Backup All Databases

mysqldump -n --user=XXXX --password=XXXX --all-databases | gzip -c > server.sql.gz

Dump Data and Structure

mysqldump -u root -p --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com | sed 's/CREATE TABLE/CREATE TABLE IF NOT EXISTS/g' > io85_com_full.sql

Dump Data Only

mysqldump -u root -p --no-create-info --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com > data_dump.sql

Dump Structure Only

mysqldump -u root -p --no-data --skip-add-drop-table --replace --skip-extended-insert --lock-tables io85_com | sed 's/CREATE TABLE/CREATE TABLE IF NOT EXISTS/g' > schema_dump.sql

Select DB for Import

mysql -u root -p --one-database db_to_restore < fulldump.sql

Extract Database from Dump File

sed -n '/^-- Current Database: `test`/,/^-- Current Database: `/p' fulldump.sql > test.sql

Basic my.cnf
