1、备份规则:

  在生产环境中有若干服务器需要定时将服务器中应用程序,以及数据库等进行备份。要求在本地服务器中保存近一周的备份,备份服务器中保存最近一月的备份文件。

                               

  以服务器A为例:在服务器A上有应用程序业务及(/ucap/UServer_V5.5.1_5002),有数据库业务(mongodb和mysql)需要将以上三个业务进行备份,且在A服务器上创建backup-dir将备份文件存放在目录下,每日凌晨进行备份,并将备份文件上传至备份服务器(NFS),在平时备份服务器与服务器A不会有联系,即只是在上传备份文件,服务器A自动挂载备份文件共享目录,备份完成卸载目录。本地服务器保存近一周文件,备份服务器保存近30日备份文件。

2、具体实现如下步骤:

  

 1 #delet backup when is sunday   周日删除上周文件。
 2 WEEK=$(date +%w)            
 3 BACKUP_ROOT=/backup
 4 BACKUP_DIR=/backup/backup_full_`date +%F`
 5 if [ -e $BACKUP_ROOT ]
 6         then
 7                 cd $BACKUP_ROOT  #如果/backup目录存在,进入目录。
 8      if [ $WEEK -eq 0 ]
 9                 then
10                         rm -rf $BACKUP_ROOT/* #如果进入是星期天(0表示星期天)执行删除/backup下所有的备份文件。
11      fi
12      if [ $? -eq 0 ]     #判断是否删除成功
13           then
14               action "old-backup is remove." /bin/true
15      fi
16  
17 fi
18 ####mkdir backup-dir    #创建本地备份目录。如果目录存在则输出目录已经存
19 #在,否则表示不存在目录则创建包含时间的目录文件目录
20 if [ -e $BACKUP_DIR ]    
21         then
22                 action "$BACKUP_DIR had been created."  /bin/true
23         else
24 #含当前时间的目录文件实际可以用$BACKUP_DIR
25                 mkdir -p /backup/backup_full_`date +%F`
26                 action "$BACKUP_DIR  is creating."  /bin/true
27 fi     
本地创建备份目录及周日删除

  注意:周日删除必须在创建当天目录之前。因为一旦先创建目录在删除文件由于使用的是rm -rf $BACKUP_ROOT/*意思是将本地备份目录下的所有文件删除,所有新创建的目录也会被删除。因此应该执行先删除再创建。

 1 ###tar backup  /ucap/UServer_V5.5.1_5002
 2 CMSP=/ucap
 3 cd $CMSP
 4 FILE_UCM=UServer_V5.5.1_5002
 5 #使用tar -g快照功能进行备份将快照snapshot.cms也存放在备份目录下,然后将备份文件按照ip地址以及日期进行打包存放在备份目录下的当日文件目录下。
 6 tar -g $BACKUP_ROOT/snapshot.cms -cvf $BACKUP_DIR/${FILE_UCM}_ip_1.25_backup.$(date +%F).tar  $FILE_UCM >/dev/null 2>&1
 7 
 8 if [ $? = 0 ]    #判断是否执行成功。
 9         then
10                 action "$FILE_UCM is backup." /bin/true
11         else
12                 action "$FILE_UCM is no been backuped." /bin/true
13 fi
14 ###tar backup  /ucap/mongodb
15 CMSP=/ucap
16 cd $CMSP
17 FILE_UCM=mongodb
18 #备份规则同上。
19 tar -g $BACKUP_ROOT/snapshot.cms -cvf $BACKUP_DIR/${FILE_UCM}_ip_1.25_backup.$(date +%F).tar  $FILE_UCM >/dev/null 2>&1
20 
21 if [ $? = 0 ]
22         then
23                 action "$FILE_UCM is backup." /bin/true
24         else
25                 action "$FILE_UCM is no been backuped." /bin/true
26 fi
