or scheduling the 'Activate Automatic Log Backup' action in DB13:

        19-03-2016 17-13-55.png

 
it fails with the below errors:

         -24988,ERR_SQL: SQL error

           -126,Databackup missing (Backuphistory lost)

           20008,(AUTO)SAVE LOG has been aborted due to missing backup history

 The errors can also be seen in the Database Manager Log File('dbm.prt'):

LOG backups (no matter Automatic or Manual) can only be made once at least one COMPLETE DATA Backup was generated, thus initializing the backup history of the databae. However, even after creating a COMPLETE DATA Backup, the automatic LOG backup activation fails with the above error.
