The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Incremental backups in Mysql

Asked by that1guy15 in MySQL Server

Tags:

I am needing to backup one of my databases on a Cent 5 box running mysql. I would like to run a full backup weekly and and daily backups of the binary logs. I have never done this before so i just want to make sure im configuring everything correctly.

To enable binary logging i edit /etc/my.snf and add the following
log-bin=/var/log/mysql/binary/mydatabase_log
binlog-do-db=mydatabase

Then restart mysqld

Then to run a weekly full i would do a mysqldmp and flush the logs
mysqldump --flush-logs mydatabse > mydatabasebkup.sql

Then on the daily incremental i would flush the logs and backup yesterdays log (this is were im unsure)
mysqladmin flush-logs
mv /var/log/mysql/binary/* /var/fileserver/backups/mydatabase001.log


Does this look correct? my concerns are:
1)in the my.cnf file, binlog-do only creates logs for that database, correct?
2)on the daily if i flush the logs does that delete the old log files or does it leave them in the directory


Thanks for the imputStart Free Trial
