上一篇介绍了 svn 的配置（见 http://www.linuxidc.com/Linux/2015-02/113177.htm），这里就写了两个脚本对 svn 进行全备和恢复，由于是全备，所以可以做个计划任务，每天执行一次即可。保留几天的数据。

1、备份脚本：
#!/bin/sh

BAKPATH=${BAKDIR}/${TIME}
BAKLOG=${BAKDIR}/bak_svn.log
PROJECT=`/bin/ls -lh ${SVNPATH} | grep -E “^d” | awk ‘{print $NF}’`
CONIFIG_FILE=`/bin/ls -lh ${SVNPATH} | grep -E “^-” | awk ‘{print $NF}’`

! type lftp &> /dev/null && echo “Lftp command does not exist,Plz install lftp.” && exit 128

[! -d “${BAKPATH}” ] && mkdir -p ${BAKPATH}

make_log() {
/bin/echo -e “[$(date +%Y-%m-%d’ ‘%H:%M:%S) ] ${1}” >> ${BAKLOG}
