在各种网络操作系统中,都内置了一些备份工具,如NetWare操作系统中提供了Sbackup工具,在Windows NT操作系统中提供了NT Backup工具,在Unix操作系统中提供了tar命令来实现备份操作。那么,系统管理员们就必然面对这样一个问题:既然我的操作系统中已经有了备份工具,我还有没有必要使用专业的备份软件,如ARCserve呢? 我们暂且不去讨论这个问题的答案。我们都知道,备份就是为了保护无形的固定资产——数据,就像给有形固定资产投保一样,一旦没有病毒的攻击、电源故障、人为错误或自然灾害等发生从而导致数据丢失,它可能和保险单一样一点作用也不起,但有一点不同的是,对有形固定资产投保可能特别简单,只需支付一定的费用和履行一定的手续,而数据备份不会如此简单,因为数据总在不停地被修改或增加,因此,我
In a variety of network operating systems, some built-in backup tools, such as NetWare operating system provides a Sbackup tool in the Windows NT operating system provides NT Backup tools, in the Unix operating system provides a tar command to achieve the backup operation . Then, system administrators are bound to face such a problem: Since I have a backup tool in the operating system, I still have no need to use professional backup software, such as ARCserve? Let’s not discuss the answer to this question . We all know that the backup is to protect the intangible fixed assets - data, just like tangible fixed assets insurance, as long as there is no virus attack, power failure, human error or natural disasters, which will lead to data loss, it may insurance The same can not be said for a single role, but the difference is that it can be particularly simple to insure tangible fixed assets, paying only a certain fee and performing certain formalities, and data backup will not be as simple as data is always on the go The ground is modified or increased, so I
