Table 1 – Client Deduplication
* Note – for Client deduplication with Backup Exec Agent for VMWare (AVVI) and Hyper-V, the Backup Exec Remote
Agent must be installed in the Guest Operating System. In this circumstance, the Remote Agent is responsible for
performing the backup, and not the Agent for VMWare or the Agent for Hyper-V. Symantec recommends that for
optimal deduplication, a Remote Agent also be installed in Hyper-V guests.
Media Server Deduplication
Media Server deduplication can be a useful and effective deduplication method for Linux and Solaris environments.
This method of deduplication is entirely performed on the PowerVault DL Backup to Disk Appliance and does not
impact source systems any more than a typical backup.
Media Server deduplication is optimal for situations where:
• The remote system’s processor is fully utilized: If the remote system has no processor cycles to spare for
deduplication calculations, Media Server deduplication can take the load and still perform deduplication.
• The remote system is NetWare, Linux, or Solaris: The Remote Agents for non-Windows platforms do not
have the ability to do client deduplication. These systems can only take advantage of Media Server
deduplication to greatly reduce the amount of storage necessary for backups.
Media Server deduplication is NOT recommended for the following environments:
