Windows batch file error when backing up Sql database - mysql

Question

the error is after the
del "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql"
Here's the source code:
CLS
SET backuptime=%DATE:~10,4%-%DATE:~7,2%-%DATE:~4,2%-%TIME:~0,2%-%TIME:~3,2%
echo %backuptime%
echo Running dump ...
set 7zip_path=
"C:\xampp\mysql\bin\mysqldump.exe" --host="localhost" --port="3306" --user="jakedean" --password="jakedean" -Q --result-file="C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql" jakedean
echo Zipping ...
"C:\Program Files\7-Zip\7z.exe" a -tzip "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.zip" "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql"
echo Deleting the SQL file ...
del "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql"
timeout /t 5
echo Done!
#pause
and here's a print screen of the cmd prompt after executing...
I've tried everything from changing files names, shortening the directory, changing the non caps but nothing has worked... :/

Answer 1

Your problem is that the %backuptime% variable is generating slashes, you should find a way to remove them, since windows doesn't allow files with a slash in it's name. That's what's bugging your command.
List of unsupported characters:
Check the file name in the directory before you attempt to delete it.

I fixed this by replacing the
SET backuptime=%DATE:~10,4%-%DATE:~7,2%-%DATE:~4,2%-%TIME:~0,2%-%TIME:~3,2%
with
SET backuptime=%TIME:~0,2%-%TIME:~3,2%
The date was adding a / which isn't allowed in file names which caused the error. Also the date wasn't setting the correct data, it kept setting 01-02...
The whole .bat file now looks like this
#echo off
CLS
SET backuptime=%TIME:~0,2%-%TIME:~3,2%
echo %backuptime%
echo Running dump ...
set 7zip_path=
"C:\xampp\mysql\bin\mysqldump.exe" --host="localhost" --port="3306" --user="jakedean" --password="jakedean" -Q --result-file="C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql" jakedean
echo Zipping ...
"C:\Program Files\7-Zip\7z.exe" a -tzip "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.zip" "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql"
echo Deleting the SQL file ...
del "C:\backupforalldbs\tpsdatabase\bk_%backuptime%.sql"
timeout /t 5
echo Done!
