how to add date and time with backupfile name using mysqldump from command prompt and to define the path of backupfile

问题

Im using this command for backup from mysqldump

mysqldump -uroot -ptrackerdb) --alldatabases >test.sql

Now i want to add date-time with my backup file like current date and time e.g test_25July2013_13:00

For this i add test_date +%Y-%m-%d_%H-%M-%S.sql in file name but it gives error

'Couldn't find table': date +%Y-%m-%d_%H-%M-%S`

What I'm doing wrong here?

I'm using that:

LINUX

mysqldump -u <user> -p <database> | bzip2 -c > <backup>$(date +%Y-%m-%d-%H.%M.%S).sql.bz2

WINDOWS (googled it, because i have been using LIN only)

@echo off
cls
echo Date format = %date%
echo dd = %date:~0,2%
echo mm = %date:~3,2%
echo yyyy = %date:~6,4%
echo.
echo Time format = %time%
echo hh = %time:~0,2%
echo mm = %time:~3,2%
echo ss = %time:~6,2%
echo.
echo Timestamp = %date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%

%mysqldir%\mysqldump -u %mysqluser% -p%mysqlpassword% -h %mysqlhost% -P %mysqlport% --databases --routines --verbose gnucash_shockwave > %BackupDir%\gnucash_shockwave-%timestamp%.sql

In Microsoft Windows, run below command in CMD

mysqldump -u USERNAME -pYOURPASSWORD --all-databases > "C:/mysql_backup_%date:~-10,2%-%date:~-7,2%-%date:~-4,4%-%time:~0,2%_%time:~3,2%_%time:~6,2%.sql"

Output file will look like,

mysql_backup_21-02-2015-13_07_18.sql

If you want to automate the backup process, then you can use Windows Task Scheduler, and put above command in .bat file - task scheduler will run the .bat file at specified interval.

mysqldump -u Database Username --password=Database password --all-databases |gzip > /home/username/MySQLDBBK$(date +%Y_%m_%d__%H_%M_%S$%M%S).sql.gz

this Cmd is Working.
