3. 定制备份计划任务

0 1 * * 0 /data/shell/fullbackup.sh
0 * * * * 1-6 /data/shell/addbackup.sh
[root@ape-bz2009 ~]# cd /data/shell/
[root@ape-bz2009 shell]# chmod +x fullbackup.sh 4.执行备份脚本
#!/bin/bash
#定义用户和密码

#定义备份目录
databackupdir=/data/backup

#定义备份日志文件

echo "BackupFileName:$databackupdir.gz"

else

4.在备份服务器上进行日志清理
#!/bin/bash
#定义备份目录
databackupdir=/data/backup
addbackup=/data/addbackup
sqldelete( )
{
if [ -d $databackupdir ]
then
find $databackupdir -type d -ctime +7 -ok -exec rm {} \;

else
echo "please mkdir databackupdir!"

then

}
sqldelete
