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?

Before deploying Huawei ' s active-active solution, the customer ' s current multi-selection network information that needs to be collected includes: (multiple selection)

(multiple choice) Which of the following is correct in IDC ' s description of the characteristics of big data?

A company purchased a set of Huawei horizontally extended file storage to build a file sharing system. Current ministries

The clients of the door use different IP subnets, and the storage administrator configures the front-end service IP addresses of all nodes to belong to the same subnet. storage

Which steps are correct for the administrator to configure the subnet ()

In the following options, the description of the bucket (Bucket) is incorrect.

The application scenarios of Huawei Oceanstor 9000InfoReplicator feature include: (multiple choice)

After Huawei Distributed Storage enables the object deduplication function, the system will automatically find duplicate objects globally.

And only keep one copy of the same object and delete the redundant duplicate data. The original duplicate data is replaced with a single copy that points to the reservation.

A copy of the reference.

InfoReplicator supports splitting the Pair, that is, temporarily suspending the data between the master and slave directories

Synchronize. If the user wants to restore the data synchronization of the Pair and re-maintain the same data in the master and slave directories, they only need to create a new one manually.

Pair is OK

The disadvantage of physical tape libraries is that the hardware and mechanical failure rate is relatively high, and the single-selection tape media itself is relatively fragile and vulnerable to external environments.

Environment (temperature, humidity, dust, etc.), it is prone to failure.

What is wrong about the concept description of object storage service (compatible with OpenStack Swift interface) among the following options:

(Single choice) Huawei OceanStor 9000 FRU replacement tool maintenance does not support which of the following modules or devices can be replaced?

Single-select a Huawei Oceanstor 9000 cluster site, configure 4 P36 nodes, and use the back-end IB networking, regardless of temporary conditions.

In this case, how many back-end storage network IP addresses should be planned?

Back-to-back mode, answer mode, which completes the coding and decoding work in the FCoE protocol, is the following single-choice layer

Second-rate.

Single selection Huawei’s converged storage has the function of parallel and fast data reconstruction. Data fragments are scattered in the resource pool. After a hard disk fails, the Automatic and parallel reconstruction within the entire resource pool, only the actual data is reconstructed, and no separate hot spare disk is required.

Huawei hybrid flash storage system controller subrack and disk subrack are interconnected by mini SAS interface, the highest transmission rate

Up to 8GB/s.
