I am trying to back up my personal space (using space tools Full XML format ) on a Confluence 7.9.3 instance. When I do this, it takes about 2 seconds and then creates an export with zero attachments. If I am in space tools, I see no attachments, but I have content that is showing in the personal space. I seem to have the appropriate levels of permission, and if you look at the space, you see subordinate files in the space...
I am not a full time Confluence admin, but am a long time Linux System administrator.
