It is a good practice to perform backups of your OpenSearch (OS) data to another storage service. This way you can access your data and restore it if something unexpected happens to it.
In this article, you can find out how to dump your OpenSearch data to
an:
- AWS S3 bucket
To copy the index data, we will be using elasticsearch-dump
tool. You can read the instructions on GitHub on how to install it. From this library, we will use elasticdump command to copy the input index data to a specific output.
Make sure to have elasticsearch-dump tool installed for the next steps.
Copying data from OpenSearch to AWS S3
Prerequisites
- OpenSearch cluster as the
input - AWS S3 bucket as the
output
Information about your OS cluster and AWS service:
OpenSearch:
-
SERVICE_URI: OpenSearch service URI. -
INPUT_INDEX_NAME: the index that you aim to copy from your input source.
S3 bucket:
- AWS credentials (
ACCESS_KEY_IDandSECRET_ACCESS_KEY). - S3 file path. for e.g.
s3://${BUCKET_NAME}/${FILE_NAME}.json
Find more information about AWS credentials in the AWS docs.
Export OpenSearch index data to S3
Use elasticsearch-dump command to copy the data from your OpenSearch cluster to your AWS S3 bucket. Use your
OpenSearch SERVICE_URI for the input. For the output, choose an AWS S3 file path including the file name that you want for your document.
{.shell}
elasticdump \
--s3AccessKeyId "${ACCESS_KEY_ID}" \
--s3SecretAccessKey "${SECRET_ACCESS_KEY}" \
--input=SERVICE_URI/INPUT_INDEX_NAME --output "s3://${BUCKET_NAME}/${FILE_NAME}.json"
That is how you can copy your OpenSearch data to a S3 bucket. 🙋🏻♀️
