C#實現(xiàn)MySQL命令行備份和恢復

mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql

mysqldump -hhostname -uusername -ppassword databasename | gzip > backupfile.sql.gz

mysqldump -hhostname -uusername -ppassword databasename specific_table1 specific_table2 > backupfile.sql

mysqldump -hhostname -uusername -ppassword –databases databasename1 databasename2 databasename3 > multibackupfile.sql

mysqldump –no-data –databases databasename1 databasename2 databasename3 > structurebackupfile.sql

mysqldump –all-databases > allbackupfile.sql

mysql -hhostname -uusername -ppassword databasename  backupfile.sql

gunzip  backupfile.sql.gz | mysql -uusername -ppassword databasename

mysqldump -uusername -ppassword databasename | mysql –host=*.*.*.* -C databasename
