A . Client-side deduplication only works when there is a Deduplication Cache configured on the server.
B. Client-side deduplication generally eliminates the deduplication workload on the server for that particular client workload.
C. Client-side deduplication only eliminates the deduplication workload on the server for that workload when a Deduplication Cache is configured on the client.

Answer: B

Explanation:

According to the IBM Spectrum Protect documentation1, one statement that is true regarding client-side and server-side deduplication is B. Client-side deduplication generally eliminates the deduplication workload on the server for that particular client workload. This statement means that when client-side deduplication is enabled, the backup-archive client removes redundant data before sending it to the server, which reduces the amount of data that needs to be processed by the server. https://www.ibm.com/docs/en/spectrum-protect/8.1.9?topic=throughput-tuning-client-side-data-deduplication
