Airtable base backups to S3

This workflow exports every table in a base as its own CSV, saves the files in a time-stamped folder in Amazon S3, pings you on Slack, and optionally prunes older copies. You get an automated weekly backup that is easy to inspect or re-import as needed. You can easily swap the S3 node for the storage provider of your choice.

++How it works++

Weekly Backup - Schedule trigger fires weekly - Sets and formats the week ex. [2025-W12] - Create a folder in S3 bucket with the week - Loops through all tables in Airtable base creating CSVs and uploading to the new path - Slack message is sent on completion

Monthly Prune - Schedule trigger fires weekly - Sets a cut-off date 4 weeks in the past - Lists folders in S3 - Deletes all folders > 4 weeks old

++Setup Steps++

1. Clone workflow 2. Swap credentials for Airtable, AWS, and Slack - Ensure AWS credential has appropriate IAM policy to manage bucket & objects 3. Set workflow to "Active"
