To migrate data, import your backup files to OBS, and DCS will read data from OBS and migrate the data to the target DCS Redis instance. Alternatively, you can import the backup files directly to the DCS instance.
The backup data is stored in Huawei Cloud OBS buckets and removed upon deletion of the corresponding instance. Use cross-AZ replication for data DR. A master/standby or cluster DCS instance can be deployed within an AZ or across multiple AZs for HA.
Create an OBS bucket in the account and region where the target Redis instance is located. If a qualified OBS bucket is available, you do not need to create one. When creating an OBS bucket, pay attention to the configuration of the following parameters.
Solution: Check whether the network between the data plane and OBS is normal. Collect errors and contact customer service. Online migration failed. Send the error information to customer service. Failed to bind the port to the ECS.
2.0 Supported Backup and Restoration Data in DCS instances can be backed up to Object Storage Service (OBS).
Create an OBS bucket on the OBS console. When creating an OBS bucket, pay attention to the configuration of the following parameters. For details on how to set other parameters, see Creating a Bucket in OBS User Guide.
To migrate data, import your backup files to OBS, and DCS will read data from OBS and migrate the data to the target DCS Redis instance. Online migration is suitable when the source Redis instance supports the SYNC and PSYNC commands.
Create an OBS bucket on the OBS console. When creating an OBS bucket, pay attention to the configuration of the following parameters. For details on how to set other parameters, see Creating a Bucket in OBS User Guide.
Due to data caching, a policy involving OBS actions will take effect five minutes after it is attached to a user, user group, or project.
The backup data is stored in OBS buckets and removed upon deletion of the corresponding instance. Data Replication A master/standby or cluster DCS instances can be deployed within an AZ or across multiple AZs for HA.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), and Object Storage Service (OBS), are shared within the same region. AZs in the same region can communicate with each other over an intranet, but AZs in different regions cannot.
OBS OBS provides secure, cost-effective storage service using objects as storage units. With OBS, you can store and manage the lifecycle of massive amounts of data. You can store DCS instance backup files in OBS.
