3.Data Recovery

Failure Confirmation and Data Repair Drive3 implements an enhanced risk classification and confirmation strategy called RAFI (Risk Assessment for Failure Identification) to ensure prompt identification of data failures.

Additionally, various methods such as delayed repair, parallel repair, and optimization of lost data block identification processes are employed based on factors like parallelism, transmission volume, and timing.

These techniques effectively improve repair performance, guaranteeing comprehensive availability of user data.
