veeam replication

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.

Two ways to back up Veeam Veeam creates two backup files, VBK is a full backup, and Vrb/vib is an incremental backup file used to record changes.Reversed Incremental BackupEach incremental backup updates the VBK file, and VBK is the latest full backup, restoring the latest backup as long as the VBK is restored. The modified content in VBK is saved to VRB in each incremental backup, so it is called REVERSED

Overview replication is usually used to create a copy of the master node to ensure high availability by adding redundant nodes. Of course, replication can also be used for other purposes, such as reading and analyzing data on the slave node. In horizontally Scalable businesses, replication is easy to implement, mainly in the use of the master node for write opera

MySQL replication is divided into master-slave replication and master-master replication. What is master-slave Replication refers to a master server with one or more servers as the slave servers. The slave server does not write any data. The data source is the master server. The purpose of

MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. The purpose of the

This article demonstrates how to build the most basic transactional replication.Environment Preparation: 2 virtual machines:The server names are Repa and Repb,repa are publishers, and REPB are subscribers. Are installed WindowsServer 2008r2 English version (the reason for working in a foreign company). and ensure that the two servers can exchange visits.SQL Server:In the above virtual machine, install SQL Server R2 x64 English Enterprise Edition separately.Demo Database:Microsoft Sample Database

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be located in different network topologies. Due to the powerful mysql replication function, th

The previous blog said how to use Xtrabackup to back up and restore databases. After the database has been restored, the two machine databases are the same, including Binlog file and Pos.At the same time, after the Xtrabackup backup is completed, the relevant Binlog file and POS information has been written to the backup information file, and the cat can view it under Linux. Then execute the Change Master command on the standby to successfully build the master-slave

MariaDB's GTID replication and multi-source replication, mariadbgtid Replication What is GTID? GTID is the global transaction ID (global transaction identifier). It was initially implemented by google and officially added to MySQL in MySQL 5.6. GTID is actually composed of UUID + TID. UUID is the unique identifier of a MySQL instance. TID indicates the number of

Label:synchronous, asynchronous, semi-synchronous replication comparison:Synchronous replication: Master commits the transaction until the transaction is committed at all slave, and the client is returned, and the transaction is completed. Disadvantage: There can be a significant delay in completing a transaction.Asynchronous replication: Requests Binlog to Maste

, 3, 5] [1, 2, 3, 5]Here, both variables A and B point to the same object (a list). Therefore, once you modify either of them, the other one will also be affected. in any case, the original object will be modified.Note:To become a python expert, the first thing to note is the change operation and assignment of objects, which are all reference operations on objects. A statement such as a = [] re-binds a to a new object, but does not affect the previous object. however, object

It can completely copy data from one MySQL Server Instance to another MySQL Server Instance

The so-called "copying objects" generates a "sibling brother" that is exactly the same as the specified object ". For object replication, there are two scenarios: shallow replication and deep replication. 1. Shallow copy: when the field value of the object is copied, the object referenced by the field will not be copied. For example, if an object has a fiel

Asynchronous replication: MySQL natively supports one-way, asynchronous replication. Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has been confirmed. Typically, this delay is dete
