FSAUTILITY restore all files and replace placeholders

Have you tried:

FSAUTILITY -t -s \\source\share -d \\dest\share

You will need to check SQL to determine what the VolumeEntryId is for that volume.  If you added a folder target and choose to create an Archive Point then that would possibly create a duplicate archive.  

USE EnterpriseVaultDirectory

SELECT * from FileServerVolumeEntry 

WHERE VolumeName = 'DOKAEP' 

From this you can then obtain the VolumeEntryId for the DOKAEP volume. With this number you can perform another query. 

USE EnterpriseVaultDirectory

SELECT * from FileServerVolumeArchiveEntry 

WHERE VolumeEntryId = 'Number_from_first_query'

This may not return any rows, which would seem to be the indication from the error.  If so, then the volume will need to be associated with the archive.   I would suggest opening a Support case so that they can walk you through the correct process.
