Hello, everyone!

Join the Community Learning week IT class! learning post

IT class learning time of this phase: September 6th – September 11th.

Answer time of this class: September 6th, 8 AM - September 7th, 4 PM (UTC+0).

Class topic

Post 1. What is backup server?

The FusionSphere virtualization suite offers the following DR plans: metropolitan active-active DR, array-based replication DR, and two-site and three-center DR. It also offers the VM backup and user data backup plans. Customers can choose these plans based on service requirement…(More)

Post 2. Solution Description Cloud Server Backup Service (CSBS)

Cloud Server Backup Service (CSBS) offers the backup protection service for Elastic Cloud Servers (ECSs). It works based on the consistent snapshot technology for Elastic Volume Service (EVS) disks. With CSBS, you can use backup data to restore ECS data.CSBS enhances data integrity and service continuity…(More)

Post 3. Cloud Server Backup Service on HCS

Cloud Server Backup Service (CSBS) enables you to create a backup for your ECS or BMS (including its flavor, system disks, and data disks) and restore service data of the ECS or BMS using the backup data, guaranteeing data security and consistency…(More)

Post 4. Solution Description Volume Backup Service (VBS)

VBS secures your data. For example, if an EVS disk is faulty or a logical error (for example, mis-deletion, hacker attacks, and virus infection) occurs in EVS disk data, you can use data backups to restore data quickly…(More)

Post 5. What are the differences between EVS snapshot and VBS?

EVS disk snapshot is an important data recovery method that records the status of EVS disk data at a specific point in time. The snapshot created for an EVS disk at a certain point in time is independent from the life cycle of the EVS disk. The snapshot can be used to roll back and restore data of the EVS disk at the time when the snapshot was taken…(More)

Class Q&As

After attending this class, please answer all the following questions and submit. Once submitted, the answer cannot be modified.


Click to learn: >>>  next class - Servers

    *1. VBS does not support periodic backup and needs to be manually backed up. (Single choice)

  • A. True
  • B. False

    *2. CSDR uses synchronous replication to fast recover ECSs in the same-city DR center, ensuring zero data loss. (Single choice)

  • A. True
  • B. False

    *3. Which of the following is not a VBS function? (Single choice)

  • A. Backup data management;
  • B. EVS disk data restoration using backups or replicas;
  • C. EVS disk creation using backups or replicas;
  • D. Data backups and backup copies can’t use VBS to create EVS disks.

    *4. Which of the following statements about Huawei backup service are correct? (Multiple choices)

  • A. Volume Backup Service (VBS) enables the system to create EVS disk backups. The backups can be used to restore EVS disks, maximizing user data accuracy and security and ensuring service security.
  • B. CSDR provides remote disaster recovery protection for ECSs. If the production center fails in a disaster, the protected ECSs can be restored in the remote DR center.
  • C. VHA service provides local storage-based active-active protection for EVS disks on ECSs.
  • D. CSBS executes a full backup for an ECS that has not been backed up using CSBS, and performs incremental backups subsequently.

    *5. Which of the following statements about VHA are correct? (Multiple choices)

  • A. Production storage: Storage device used to store service data OceanStor V3, OceanStor V5, OceanStor Dorado V3, and OceanStor Dorado V6 are supported.
  • B. DRExtend: Creates a HyperMetro pair and a HyperMetro consistency group for the active and standby volumes, and adds the pair to the HyperMetro consistency group.
  • C. DR rules: The rules are deployed on computing nodes. One DR rule is configured for one set of storage array.
  • D. VHA Console: Provides the VHA service console. Provides the VHA service console.
