Real time sync from FSx ONTAP to s3

Question

Is it possible to implement a real time sync between FSx ONTAP and an s3 bucket?

Hello,

While it's not possible to implement a true real-time sync between FSx for ONTAP and an S3 bucket, there are a few approaches you can take to achieve near real-time synchronization:

AWS DataSync can be used to transfer data between FSx for ONTAP and S3, but it has some limitations:
* The minimum sync frequency is hourly.
* It's not designed for real-time or near real-time synchronization.

Another approach for near real-time sync would be to use AWS Lambda:
* Set up S3 event notifications to trigger a Lambda function whenever files are added or modified in the S3 bucket.
* The Lambda function would then copy the new or modified files to the FSx for ONTAP file system.
* For syncing from FSx for ONTAP to S3, you could potentially use FSx for ONTAP's audit logging capabilities to detect file changes and trigger a Lambda function to copy those changes to S3

Even though still far from a real time sync, this  solution allows for synchronization with latency typically under 3 minutes

I apologize, but there seems to be a misunderstanding in your question. FSx for ONTAP and FSx for Lustre are different file system offerings from AWS, and the information provided in the sources does not cover FSx for ONTAP's integration with S3.

However, I can provide information about real-time synchronization between Amazon FSx for Lustre and Amazon S3, which might be helpful if you're considering file system options that integrate well with S3.

FSx for Lustre offers enhanced integration with Amazon S3, including full bi-directional synchronization. This means that changes made in the FSx for Lustre file system can be automatically exported to the linked S3 bucket, and changes made in the S3 bucket can be automatically imported into the file system. This synchronization includes new, changed, and deleted files.

To set up this real-time sync, you would create a data repository association (DRA) between your FSx for Lustre file system and an S3 bucket. You can configure automatic import and export policies to ensure that changes are propagated in both directions.

It's important to note that while this synchronization is automatic, it may not be instantaneous in the strictest sense of "real-time." The exact timing of the sync would depend on various factors such as the size of the files being transferred and the current system load.

If you specifically need FSx for ONTAP integration with S3, I would recommend checking the latest AWS documentation or contacting AWS support for the most up-to-date information, as the provided sources do not cover this specific scenario.
