Redirected restores of SIS (Single Instance Storage) enabled files renders the files as corrupt. The error message below is an example of the message that is seen when attempting to open a .pdf file following a redirected restore.

Restores back to the original location are not affected by this issue.


Adobe Reader could not open 'filename' because it is either not a supported file type or beause the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

This is a major issue for me. I do not have the ability to restore back to the original location. This is archive data and the original location has been removed.

Why is this rated as Severity: Non-data threatening ? 

I have 40gb of PDF files that I cannot restore. Symantec scores again...
