Deduplication, Encryption, and Compression

In addition to data deduplication, we can also apply compression and encryption on a data store.

If you enable encryption, the Arcserve UDP Agent (Windows) consumes the CPU resource to encrypt the data. As encryption is applied only to the unique data, the CPU resource needed for encryption could be minimum where the deduplication percentage is high.

• With no compression and deduplication, the CPU usage is less for the compression task and the data stored is in the non-compressed format.
• With standard compression and deduplication, the CPU usage is optimal for the compression task and the data stored is in a compressed format and the requirement for storage space is less.
• With maximum compression and deduplication, CPU usage is maximum for the compression task and the data stored is 2-3% more and the requirement for storage space is less.
