No I did not have a backup. But now I will have backup using the AT command of NT Dos. I set it up for a backup on avery day.

c:\>At 23:00 /every:1 xcopy c:\mywork\*.* C:\mybackup\*.* /s /e /c

I lost 20 hrs of work because I was a S. F.! :)

>Do you have a backup copy? At least of the previous day? On our work our system administrator makes backup copies of the whole developer server at the end of the day.
