Data encryption performance hit and impact for non dedupe hardware ?

[albertwt]

Hi All,

Using the Veeam Backup data encryption with the ordinary NAS as the Backup Repository, I wonder if there is any significant impact in terms of backup performance or restore performance.

Because according to https://helpcenter.veeam.com/docs/backu ... ml?ver=110 the Storage appliance with Deduplication capability will be impacted.

Many thanks for considering my question.

The target repository I am using is connected via iSCSI and the NAS is on RAID 6 (https://www.qnap.com/en-au/product/ts-ec1280u).

Hello,
dedupe appliances are always slow and encryption has negative impact on deduplication. Not really on performance.

Encryption is a CPU task. Storage is irrelevant. With modern CPUs, the impact should be small.

Best regards,

That is great to know, many thanks for the confirmation @Hannes.
