First of all, I would like to understand about the next logical backup and physical backup.
Logical backup and physical backup advantages and disadvantages, in general, physical backup faster recovery, a relatively large space, the backup logic slower, relatively small space. High cost recovery logical backup.
Logical backup is a backup sql statement, perform a backup at the time of recovery of the database sql statement to achieve reproducible data.
mysqldump
mysqldump is the use of SQL-level backup mechanism, he will lead into the data table SQL script file, is the most common logical backup method.
Physical backup
Physical backup is to back up data files, compare the image point is the next cp data files, but the real time nature is not backed up the cp so simple.
Well, after the previous very detailed introduction, I later learn is the main logical backup.
1, the logical data backup mysqldump
mysqldump -uroot -p --all-databases > all.sql
Back up all content databases
mysqldump -uroot -p --databases new3 hz1901> all.sql
backup new3 hz1901 two databases
mysqldump -uroot -p new3 > all.sql
Backing up a single database new3
mysqldump -uroot -p new3 info >all.sql
Backup library new3 table below info
2, data recovery
mysql -uroot -p < all.sql

Wait for the follow-up have time to learn.
