We have configured in AWS, RDS snapshot backups.  We need a way to get the Snapshot copied to our s3 bucket.

What is the best way to perform this task automatically?  a Best Practice or White Paper would be great.

 

Thanks

Hi @ChuckC,

Here is a document that might help.

Thanks,

Only method currently available is a streaming backup using native export tooling as shared by @Gil S. I know engineering is working on a solution that allows you to perform backup copies of RDS snapshots. It is a complicated task, especially because the amount of possibilities they have is limited due to AWS limitations. We raised the request a very long time already and they have been investigating the possible routes, but it might be that AWS is also working on adding functionality similarly to for example EBS-Direct-Read that allows Commvault to perform backup copies without a lot of workaround.

Hello all,

@Onno van den Berg , after 1 year of this thread creation I would like to ask if there is any update.

For RDS backup through Snapshot method, I see that backup copies are still not supported.
https://documentation.commvault.com/11.24/expert/102956_amazon_rds_protection_using_aws_native_snapshots.html

 

So, I guess that the only way to achieve an additional copy (except snapshot in AWS perimeter), is to create a New Snapshot Copy, with source the Primary Snap and destination a S3 bucket for example.

Is that right?

Hi @Nikos.Kyrm 

Indeed as you pointed out already this capability being the ability to create backup copies hasn't arrived, yet. I have no idea what the current planning is, but I do know it is on the roadmap for a very long time already.

Currently there are two ways to create additional copies:

I hope we see the ability to create native backup copies of RDS arrive soon! I hope someone can elaborate on this.

@Onno van den Berg Thanks for your feedback!

Until native backup copies of RDS arrive, if make a Snapshot Copy (with source the Primary Snap and destination a S3 bucket) I think it’s a workaround. Because at the end of the day you will have:
1) snap backup (in AWS perimeter).
2) an addition backup in Disk Library (using Snapshot Copy aux copy).

What do you thing about that?

Best regards,
Nikos

Hi Nikos,

This will make no difference. You can't copy a snapshot backup to a S3 bucket. This proces is called a backup copy and this is not supported, yet. 

So you can continue to protect RDS via snapshots only and create copies of these snapshots to a different AWS account and/or different region, but still in a AWS snapshot format. The alternative is to create native backup which offers the ability to create aux-copies, have the benefit of compression/dedup but which requires direct access to the DB instance and which will have impact on the performance of an instance e.g. looks similar to the backup of a regular DB via an agent.
