最全最强悍的linux自动备份+自动删除老的备份脚本
先新建一个backup.sh的文件 在把下面的内容添加进去改改实际路径
做个计划任务就自动备份了 命令：crontab -e
#!/bin/bash
#backup.sh
#备份至/root/bak/
BackupPath=/root/bak/
LogFile=/root/bak/back.log
DBPath=/usr/local/app/ #需要备份的目录
NewFile="$BackupPath"app_back$(date +%y%m%d).tgz
DumpFile="$BackupPath"app_back$(date +%y%m%d)
OldFile="$BackupPath"app_back$(date +%y%m%d --date='7 days ago').tgz
echo "-------------------------------------------" >> $LogFile
echo $(date +"%y-%m-%d %H:%M:%S") >> $LogFile
echo "--------------------------" >> $LogFile
Delete Old File
if [ -f $OldFile ]
then
rm -f $OldFile >> $LogFile 2>&1
echo "[$OldFile]Delete Old File Success!" >> $LogFile
else
tar cpzvf $NewFile $DBPath >> $LogFile 2>&1
echo "[$OldFile]No Old Backup File!" >> $LogFile
fi
if [ -f $NewFile ]
then
echo "[$NewFile]The Backup File is exists,Can't Backup!" >> $LogFile
# tar pczvf $NewFile $DBPath >> $LogFile 2>&1
echo "[$NewFile]Backup Success!" >> $LogFile
else
tar cpzvf $NewFile $DBPath >> $LogFile 2>&1
fi
如果有多个目录需要备份则多把那几个变量复制下 在改个参数就可以了
下面是mysql数据库自动备份脚本
参数按照你们实际的路径
#!/bin/bash
#备份至/root/dbxxxxx.tgz
#This is a ShellScript For Auto DB Backup
#Powered by aspbiz
#Setting
DBName=mysql
DBUser=root
DBPasswd=123456
BackupPath=/root/
LogFile=/root/db.log
DBPath=/var/lib/mysql/
#BackupMethod=mysqldump
#BackupMethod=mysqlhotcopy
#BackupMethod=tar
#Setting End
NewFile="$BackupPath"db$(date +%y%m%d).tgz
DumpFile="$BackupPath"db$(date +%y%m%d)
OldFile="$BackupPath"db$(date +%y%m%d --date='30 days ago').tgz
echo "-------------------------------------------" >> $LogFile
echo $(date +"%y-%m-%d %H:%M:%S") >> $LogFile
echo "--------------------------" >> $LogFile
#Delete Old File
if [ -f $OldFile ]
then
rm -f $OldFile >> $LogFile 2>&1
echo "[$OldFile]Delete Old File Success!" >> $LogFile
else
echo "[$OldFile]No Old Backup File!" >> $LogFile
fi
if [ -f $NewFile ]
then
echo "[$NewFile]The Backup File is exists,Can't Backup!" >> $LogFile
else
case $BackupMethod in
mysqldump)
if [ -z $DBPasswd ]
then
mysqldump -u $DBUser --opt $DBName > $DumpFileelse
mysqldump -u $DBUser -p$DBPasswd --opt $DBName > $DumpFile
fi
tar czvf $NewFile $DumpFile >> $LogFile 2>&1
echo "[$NewFile]Backup Success!" >> $LogFile
rm -rf $DumpFile
;;
mysqlhotcopy)
rm -rf $DumpFile
mkdir $DumpFile
if [ -z $DBPasswd ]
then
mysqlhotcopy -u $DBUser $DBName $DumpFile >> $LogFile 2>&1
else
mysqlhotcopy -u $DBUser -p $DBPasswd $DBName $DumpFile >>$LogFile 2>&1
fi
tar czvf $NewFile $DumpFile >> $LogFile 2>&1
echo "[$NewFile]Backup Success!" >> $LogFile
rm -rf $DumpFile
;;
*)
/etc/init.d/mysqld stop >/dev/null 2>&1
tar czvf $NewFile $DBPath$DBName >> $LogFile 2>&1
/etc/init.d/mysqld start >/dev/null 2>&1
echo "[$NewFile]Backup Success!" >> $LogFile
