DD Boost compressed restore improves backup read performance by using data compression techniques. This option enables DD Boost compressed restore to improve DD Boost backup read performance. Compression reduces restore times but increases CPU usage on both systems.

Restore VM sessions data is compressed on the PowerProtect DD series appliance before transmission to VM Direct Engine where it is uncompressed. This functionality results in reduced network load that provides up to 50 percent reduction (based on in-house testing) in restore times for bandwidth-limited setups.

Data Manager provides an option to enable the DD Boost compressed restore from the Data Manager UI and from restore VM sessions API for VM Direct Engine.

The following screen shows the option to Enable DD Boost Compression from Data Manager UI during restore:

The following screen shows the option to Enable DD Boost Compression from restore VM sessions API for VM Direct Engine:

When set to false, the application agent does not enable DD Boost compressed restore. When set to true, the application agent enables DD Boost compressed restore.

This option can be controlled by using the API enableCompressedRestore property in a POST /api/v2/restored-copies API operation.

For more information, see the recovery and reuse management section of the PowerProtect Data Manager REST API documentation.

DD Boost compressed restore applies to the following use cases:

• Direct restore to ESXi
• Create and restore to new virtual machine
• Restore to original folder and overwrite original files
• Restore individual disk

Note: DD Boost compressed restore does not apply to NFS-based restore (Instant restore).
