Typical cases are user error where someone accidentally deletes an item from a tenant. The image guys have a good structure where images become unavailable and are recoverable for a certain period of time. A regular periodic task cleans up deleted items after
a configurable number of seconds to avoid constant database growth.<br>
<br>
My preference would be to follow this model universally (an archive table is a nice way to do it without disturbing production).<o:p></o:p></p>
