For Huawei's intelligent distributed storage products, clusters can only provide block storage and object file storage interfaces for upper-layer applications.

Compared with the traditional RAID algorithm, the erasure code redundancy technology adopted by Huawei Ocean9000 has higher reliability and more flexible redundancy strategy. In the erasure code storage mode, the storage system can withstand concurrent failures of N disks at most.

A customer's existing production environment server performance is relatively high, production network resources are relatively tight, and no snapshot license has been purchased for the generated storage. At present, the customer wants to introduce the backup service. Under the existing configuration, which backup networking method is recommended for the user?

A user deploys a backup system for the database business, the production volume capacity is 2TB, and the incremental data change is 20GB/day, which is retained for 1 month, and routine mount tests are performed quarterly.
When doing back-end capacity planning, if using advanced backup, which of the following options is close to the back-end capacity requirements?

If the Oracle business in the HyperMetro solution has multiple data LUNs and multiple log LUNs, it is recommended to add the active-active pair constructed from the data LUN to one consistency group and add the active-active pair constructed from the log LUN to another consistency group, to ensure data consistency.
