作为信息安全的一个重要内容数据备份的重要性却往往被人们所忽视。只要发生数据传输、数据存储和数据交换，就有可能产生系统失效、数据丢失或遭到破坏。如果没有采取数据备份和数据恢复手段与措施，就会导致数据丢失或损毁，给数据中心造成的损失是无法弥补与估量的。 数据故障的原因可划分为系统故障、事务故障和介质故障三大类。
造成数据丢失和毁坏的原因
1、数据处理和访问软件平台故障。
2、操作系统的设计漏洞或设计者出于不可告人的目的而人为预置的“黑洞”。
3、系统的硬件故障。
4、人为的操作失误。
5、网络内非法访问者的恶意破坏。
6、网络供电系统故障等。
从信息安全的角度出发，实际上第三方或敌方信息的入侵，也会产生不同程度的数据故障。这些因素将会造成的后果是数据丢失、数据被修改、增加无用数据及系统瘫痪等。数据中心就是要千方百计地维护系统和数据的完整性与准确性。通常所采取的措施有安装防火墙，防止黑客人侵;安装预防有毒软件，采取存取控制措施;选用高可靠性的软件产品；增强计算机网络的安全性等。但是，世界上没有万无一失的信息安全措施。因此，数据备份是保护数据的最后手段，也是防止主动型信息入侵的最后一道防线。
