Just for a future reference, mysql backup script:
@REM echo off @REM this script creates a backup of all the mysql databases in the designated directory. @REM Please provide day of a week as a parameter set file=d:Mysql_backup%1%_backup mysqldump -u backuper --all-databases > %file% 7z a %file%.zip %file% del %file%
-u backuper specifies the mysql user. This user must have a read access to all the databases. Provide a day of the week as a first argument.
