一、全量備份

環境：一臺主SVN，一臺備SVN（主要提供備份功能），后續可通過鉤子腳本進行實時備份，后續發給大家。

工作原理：通過svn的hotcopy命令過行熱備份，并進行一系列的檢查，備份后通過rsync推送到備份機上。

腳本如下：

二、增量備份

環境：一臺主SVN，一臺備SVN（主要提供備份功能），后續可通過鉤子腳本進行實時備份，后續發給大家。

工作原理：

1、備機上通過nfs掛載到主機上，主要實現通過svnlook youngest來查看主和備間各版本庫的版本號差別。（掛載后相當于在本地一樣，就可以使用youngest參數或取到主和備版本號的區別別，并進行打包。）

2、掛載并打包后，將打包后的文件存放到掛載目錄中，在到備機上通過還原腳本分別對更新的版本庫進行還原，并將結果通過郵件發給告知人。

腳本如下：
