After the database server is set up, the first thing we need to do is not to consider which MySQL-carrying programs should be run on this database-supporting server, but when the database is damaged.

After the database server is set up, the first thing we need to do is not to consider which MySQL-initiated programs should be run on the server that supports the database, but when the database is damaged, how to safely restore to the last normal state, minimizing data loss. In other words, just the establishment of a database server can only describe what it can do, and it does not mean what it can do stably. Disaster

First, the introduction of rsync Rsync is a data mirroring Backup tool under the Linux system that enables you to back up local system data over the network to any remote host, and Rsync has the following characteristics: Can be mirrored to save the entire directory tree and file system Data can be incrementally synchronized, file transfer efficiency is high, so synchronization time is very short. You can keep attributes such as permissions, time, and so on for existing files. Encrypted tra

The driver can run back without a car (send an ACK response packet separately ), you can also bring some return messages to the destination region (TCP can include ack response information in reverse traffic to improve efficiency ). However, in a disaster tolerance system, data is alway

The default five kinds of FSMO exist on the first DC of the root domain in the forest, while the relative representation host, PDCE, infrastructure master in the child domain exists on the first DC in the child domain. After the construction of the previous domain, we will perform a disaster recovery for the primary domain controller. Step three: The transfer of FSMO r

With the rapid development of office automation and electronic commerce, the dependence of enterprise on information system is more and more high, and database plays an important role as the core of information system. Especially in some industries with high data reliability requirements such as banks, securities, telecommunications and so on, if there is an accidental downtime or loss of data will be very heavy. This database administrator should develop a detailed database backup and

If you're like most administrators, you might be responsible for backing up your Exchange database every night and storing your backup records in a secure location. This is great--but just taking these steps may not completely get you out of a serious disaster. In this article, I'll describe three of the most important and best ways to make a disaster recovery fo

data, as in the case of aof logs. So every piece of data just needs to be written once.Another reason is that the Rdb file storage format and the Redis data in memory encoding format is consistent, do not need to do data encoding work, so the CPU consumption is much smaller than the AOF log load.Second, disaster recovery simulationSince persistent data is used for data

mechanism, the client may read the old data in the standby node, if the business requires strong data consistency, you can set the read-only main option in the read request, so that the read request will be forwarded by the interface layer to the master node, in this case, the standby node is only used for disaster recovery, not provide services.In order to ensure the data consistency of the primary and st
