Re: how to dump database or tables
*Make a backup of yours databases:* shell> mysqldump -u -p --all-databases -e > path/file.dmp Implicit to this command quoted above, you will have the --opt option ( shorthand for --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset ) and -e ( use multiple-row INSERT syntax that include several VALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded ). Consider to use -e option when you have a big backup - *you will get more faster restore*, improving the time-recovery. *Make a backup of a table:* shell> mysqldump -u -p mysql user -e > path/file.dmp In this last way, you will copy to a file only a table of mysql database - its simply like that. *Restore the backup:* To restore, use mysql client, like this... shell> mysql -u -p < path/file.dmp Other considerations regards of the operations of restore a backup is to apply the correct O_DSYNC innodb_flush_method to InnoDB, disable foreign key checks and autocommit. These practicals will execute you backup faster then other way. When you use MyISAM, configure in my.cnf the bulk_insert_buffer_size with a value big enough and don't worry, start restore and be happy. *See it on manual:* http://dev.mysql.com/doc/refman/5.0/en/innodb-tuning.html -- Wagner Bianchi - Web System Developer and Database Administrator Phone: (31) 8654-9510 / 3272-0226 E-mail: wagnerbianch...@gmail.com Lattes: http://lattes.cnpq.br/2041067758113940 Twitter: http://twitter.com/wagnerbianchi Skype: infodbacet 2010/1/29 Anand kumar > it should be windows.. . > > On Fri, Jan 29, 2010 at 2:29 PM, Suresh Kuna >wrote: > > > Which OS your are using ? > > > > Suresh Kuna > > MySQL DBA > > > > On Fri, Jan 29, 2010 at 2:25 PM, muralikrishna g > > wrote: > > > > > i am working on my pc with mysql-5.0.27-community-nt > > > > > > i have created several data bases and tables in that.. to take backup, > we > > > have to use dump., i dont know the correct syntax how to use dump to > take > > > backup to a specific location., after that how to resore. please help > me > > > regarding this. > > > thanks in advance > > > > > >
