SVN备份/恢复脚本

上一篇介绍了svn的配置，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
#
#
# Description: SVN full backup of the project
# Author: Mr.chen
# Date: 2015/02/10
# Email:
#
#
SVN_BASICDIR = "/usr/local/svn/bin"
DAY = 5        # Backup files keep days
TIME = `date  + % Y % m % d % H % M`
SVNPATH = "/data/svn"
BAKDIR = "/data/svnbak"
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}
}

tar_bakfile() {
    cd ${BAKDIR}
    make_log  "tar zcf ${1##*/}.tgz ${1##*/}"
    tar zcf ${ 1 ##*/}.tgz ${1##*/} &> /dev/null

    make_log  "rm -rf ${1##*/}"
    rm  - rf ${ 1 ##*/} &> /dev/null
    cd
    echo "" >> ${BAKLOG}
}

rm_expired() {
    cd ${ 1 }
    _DAY_ = `date  - d "${DAY} days ago"  + % Y % m % d`
    ls | grep ${_DAY_} | xargs rm  - rf
    cd
}

ftp_upload() {
    #################################
    #FTP upload
    cd ${BAKDIR}
    #echo "Start upload file: `date`"

put $ 1
EOF

done

make_log  "=============== Start Backup ==============="
for  _bak_project_  in  ${PROJECT};do
    make_log  "${SVN_BASICDIR}/svnadmin hotcopy ${SVNPATH}/${_bak_project_} ${BAKPATH}/${_bak_project_}"

        echo  "Project ${_check_proejct_} backup file Invaild.Plz check..."
        ls  - ldh ${BAKDIR} / *  | grep  '^d'  | awk  '{print $NF}'  | xargs rm  - rf
        exit  123
    fi
done

# 从FTP的服务器下载备份脚本，并自动恢复到指定目录

有可能有很多不是很完善，如需要可以自己随便改改就行了。
