Hi, you can use Shift start from version 24.1 to duplicate your workspace 

I totally agree with Rom01 , since the copy is at a single entity level & export/import will miss certain key attributes, like History, comments, attachments, linked entities/relations. why the octane is missing one of its core feature to perform, which the restore of workspace with out deleting the original, & clone a workspace in the same space/other isolated space. it is restricting the lot of ongoing opportunities in the current different organizational way of data handling. iulia_andreicut  Please have this implemented. i don't see a downside of this functionality but rather not implementing it.

iulia_andreicut The solution you describe is only a solution for tests, which can be copied only between workspaces of the same shared space. And the export/import of the entities unfortunately does not take into account attachments and comments. But the attachments and comments are also important parts of the items.
We need a solution for all possible Item-Types (Epic, Features, Backlog-Items, Tests, ...) including all fields (also comments and attachments) also for copying between workspaces of different shared spaces.

Hi Rom01 ,

The Backup and Restore of a workspace functionality will not be delivered in 16.1.200.

Still, it's scope is to restore a corrupted workspace, so during the restauration, the original workspace will be deleted.

In the use case described by you, the copy/move tests and user stories between workspaces of the same shared spaces can help, or the export/import of the entities to excel.

Kind Regards,

Iulia
