Hello,
One of the Client Computers just wont do the backup 
I get following error
Error while getting files in folder “\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy8\MMI\JobLog\20140927-110350\JobSicherung”. Windows errorcode: 87. Access to root directory is gone too. Shadow copy was probably deleted while indexing.
Constructing of filelist of “SortJet-PC” failed: error - index error
Backup had errors. Deleting partial backup.
I tried again to backup error again, but at another spot
Error while getting files in folder “\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy9\MMI\Antriebsdaten\SEW\207_80U02_Rieme2”. Windows errorcode: 87. Access to root directory is gone too. Shadow copy was probably deleted while indexing.
Thank you
