The VSA is installed on the virtual machine, and the MA is installed on the physical machine. Scenarios where this kind of backup networking is not applicable:
In the data replication technology used for disaster recovery, the data replication technology at the host layer is compatible with servers and storage devices.
A user plans to deploy an active and standby disaster recovery system. The distance between the active and standby sites is about 1000KM. The RPO is required to be less than 1 minute.
It is recommended to use asynchronous remote replication.

Which one of the following statements about synthetic full backup is wrong? (single choice)
In the Huawei OceanStor backup solution, when configuring the backup software to create a storage strategy, you need to consider which of the following configurations
Module, (multiple choice)
The backup situation of an enterprise application was that on February 1 (Feb 1), a single-selected full backup of all files and directories was performed, and 2
Cumulative incremental backup was performed on February 2 (Feb 2), February 3 (Feb 3), and February 4 (Feb 4).
The service disk fails, and now I want to restore to the February 4th version, what backup files are needed?
In Huawei’s local high-availability solution, if the HyperMirror feature is adopted, which feature must also be used to correct the difference?
The structure stores the entire column to create a mirror.
Which of the following are typical application scenarios of Huawei's active-active disaster recovery solution? (multiple choice)
The storage capacity of site A is 2543GB. The storage capacity of site B is 3000GB. The storage capacity of site B is 3000GB.
The backup data is remotely copied to site A and saved. Consider the case of replication compression, the compression ratio is 3, and the back-end storage capacity required by site A is calculated.
What is the amount?
What are the advantages of parallel data deduplication: (multiple choice)
Which of the following descriptions is correct?
1. The goal of backup is to prevent human misoperation or system problems. It saves historical data and the recovery time is relatively long. 2. Backup
Solutions are usually implemented using snapshot, mirroring or replication technology.
Send a control command through the backup server, first take a snapshot (or other similar operations) of the data volume that needs to be backed up,
Make a copy, then use the backup server to mount the snapshot volume, and use the backup server to back up the data on this volume to the backup
On the device. What type of backup networking is described in the above workflow?
