Yes, this should be on by default and you can read more about this here: Asset Bank Duplicate Detection.
If you are hosted in our Cloud then please contact support if you have questions about this.
To setup Asset Bank to warn you when you upload a potentially duplicate asset to your system update the duplicate-file-check-on-upload setting to true in your ApplicationSettings.properties file and set "duplicate-asset-check-type" to data or perceptual and restart your Asset Bank.
The duplicate asset warning will be present on both single and bulk upload.
- Single Upload: If you upload an asset via the single upload page Asset Bank will check the existing assets for any potential duplicates. If any are found a page will be displayed prior to entering metadata that shows the potential duplicates and offers the user the option of either continuing with the current upload (and marking the potential duplicates and the new upload as 'non duplicates) or cancelling the current upload.
- Bulk Upload: After performing a bulk upload the system will check for any potential duplicates of any of the assets that were uploaded. If found then a new warning will be displayed on the bulk upload success page that explains that potential duplicates were found and gives a link to resolve the duplicates. Following this link will take the user to a page that lists the uploaded assets and any potential duplicates and for each asset offers the user the option of either deleting the uploaded asset or marking it (and the duplicate assets found) as 'non duplicates'. For any uploaded assets that were deleted the system will provide bulk and batch update links (again on the bulk upload success page) to enable the user to change the metadata associated with the duplicate assets if required.
