Is it possible to create a group or user that can read all workspaces, also newly created workspaces.

I know you can add existing workspaces to a group or user but I want to create a group/user that can automatically read (not write) workspaces when there created. No human intervention. 

I want to backup workspaces and sometimes I forget to add new workspaces to the backup user.

Thanks,

how are you backing up workspaces? Ideally, you would use UNC mounts for nexis workspaces (if on windows) and your backup software or script would be able to enumerate all the paths under the nexis system director name. ex: \\nexis-system\share where your backup process would look at the path like \\nexis-system\*
