Okay. Should we add something to the documentation then, along the lines
of:

"Keys generated between a backup being made and the backup done command
being run will be erroneously marked as having been backed up. To avoid
this either choose a backup schedule that doesn't run while the enforcer
might be generating keys or shutdown the enforcer while a backup is
performed".
