APAR status
Closed as program error.
Error description
Restored files that were backed up from a Windows 2012 deduplicated volume might be inaccessible. A typical message is The file or directory is corrupted and unreadable The problem occurs because the deduplication reparse point is restored along with the rest of the file data. In this case, if the data is restored to a non-deduplicated disk, or Windows deduplication is otherwise unable to utilize the reparse point, the file will appear to be corrupted or unreadable. This is a problem with restore, not backup. The backed up data is otherwise intact. Note: This is Windows 2012 deduplication. Not Tivoli Storage Manager deduplication. Initial impact: Medium Platforms Affected: Windows 2012 Additional Keywords: TSM 0x80070570
Local fix
Use the Microsoft Windows utility fsutil.exe to remove the reparse point from the affected files: fsutil reparsepoint delete <filename> where <filename> is the name of the affected file. Use double quotation marks around the file name if the file name contains blank spaces. Examples: fsutil reparsepoint delete e:\data\income2013.txt fsutil reparsepoint delete "e:\data\billable hours.csv" If fsutil.exe returns an "access denied" error, boot the system into "Safe Mode", then try the fsutil.exe command again.
