veeam instant recovery

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.

Xlog file. The server provides a process called pg_switch_xlog () to do this work:test=# SELECT Pg_switch_xlog ();Pg_switch_xlog----------------0/17c0ef8(1 row)You might call this process when some important patching work is done or you want to make sure that a particular database is securely present in your Xlog archive.3.5 SummaryIn this chapter, you've learned about instant recovery, a safe and easy way

Label:So far, you have mastered a certain theory. Because life is not only made up of theories (it can be equally important), it is time to delve into practical work. The goal of this chapter is to let you know how to recover data to a given point in time. This is important when your system crashes or someone accidentally deletes a table, does not replay the entire transaction log, but replays a small portion of it. Instant

Hot_standby is that archive does not need to know the currently running transaction. This information is critical in the case of convective replication. [Restart can be done by directly using pg_ctl–d/data_directory–m fast restart or through a standard init script.] ] The easiest way to check our archive work is to create some useless data in the database. The following code snippet shows a way to easily produce 1 million rows of data: test=# CREATE TABLE t_test as SELECT * from Generate_series

use instant recovery and do not need to start a backup, you can safely skip Xlog and save some space (default mode).Use traditional methods to create a basic backupNow Pg_basebackup is the most common way to get an initial copy of a database server. This is not always the case. Traditionally, a different approach has been used to work as follows:• Call SELECT Pg_start_backup (' some label ');• Copy all dat
