Follow the steps provided to create a replica (a file geodatabase) from the REST endpoint of the service to save attachments from a hosted feature service.

Log in to the ArcGIS Online organizational account.
Navigate to My Content, and browse to the desired feature service with attachments.
Select Show Item Details. The item details page for the hosted feature service displays.
Scroll down to find the Layers section. Click the small arrow icon next to the layer with the attachment to be retrieved, and click Service URL.
Remove the Layer ID from the end of the service URL.
Scroll down to the bottom of the page, and click Create Replica.
Specify the 'Replica Name'. The name cannot contain any spaces.
Specify 'Layers' with a value of 0.
Set the following options accordingly based on the size of datasets. For small datasets: a. Return Attachments: True b. Sync Model: none c. Data Format: FILEGDB
Click the Create Replica button. A 'statusURL' displays at the bottom of the screen. Click the URL.
In the new page, click the Result URL. The zip file is downloaded.
To get the output, extract the file geodatabase. This contains the features and attachments from the hosted feature service.
