Enabling client-side deduplication capabilities

Client-side deduplication or Client Direct is an easy way to improve the performance of your backups to an MSDP target. Backup performance can be improved by using the OpenStorage storage server instead of the media server to transfer the data during backups. For more information on Client Direct, see NetBackup Deduplication Guide.

This can be done by adding the OST_CLIENT_DIRECT new entry in the /usr/openv/netbackup/bp.conf file of the media server. The OST_CLIENT_DIRECT entry can have one of the following values:

  • 0 - Client Direct will not be used as the data transfer method to transfer the data to the specified host.

  • 1 - Client Direct will be preferred as the data transfer method to transfer the data to the specified host, contingent on Client Direct capability probes on the storage server permitting the same. This is the default value set for Cloud Scale deployment.

  • 2 - Client Direct will always be used as the data transfer method to transfer the data to the specified host.

To change the value of OST_CLIENT_DIRECT entry through the bpclient CLI, refer to the NetBackup Commands Reference Guide.

To enable client-side deduplication during restores, add OST_CLIENT_DIRECT_RESTORE [=0/1/2] entry to the bp.conf file of the media server(s). A new entry OLD_VNETD_CALLBACK=YES must be added to the bp.conf file of all the clients that would use the client-side dedupliction feature during restores, barring which restore jobs would fail. For more information, see NetBackup Administrator's Guide, Volume I.

The restore mode (for enabling/disabling Client Direct) can also be changed using the bpclient CLI as listed under client_direct_restore of the NetBackup Commands Reference Guide.

If Client Direct is enabled/disabled using the bp.conf file and through the bpclient CLI, then the configuration in bpclient would take precedence over the bp.conf file changes.
