# What's Cooking in Business Central: Storing Document Attachments outside the Database

> Offloading Business Central document attachments to external storage (blob storage, file share, SharePoint): setup with external file accounts and file scenarios, upload and delete policies, nightly job queue, and the backup risk the customer takes on.

[Watch on YouTube](https://www.youtube.com/watch?v=6sH2u4jt-ow) · Microsoft Dynamics 365 Business Central (YouTube) · 2025-11-27 · 4:39 · tier official · reviewed (checked by Opus)

## Overview

The video walks through storing document attachments outside the Business Central database. It starts with setting up an external file account, then assigns it to the Document Attachments External Storage scenario, enables the feature and sets the required root folder.

It then covers upload and delete policies: a job queue that runs at 1:00 a.m. by default, immediate delete after upload, delayed delete with a date formula (7 days in the example), and whether external files are deleted when an attachment is removed in Business Central. An upload is demoed and checked in Business Central. The video closes with the storage sync feature for existing attachments and restoring attachments back from external storage. It warns that the feature is used at the customer's own risk, because backups of offloaded files become the customer's responsibility.

## Key points

- Setup uses the External File Accounts and File Scenarios pages, with the Document Attachments External Storage scenario assigned through Assign Scenarios.
- After enabling the feature in External Storage Setup (via Additional Scenario Setup), it is important to set a root folder for the storage.
- Scheduled upload should be enabled; it creates a job queue that runs each night at 1:00 a.m. by default to offload document attachments.
- Immediate delete after upload conflicts with delayed delete: enabling immediate delete makes the delayed delete option non-editable.
- Delayed delete keeps files in Business Central for a period set by a date formula; the example shows 7 days.
- An option controls whether external files are deleted when attachments are deleted, covering scenarios where you delete a file in Business Central but keep it on external storage.
- Uploaded attachments can be verified from the Document Attachments action in Additional Scenario Setup, where Uploaded to External is set to true.
