The invention discloses a database system and a data synchronization method thereof and relates to the field of data bases. The database system comprises a host machine and a standby machine which is connected with the host machine, wherein the standby machine is used for copying data from the host machine, and when the standby machine can not copy the data from the host machine, the standby machine is used for selecting other standby machines to connect according to a predetermined strategy and copying the data from connected standby machines. According to the database system and the data synchronization method of the database system, when the host machine can not be directly as a copy source for the standby machine, the standby machine is capable of selecting other suitable standby machines to be as the copy source, so that the defects that in an existing database system, only the host machine is regarded as the copy source, as the result, the copy source is simplex, and data consistency and performance of a whole cluster is poor are overcome. Data consistency and performance of the database system is effectively improved.
