IT38652: BACKUP OF MICROSOFT ONEDRIVE FILES MARKED AS 'ON DEMAND' FAILS WITH ANS4004E IF VSS SNAPSHOT IS USED

APAR status

• Closed as Permanent restriction.

Error description

• If the option "SNAPSHOTPROVIDERFS VSS" is used in the dsm.opt,
  then the backup of a OneDrive file which is marked as 'On
  Demand' will fail with the following error message:
  
   ANS4004E Error processing 'x:\path\filename': destination file
  or directory is write locked
  
  An 'On Demand' file is stored in the cloud, and is automatically
  retrieved by OneDrive when being accessed.
  
  The issue is being seen because during the backup with VSS
  active, the file is retrieved to the VSS snapshot and not to
  it's original location, but a volume shadow copy is read only
  and the OneDrive file cannot be retrieved here.
  
  
  IBM Spectrum Protect Versions Affected:
    Clients V7.1 and V8.1 on Windows platforms
  
  
  Additional Keywords: TS003850631 197352  On-Demand TSM
  

Local fix

•  Use client option "SNAPSHOTPROVIDERFS NONE" .

Problem conclusion

• If SNAPSHOTPROVIDERFS VSS (by default since 8.1.8.0) is used,
  the backup of OneDrive file marked as 'On Demand' will fail with
  the error message ANS4004E. The reason is that a volume shadow
  copy is read only.
  This behavior works as designed.
