Hello there,

Thank you for raising this issue with us.

Could you confirm with me that you are not currently on the H2 embedded database on Confluence?  If you are, then I would recommend that you first migrate to a supported database per my instructions on this thread: backupEntities Couldn't backup database data

If you are already on a supported database, please tell me if you do a partial XML export of the space instead of a full export, does it complete successfully?

Regards,

Shannon
