EMC NW disaster and recovery simulation2

To use EMC NW NMM to backup MS SQL always on database, that is a simple and safe way to protector data. Here is an example. node1,node2,node3 they are physical server name node is windows cluster name group1 and group 2 are always on group name so, w

As we said, sqlsever fail over cluster is perviously version of always on. The HA was guarenteed by OS not database. Therefor, we can not use windows cluster name as client name, because there is no windows cluster name in system. How and what to do

Simple step for EMC NW & NMM (1) disable WINDOWS UAC (reboot)(2) SET windows domain user AS sysadmin(3) modify hosts(4) install software (NW , NMM) (reboot)(5) CONFIG NWDROP VIEW [partition_show]GO SET ANSI_NULLS ONGO SET QUOTED_IDENTIFIER ONGO CREAT

High availability 和disaster recovery不是一回事. 尽管在规划和解决方案上有重叠的部分, 它们俩都是business contiunity的子集. HA的目的是在主数据中心内部, 提供弹性(resiliency)支持和计划允许内的宕机的时间. DR的目的是使得一个组织能在第一个数据中心发生灾难且影响到了基础设施的可用性的时候, 在第二个数据中心恢复计算机的正常使用.   High availability and disaster recovery are no

In this blog, I’ll look at how to do MySQL point in time recovery (PITR) correctly. Sometimes we need to restore from a backup, and then replay the transactions that happened after the backup was taken. This is a common procedure in most disaster rec
