---- Advantages of Hot Backup:
---- 1. Backup can be performed at the tablespace or data file level, with a short backup time.
---- 2. The database is still available during Backup.
---- 3. It can be restored in seconds (to a specific point in time ).
---- 4. Restore almost all database entities.

Use the main premise: the table's primary key is self increasing.
In a dual-master case, the ID will be the case, with the program specifying the ID write library m1:1,3,5,m2:2,4,6.

SummaryThe recovery of lost database files depends to a large extent on the backup strategy used. Based on the flexibility of recovery, this paper discusses the backup and

5. Low maintenance and high security.
However, cold backup also has the following shortcomings:
1. When used separately, only recovery at a certain time point can be provided.
2. During the whole backup process, the database must be backed up instead of other work. That is to say,

First, the foreword:
When the database server is established, the first thing we need to do is not to consider what MySQL-enabled programs are running on this database-supporting server, but how to recover to the last normal state after the database has been compromised, minimizing the loss of data.
Or, just the establishment of a database server, can only show what it can do, does not mean that it can be stable to do something. The efficiency and comprehensiveness of disaster
