linux下备份脚本主之 遍历目录备份所有二级目录文件
1,备份脚本如下,我这里以备份CVS目录为例,总CVS目录下有几个Project,统统备份
并且保留20份原始文档,恢复也很简单,拷贝回去接压缩即可,特别是权限等也不受到影响,
另外还有日志文件全程跟踪,你可以了解备份的具体时间,和期间遇到的问题。

2,上面这个脚本是本地备份,如果想异地备份
我这里也有几个办法,一个是NFS,另一个是SAMBA,还有一个是FTP,想NFS,SAMBA只需要挂载过来
即可,比如我们这里的/cvsbak,可是是挂载网络上的NFS,SAMBA目录,只要权限设置妥当,完全没有问题。
最后FTP,其实用smbclient访问时跟FTP差不多,在脚本的最后加上,登录的用户名密码再PUT上去即可,比如FTP的脚本如下:
