摘要
数据容灾是在异地建立和维护一个备份数据中心,利用地理分散性保证数据对于灾难事件的抵御能力。当出现数据丢失、硬件故障或误操作等问题时,马上切换到备份数据中心,不会影响应用服务;当不可抗自然灾难出现时,备份数据中心保证历史数据不会丢失,提供安全可靠的备份保护,并能够在灾难发生后快速恢复数据和应用,保证业务的连续运行。
Data disaster recovery is to establish and maintain an off-site backup data center to protect data against catastrophic events by making use of geographic discreteness.In case of data loss,hardware failure or misuse,the backup data center is immediately connected,so that the application services will not be affected.When earthquakes and other natural disasters occur,the backup data center ensures that historical data is not lost,providing secure and reliable backup protection,and has the ability to quickly recover the data and applications after disaster to ensure business to continue.
