Re: Questions about Mysqldump
Adarsh, 1) When restoring a mysqldump you have the option of which database to restore. mysql database1 backup.sql 2) You might be able to use the --ignore-table command. I'm not sure if this would work mysqldump --all-databases -q --single-transaction --ignore-table=databasetoignore.* | gzip /media/disk-1/Server11_MysqlBackup_15September2011/mysql_15sep2011backup.sql.gz 3) The docs are here for mysqldump, might be worth a read: http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html HTH, Chris On 15/09/11 06:29, Adarsh Sharma wrote: Dear all, Today i backup my all databases (25) by using the below command :- mysqldump --all-databases -q --single-transaction | gzip /media/disk-1/Server11_MysqlBackup_15September2011/mysql_15sep2011backup.sql.gz Now I have some doubts or problems that I need to handle in future : 1. Is there any option in restore command ( I use mysql backup.sql ) to store only specific 1 or 2 databases out of this big backup file. 2.

What are the settings that are need to changed in my.cnf to make backup restore faster.

Re: Questions about Mysqldump
or u can use for loop, have only the database to be exported and use that variable in --database and do mysqldump of each database.
