使用svnsync備份很簡單，步驟如下：
一、在備份機上創建一個空庫：svnadmin create SMP
二、更改該庫的鉤子腳本pre-revprop-change（因為svnsync要改這個庫的屬性，也就是要將源庫的屬性備份到這個庫，所以要啟用這個腳本）:
cd SMP/hooks;
cp pre-revprop-change.tmpl pre-revprop-change;
chmod 755 pre-revprop-change;
vi pre-revprop-change;
將該腳本后面的三句注釋掉，或者干脆將它弄成一個空文件。
三、初始化，此時還沒有備份任何數據：
svnsync init file:///home/backup/svn/svnsync/SMP/ http://svntest.subversion.com/repos/SMP
語法是：svnsync init {你剛創建的庫url} {源庫url}
注意本地url是三個斜杠的：///
四、開始備份：
svnsync sync file:///home/backup/svn/svnsync/SMP
這是就一個個版本進行備份了。

可能的報錯一：

svnsync: Couldn't get lock on destination repos after 10 attempts
這個時候可能屬性被鎖了，刪掉屬性：
svn propdel svn:sync-lock --revprop -r0 file:///home/backup/svn/svnsync/SMP
刪除成功后，再試一遍基本就可以了。
如果反復操作都是同樣錯誤的話，有可能是你的svn安裝的有問題，重新安裝一遍就好了，俺就是這樣。

可能報錯二、
svnsync: REPORT request failed on 'http://svn1.subversion.com/repos/Relevance'
svnsync: The requested report is unknown.
這是因為你源庫的版本太低了，svnsync所需要的函數Report是svn1.4后加入的。沒辦法，對你的庫進行升級后才能備份。

由于執行svnsync sync file:///home/backup/svn/svnsync/SMP 過程中容易出現錯誤一，避免中途人工干預，我寫了一個腳本，來自動修復錯誤。腳本里面的路徑自己來修改吧，我的環境是本地備份到另外一個硬盤。
