Offloading data compression during restores to a data processing unit in a deduplication backup system

A computer-implemented method of optimizing client-side inline deduplication of backup data in a backup client, comprising:

• performing the inline deduplication by filtering streaming data as it is received by the backup client for a backup process executed through a backup server;
• deploying a data processing unit (DPU) functionally coupled to the CPU to perform at least some of the inline deduplication performed by the CPU;
• compressing, during a restore process from the backup server to the backup client, data read by the client after decompression;
• and
• performing, in the DPU, at least some of the decompression.

A computer-implemented method of optimizing client-side inline deduplication of backup data and decompression of restored data, comprising:

• deploying a Data Domain (DD) Boost file system (FS) interface (API) to access a DD Boost library on a backup client hosting one or more applications generating the backup data backed up using a deduplication process;
• deploying a data processing unit (DPU) functionally coupled to the CPU to perform at least some of the deduplication process through the DD Boost API;
• receiving, in the backup server, a request to restore the backup data to the backup client;
• compressing the backup data prior to transmission to the backup client;
• and
• decompressing the transmitted backup data restored to the backup client, wherein at least part of the decompressing is offloaded by the backup client to the DPU.
