how to take phpmyadmin(mysql) backup database cron with date and time

Question

Answer 1

Since you want to make a cron you probably want to use mysqldump command.

mysqldump -u database_user -pdatabase-password database_name | gzip -9 > /path/to/backup/directory/database-data/$(date +%Y-%m-%d-%H.%M.%S).sql.gz

Your cron will look like this:

30 2 * * * mysqldump -u database_user -pdatabase-password database_name | gzip -9  /path/to/backup/directory/database-data/$(date +%Y-%m-%d-%H.%M.%S).sql.gz

In some systems like RHEL you might need to escape the characters from the date expression. https://unix.stackexchange.com/questions/8584/using-the-system-date-time-in-a-cron-script

add a \\ before each %. (\\%Y-\\%m-\\%d-\\%H.\\%M.\\%S)
