I use command.com backup macros to copy the contents of my HDD drive working directory on to a network drive every night.
Dyntax looks like
ECHO OFF
rem pause
D:
xcopy D:\_D_Method_0\*.* F:\_D_Method_0\ /D /Y /G /H /S
xcopy D:\_D_Method_1\*.* F:\_D_Method_1\ /D /Y /G /H /S
xcopy D:\_D_Method_2\*.* F:\_D_Method_2\ /D /Y /G /H /S
xcopy D:\_F_Method_3\*.* F:\_D_Method_3\ /D /Y /G /H /S
pause
It's a simple text file saved with a .bat extention. You can keep it on your desktop and make shortcuts to it.
It generally only copies a file if it's newer than the one there.
The number of files in the destination folder tends to keep growing but it's just a way to ensure a HDD failure cannot cost me more than a days lost work.
At home I perform a real HDD synchronization using Synchback Pro. It does a nice job.
