If a new backup starts at that time, ntbackup.exe reports the following error (and quits): "The device reported an error on a request to write data to media." If the same backup job saves files to a MS Windows shared directory, a large backup file can be deleted much faster. After adding "strict allocate = yes" in /etc/samba/smb.conf (and restarting Samba) I haven't seen any improvement. ]]> http://software.intel.com/en-us/articles/windows-client-cifs-behavior-can-slow-linux-nas-performance/#comment-35097 Fri, 20 Nov 2009 01:29:32 -0800 http://software.intel.com/en-us/articles/windows-client-cifs-behavior-can-slow-linux-nas-performance/#comment-35097
