When compliance mode is enabled on a bucket, the local source corresponding to the bucket is set to WORM (write only read many) mode. WORM mode prevents the files in the local folder from being edited and deleted. If a local file has been modified, the system will force the user to save the content as a new file. To enable compliance mode, follow the steps below.
Any modifications made to versioning and compliance settings now sync between the WCN software and the WCN storage account (Wasabi console). To ensure that updates take effect in the WCN software, users are required to refresh the WCN software by clicking Refresh all following any modifications made in the Wasabi console.
