FIX: Storage device overhead when you back up data or log files to a network share in SQL Server 2014 or 2012

Symptoms

When you back up a database or a database log to a network share Universal Naming Convention (UNC) path in Microsoft SQL Server 2014 or Microsoft SQL Server 2012, the network storage device indicates that SQL Server searches for the filestream.hdr file in its parent directories. This generates some unexpected overhead on certain storage devices.

Cause

This issue occurs because SQL Server checks for the filestream.hdr file to prevent a file from being backed up to a FILESTREAM container. However, this is generally unnecessary for a network share.

Resolution

Cumulative update information

This fix relaxes the check for a UNC path.

The issue was first fixed in the following cumulative update of SQL Server:


Recommendation: Install the latest cumulative update for SQL Server

Status
