Application Scenarios

Application Scenarios

CSDR protects data of both production and DR data centers, providing optimized data security and correctness and ensuring service continuity. CSDR is applicable to the following scenarios:

Production center failure due to a disaster

Production center failure due to a disaster (such as power failure, fire, or natural disaster): DR administrators can perform fault recovery for production ECSs protected by CSDR and quickly start the ECSs in the DR center to recover services, see Figure 22-2.

Figure 22-2 Production center failure due to a disaster

Prevention of potential risks

Prevention of potential risks (such as typhoon and flood): DR administrators can perform planned migration of CSDR-protected production ECSs from the production center to the DR center, and start the ECSs in the DR center quickly to ensure zero data loss. After the risks are eliminated and the production center recovers, the DR administrators can perform reverse reprotection for the protected ECSs and migrate data back to the original production center at the right time, see Figure 22-3.

Figure 22-3 Prevention of potential risks

Planned shutdown

Planned shutdown (due to planned power outage, routine maintenance, or other reasons): DR administrators can perform planned migration of CSDR-protected ECSs from the production center to the DR center, and start the ECSs in the DR center quickly to ensure zero data loss. After the planned migration is complete, the DR administrators can perform reverse reprotection for the protected ECSs and migrate data back to the original production center at the right time, see Figure 22-4.
