KB has been the better choice based on what we have seen in the field. Using 32KB segment sizes can improve the dedupe ratio, but at a cost to backup throughput.

Each Backup Exec Agent for Windows Systems has the built-in capability to do client deduplication, and many of the Application Agents ( Backup Exec Agent for Exchange, Backup Exec Agent for SQL Server, etc.) can.

Files that have identical hashes to files already in the target device are not sent, the target device just creates appropriate internal links to reference the duplicated data White Paper: Backup Exec 2010: Deduplication Option Backup Exec 2010: Deduplication Option but a good baseline is that 9:1 ratio.

This is the process where the deduplication hash calculations are initially created on the source (client) machines. Data is not stored again when a backup encounters a segment that is already stored in the deduplication storage folder Client backup deduplication. How Backup Exec Deduplication Works: Deduplication works by dividing data into 128K segments and then storing the segments in a deduplication storage folder, along with a database that tracks the segments. Actual deduplication ratios will vary depending upon data types, retention, and compressibility of your data. Provides application-aware replication with NetBackup and Backup Exec OST interface.
#Upgrade backup exec 16 to 20 how to
Professor Robert McMillen shows you how to setup Deduplication in Backup Exec 20 and 2 CLI support scripting/scheduling. Specify the Server Name for the Remote Agent that is being configured and select Ok

Right click on the media server node in question and select the Add Remote Agent for Deduplication menu item. The Deduplication Option supports integrated deduplication at the Backup Exec media server and on remote computers that have the Remote Agent for Windows Systems installed The effectiveness of data deduplication is often expressed as a deduplication or reduction ratio, denoting the ratio of protected capacity to the actual physical capacity stored Go to the Devices tab (Backup Exec 2010) / Storage tab (Backup Exec 2012 and newer) in Backup Exec console. So, in this case 1289 - 22 / 1289 = 98.3% About the Deduplication Option The Backup Exec Deduplication Option supports a data-reduction strategy by optimizing storage and network bandwidth. Not the third backup of 4 The amount of data that was sent to the CR = Content Router = Backup Exec Deduplication Engine (E) dedup: 98.3% (B) - (D) / (B).

The first backup to that dedupe storage location should be along the lines of the 1.0:1 ratio.
