SQL Backup

We are backup SQL server 2008 R2 using  windows server network share. We never had any problem. My our company has installed NAS device. When running SQL backup now we are seeing error message " <%SQLSERVER%> calling non existence file share named filestream.hdr. Sometimes backup will continue but lately its failing a lot.

This is the only article I found out saying that its a bug and there should be fix coming but.

We are running SQL2008 R2 SP2.

Is there any way to configure SQLbackup so it will not check for filestream.hdr?
