You have completed the following operations: Perform a service switchover to the cluster and view the migrated data in the cluster.Then, restore data from the snapshot to the Alibaba Cloud Elasticsearch cluster. Transfer the final snapshot to the OSS bucket.Create the final snapshot for the Amazon OpenSearch Service domain.Stop services that may modify index data.Identify the final snapshot and perform a service switchover.Repeat the preceding steps to restore data from incremental snapshots. Process incremental snapshots on a regular basis.
#Export elasticsearch data to s3 full
Restore data from the full snapshot to the Alibaba Cloud Elasticsearch cluster.Use ossimport to transfer the full snapshot from the S3 bucket to the OSS bucket.Create an Alibaba Cloud Object Storage Service (OSS) bucket, and register it with the snapshot repository of the Alibaba Cloud Elasticsearch cluster.This snapshot is automatically stored in the S3 bucket. Create the first snapshot for the index whose data you want to migrate.
Create a snapshot repository and associate it with an Amazon S3 bucket.To migrate data from an Amazon OpenSearch Service domain to an Alibaba Cloud Elasticsearch cluster, perform the following steps: Data in a snapshot created in an Elasticsearch 1.x cluster can be restored to an Elasticsearch 2.x cluster.Data in a snapshot created in an Elasticsearch 2.x cluster can be restored to an Elasticsearch 5.x cluster.Data in a snapshot created in an Elasticsearch 5.x cluster can be restored to an Elasticsearch 6.x cluster.However, the data can be restored only to Elasticsearch clusters of specific versions: The snapshots can be used to restore data. Snapshot and restore: You can store snapshots of individual indexes or an entire cluster in a remote repository like a shared file system, such as Amazon Simple Storage Service (Amazon S3) or HDFS.Based on open source Elasticsearch, Alibaba Cloud Elasticsearch provides enterprise-class access control, security monitoring and alerting, and automatic reporting. Alibaba Cloud Elasticsearch: It is designed based on open source Elasticsearch for scenarios such as data analytics and searches.You can use Amazon OpenSearch Service to easily deploy, protect, manage, and scale Elasticsearch clusters for scenarios such as log analytics, full-text search, and application monitoring. This service also provides the availability, scalability, and security that are required for production workloads.
Amazon OpenSearch Service is a managed service that offers easy-to-use Elasticsearch APIs and real-time analytics capabilities.
