AWS Open search backfill mechanism

Question

We have a use case in which we have to delete data from some indexes, within a specific time range. We are using a delete-post request which has time range and indexes on which deletion is performed. I wanna know if in case the wanted data gets deleted. Is there any support given by aws, to backfill our data back?

Answer

Hi,

If you want to recover data that has been deleted in Amazon OpenSearch Cluster, following are the available options:

1) Automated snapshots that are available for your cluster. At any time, automated snapshots of the last 14 days will be available[1].

2) Any manual snapshots that you have taken yourself.

These snapshots can be used for cluster data recovery. However, it's crucial to ensure that the snapshots cover the specific time range of the data you want to recover.

Therefore, it's recommended to carefully manage and schedule your manual snapshots to align with your deletion strategy, ensuring that you have the ability to restore any wanted data that might be accidentally deleted.

Answer

AWS does not have access to data you add or remove from the services. Please refer the following link for AWS shared responsibility model.
