You must backup your data regularly. You should perform a backup as often as you change data. In Sequel Pro, this is performed from the Export menu item under the File menu. On the command line, you can do the same with:
/usr/local/mysql/bin/mysqldump --lock-tables=FALSE -h localhost -u Username -p music > music.bak_date
The –lock-tables=FALSE turns off lock-tables. If your username has permission to lock tables, you don’t need that.
You can also place that command line in a crontab file if you are familiar with cron. This will back up your data on a regular basis. Make sure you are not overwriting previous information, or you are likely to overwrite good information with bad information at precisely the time you needed your backup. Always archive your backups.
