SYMPTOMS
- backup was taken of a Windows Server 2012 volume with de-duplication enabled
- folder, disk, or volume backup was successfully verified
- when performing a file/folder based restore, data within some files appears to be corrupt (for example, opening a Word document displays strange characters instead of the original content)
CAUSE
Acronis does not support file-level backup and file recovery, including file recovery from a disk backup, of de-duplication enabled volumes - http://www.acronis.com/en-gb/support/documentation/ABR11.5/#23538.html
Further information about Server 2012 de-duplication can be found here - http://technet.microsoft.com/en-us/library/hh831602.aspx
SOLUTION
To successfully recover files from de-duplication enabled volumes, it is necessary to the restore the whole disk or volume. Files can be copied from the recovered volume back to the original location using Windows.
