veeam replication best practices

Veeam Backup Replication synchronization is different from the mechanism of backup, synchronization is to crawl the virtual machine directly to the other end, the equivalent of a full standby, and then according to the scheduled task to take a snapshot, and based on the configuration to retain the most recent snapshots for failover recovery, This example synchronizes from a 61ESXi host to a 70ESXi host.1.

MySQL replication (2) Master-Slave replication practices, mysqlmaster-slave1. Preparations First, prepare two machines to install mysql My version here is 5.1.73, mysql database installation refer to: http://www.cnblogs.com/tangyanbo/p/4289753.html Centos for linux The machines are: Master: 192.168.1.227 Slave: 192.168.1.225 Scenario: master and slave are b

partMaster_log_file file corresponding to masterMaster_log_pos corresponding to master positionRun command: mysql>show slave status\gSlave_io_state, slave_io_running, and slave_sql_running indicate that Slave has not started the replication process. The location of the log is 4 instead of 0, because 0 is only the start of the log file, not the log location. In fact, MySQL knows the location of the first event is 4.Start copying, Run command:mysql> st

architecture, usually the better way is through the program code and middleware, such as planning, such as setting the table data to increase the increment of the ID value of the growth and other ways to implement two or more primary servers, but must pay attention to ensure that the integrity of these primary server data, Otherwise, the effect will be worse than a plurality of master-slave architectures;The stability of 5.mysql-cluster is not too good;6.Amoeba for MySQL is a good middleware so

MySQL semi-synchronous replication practices Semi-synchronous ReplicationMySQL master-slave replication only supports asynchronous replication before MySQL 5.5. That is to say, after the master database executes some transactions, no matter the progress of the slave database, the biggest advantage of this method is fa

MySQL disk replication technology-DRBD: advantages and disadvantages comparison, precautions and Best Practices DRBD is the block-level synchronous replication technology implemented by the kernel module. The synchronization level here can be adjusted because DRBD uses the NIC for block replication. If, using Infiniban

DrbdIt is the block-level synchronous replication technology implemented by the kernel module. The synchronization level here can be adjusted. Because drbd uses the network card for block replication. If InfiniBand is used for transmission, high concurrency can be effectively processed. This is a type of replication and storage. It is nothing more like a hot stan
