svn dump 全自动备份脚本-白红宇

最近要给美国的SVN服务器做升级，由于这台服务器有一定年份了，在本公司也算是个三朝元老，保存了多少code啊！。为了保险起见，老板将迁移的工作郑重的交到我的手上。在欣欣然的同时也颤抖着。

不过还好我已经对其轻车熟路，在新的服务器上安装好apache和subversion软件后，开始着手备份与迁移了。

由于旧服务器版本太低，没有svnsync的功能，考虑再三，我选择使用了svnadmin dump去做备份。

可是有一个问题了，每个库的版本都有几万了，然后服务器上有十几个库，我可没耐心一个个输入svnadmin dump去备份它们，那会让我觉得长夜漫漫，难于睡眠！

管理员的最高境界就是花力气去懒惰，我很向往这个境界。所以，我花了些时间写了个shell，就让系统自己去干这些事情吧！

shell功能：

只需要大家修改源库所在的目录，和备份存放的目录就可以了。

第一次运行会全部备份，然后以后每次运行会增量备份。

所以，恢复的时候，先恢复全部备份，然后依次按照日期恢复增量备份即可。
