linux的svn备份脚本

需求：一个星期一次全备份，每天进行增量备份，备份文件远程传送到另一个文件服务器上，每天以邮件发送备份log。
脚本1：遍历多个版本库的备份脚本。

#svnbak.sh
#svn库名
proList=`cat svnlist.txt`
echo `date`
date=`date "+%Y-%m-%d"`
for name in $proList;
do
 echo $name
#调用备份脚本2
 ./bak.sh $name >> $date-log
done
#发送邮件
python3.7 ./Smtp.py $date-log

脚本2：版本库的备份。

# bak.sh
#echo `date`

set -x
#远程备份服务器的ip
remoteIp="10.10.94.44"

PRONAME=$1

if test -z $PRONAME
then
   echo "error proname is empty"
   exit 1
fi
#备份目录，脚本所在的目录，远程备份服务器也有此目录
SVNBAK=/home/svnbak

BAKDIR=$SVNBAK/$PRONAME

if [ ! -d "$BAKDIR" ]
then
 mkdir $BAKDIR
fi
#svn库所在目录
SVNDIR="/home/svn"
SVNPRO="$SVNDIR/$PRONAME"

echo $SVNPRO

date=`date "+%Y-%m-%d"`
week=`date "+%w"`

#发送文件到远程服务器，成功后删除文件
sendFile(){
 svnlook youngest $SVNPRO > $BAKDIR/lastVersion.txt
 file=$1
 if [ -s "$file" ];then
   #发送到远程服务器备份
   du -sh $file
   scp -r $file root@$remoteIp:$SVNBAK/$PRONAME-${file##*/}
   if [ $? -eq 0 ]; then
     echo "svn远程备份成功!"
     rm -rf $file
   else
     echo "Sending $file to remote is failed!"
   fi

 fi
}

#全备份
if [ $week = "2" ]
then
    file=$BAKDIR/svn_all.gz
    echo $file
    svnadmin dump $SVNPRO | gzip > $file
    if [ -s "$file" ];then
        sendFile $file
    fi
    exit 1
fi

#走增量备份

lastVersion=`cat $BAKDIR/lastVersion.txt`

let lastVersion=$lastVersion+1

echo "lastVersion:$lastVersion"

svnlook youngest $SVNPRO > $BAKDIR/nextVersion.txt

nextVersion=`cat $BAKDIR/nextVersion.txt`

echo "nextVersion:$nextVersion"

increFile=$BAKDIR/svn_increment_$lastVersion-$nextVersion-.gz

if [ $nextVersion -le $lastVersion ];then
   echo "无新的版本号更新"
   exit 1
fi

svnadmin dump --incremental -r $lastVersion:$nextVersion $SVNPRO | gzip > $increFile

if [ $? -ne 0 ];then
   exit 1
fi

sendFile $increFile

Python发送邮件脚本。注意：需要安装python3以上版本。

#Smpt.py
import os
import smtplib
import sys
from email.mime.text import MIMEText
from email.header import Header

def log_content():
    if len(sys.argv) == 1:
        print("log path is null:1")
        exit(1)

    path = sys.argv[1]

    if path is None:
        print("log path is null:2")
        exit(1)

    if path is None:
        print("log path is null:2")
        exit(1)

    if not os.path.exists(path):
        print("log file is not exist")
        exit(1)

    fp = open(path, "r")
    content = fp.read()
    fp.close()
    return content


# 第三方 SMTP 服务
mail_host = "smtp.@xx.com"  # 设置服务器
mail_user = "xxx"  # 用户名
mail_pass = "xxx"  # 口令

sender = 'xxx@xx.com'
receivers = ['xxx@xx.com']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

message = MIMEText(log_content(), 'plain', 'utf-8')
message['From'] = Header("congyl@neusoft.com", 'utf-8')
message['To'] = Header("congyl@neusoft.com", 'utf-8')

subject = 'svn备份'
message['Subject'] = Header(subject, 'utf-8')

try:
    smtpObj = smtplib.SMTP(host=mail_host, port=587)
    smtpObj.starttls()
    # smtpObj.set_debuglevel(1)
    smtpObj.login(mail_user, mail_pass)
    smtpObj.sendmail(sender, receivers, message.as_string())
    print("邮件发送成功")
except smtplib.SMTPException as e:
    print(e.args)
    print("============")
    print("Error: 无法发送邮件")

最后，三个脚本都需要在/home/svnbak下，执行：./svnbak.sh即可。
我是用jenkins每天凌晨定时执行脚本，当然你也可以用linux的定时任务执行。
