Hanzo Hold was built within the philosophy that less is more when it comes to your data. So, Hanzo Hold only preserves data that you need to preserve (whether on legal hold, or specified in a point in time preservation).
To do that, we never make full copies of your Slack data or preserve anything that's not in scope. We simply outline your data to reveal the custodians and channels in a searchable format. Think of it as a blueprint or map that simply shows you where things are. We only preserve the actual data in Hanzo Hold on your orders.
When Hanzo Hold does preserve data, it pulls data from the Slack Discovery API which is available to Slack Enterprise Grid customers.
