Method 1
something like
0 0 * * * /path/to/mysqldump ... > /path/to/backup/mydata_$( date +"%Y_%m_%d" ).sql
should work.
Please read
- man date
- man 5 crontab
Method 2
Create a cron.sh file with this content:
mysqldump -u root -p{PASSWORD} DBNAME 2>> "/filename_`date '+%Y-%m-%d'`.sql"And give the Read permission or full access permission for that cron.sh file.
and add this line into crontab file ($ crontab -e)
0 0 * * * cron.sh
