Use two of > .

Example:
Code: [Select]echo Backup completed at %time:~0,8% >>"C:\test.txt"

One ">" MEANS redirect output the following file, and if it already exists then OVERWRITE it.

Two ">", as in ">>" means redirect output to the following file and if it already exists, append to it.

Additionally, here is something to try:
With > or >> , it is implicit that if the file to write to does not already exist, then create it.
Thus, your "copy nul.... " line is not necessary.

I hope this helps.
