=== Security issue with backups after re-flashing XOs ===

=== Restore backups after re-flashing XOs ===

The usecase:

The usecase:

* the XO wants to restore Journal content from previous backups, but from school server point of view, it is regular registration request from new XO that provide the same serial number that existing registration uses.

* the XO wants to restore Journal content from previous backups, but from school server point of view, it is regular registration request from new XO that provide the same serial number that existing registration uses.

Since this usecase is common for the current XO deployments, sugar-server will process a workaround with permitting such re-registration to let people do restore after re-flashing, even if private key is lost. This will happen only for XO laptops, for the rest case, workflow is [[#UUID_per_Sugar_user|regular]].
