svn备份和还原

1 svn完全备份脚本的书写

vi  /data/myscripts/fullsvnbackup 内容如下：

#!/bin/bash
#author:liuhaiqing
#date:20110719
riqi=$(date +'%Y%m%d')
backupdir=/data/svnback
mkdir -p $backupdir/$riqi
old=$(svnlook youngest /data/svn/repos/test/)
echo "$old" >/tmp/oldnumber
svnadmin dump /data/svn/repos/test --revision 0:$old --incremental >$backupdir/$riqi/0-"$old"svn.bak

2 svn增量备份脚本书写

vi /data/myscripts/zengliangsvnbackup

#!/bin/sh
riqi=$(date +'%Y%m%d')
backupdir=/data/svnback
mkdir -p $backupdir/$riqi
old=$(cat /tmp/oldnumber)
new=$(svnlook youngest /data/svn/repos/test/)
if [ $old = $new ]
then
echo "svn don't need backup"
else
b=$(expr 1 + $old)
echo "$new" >/tmp/oldnumber
svnadmin dump /data/svn/repos/test --revision $b:$new --incremental >$backupdir/$riqi/"$b"-"$new"svn.bak
fi

3 增加计划任务

0  3  * * * sh /data/myscripts/fullsvnbackup
0  8-20/2 * * * sh /data/myscripts/zenglingsvnbackup

4 svn还原

恢复顺序从低版本逐个恢复到高版本；即，先恢复最近的一次完整备份，然后恢复紧挨着这个文件的增量备份

 

cd /data/svn/repos/
svnadmin create test2
svnadmin load test2 </data/svnback/20110719/0-1112svn.bak
svnadmin load test2 </data/svnback/20110719/1113-1113svn.bak
chown -R daemon.daemon test2

至此恢复成功

5 附上脚本，以免复制粘贴出问题
