AWS Backup - using tags - transitioning and lifecycle help

I'm not sure If I did understand your questions but what I understood was that you're looking for a lifecycle management option for your backups performed by AWS backups that get processed daily/monthly.

AWS has recently added a new feature in AWS backup (Advanced features) for Amazon DynamoDB backups.

To know more about Advanced DynamoDB backup:

Copying tags onto backups

I hope it fulfills your requirement.

Hi,

As noted above, we have added support for DynamoDB for lifecycle transition to cold storage. We also have enhanced tag based selection, where you can select only DDB service & only tables with a specific tags. You can create tag based filters with boolean expressions.

In the backup plan ensure you have the the rules for the daily/weekly/monthly, and in the life cycle rule, ensure to point to AWS backup, when you want it to move blocks to Cold storage.

Keep in mind though, that blocks that are needed for your warm backups from the golden image of the table, will remain in hot, to enable you to restore that PITR.

Hope this helps
