Batch - Error when renaming a file to timestamp - batch-file

Question

I have a program that takes EVERYTHING from the directory
C:\Users\Hensel\Desktop\mc-server\world, and it then it copies and pastes it in a separate directory
C:\Users\Hensel\Desktop\backups\
Then it renames the file called 'world' that it copied and renames it to a date/timestamp format.
#echo off
:backup
xcopy C:\Users\Hensel\Desktop\mc-server\world C:\Users\Hensel\Desktop\backups\world /I /E /Y /D
ren world Logs-%date:~10,4%%date:~7,2%%date:~4,2%_%time:~0,2%%time:~3,2%
ping localhost -n 2700 >nul
goto backup
But whenever I run it (I execute it within the backups directory), it returns the error of: "The syntax of the command is incorrect." Whenever I remove the line that renames 'world' it works fine, but the files won't have unique names when they are backed up unless it has a date and timestamp.

Answer 1

Without knowing your exact date/time format, I'd judge that you have spaces in the new filename.
try
set "newname=Logs-%date:~10,4%%date:~7,2%%date:~4,2%_%time:~0,2%%time:~3,2%.txt"
set newname=%newname: =0%
ren world %newname%
and if that doesn't work (which it should) then tell us what happens with
echo newname="%newname%"
which should be inserted just before the REN
So the full new file should be:
#echo off
:backup
xcopy C:\Users\Hensel\Desktop\mc-server\world C:\Users\Hensel\Desktop\backups\world /I /E /Y /D
set "newname=Logs-%date:~10,4%%date:~7,2%%date:~4,2%_%time:~0,2%%time:~3,2%.txt"
set newname=%newname: =0%
ren world %newname%
echo newname="%newname%"
ping localhost -n 2700 >nul
goto backup
where the echo newname="%newname%" line is optional
Meanwhile, in place of your PING line, you could try
timeout /t 2700 >nul
for a 45-minute delay in an "approved" manner.
