Why do I need a delayed backup?Percona-xtrabackup is an excellent tool for incremental backups. The delayed backups we talked about today are also using their products.AB replication was previously mentioned in the MySQL AB replication article. Let's first review the key points of MySQL replication. AB replication is also known as master-slave replication, the implementation of data synchronization. After the following steps:

You can set some Oracle database-related settings and backup policies. For example, you can set the concurrent data streams transmitted to the disk drive, which can be based on the CPU configuration of the database server.

Once the primary router returns to normal, it will automatically switch back and take over data transmission again. Th

1 VRRP concept IntroductionVRRP is short for Virtual Router Redundancy Protocol ). To understand VRRP, determine the following terms:● VRRP router: the router that runs the VRRP protocol. This vro can be one or more virtual routers.● Virtual router: an abstract object managed by VRRP protocol, used as the default router of a host in a shared LAN. It consists of a vro identifier (VRID) and a group of associated IP addresses in the same LAN. One VRRP router can back up one or more vrouters.● IP ad
The benefits of using MySQL master-slave replication are:
1, the use of the master-slave server architecture, stability can be improved. If the primary server fails, we can use the server to provide services;2, in the master and slave server separately processing user's request, may enhance the data processing efficiency;3. Copy the data from the primary server to the server to protect the data from accidental loss;
