BESR(SSR2011)如何备份及恢复LINUX系统

赛门铁克的BESR是一款强大的操作系统备份与恢复的软件，现最新的版本叫SSR2011，但关于其备份与恢复LINUX系统的资料较少。这些实施了一个项目，记录下来与大家分享。

环境描述：WINDOWS主机192.172.11.246建一共享文件夹ssr,linux为RHEL5.4，做了LVM。

具体操作步骤如下：

挂载cifs文件（挂载192.172.11.246/ssr共享文件夹）

[root@rhel /]# mount -t cifs -o username=administrator,password=dghr@0769 //192.172.11.246/ssr /media/

查看卷状况

[root@rhel media]# df -h
/dev/mapper/VolGroup00-LogVol00
                       15G  2.8G   12G  21% /
/dev/hda1              99M   20M   74M  22% /boot
tmpfs                 3.2G     0  3.2G   0% /dev/shm
none                  3.2G   40K  3.2G   1% /var/lib/xenstored
//192.172.11.246/ssr  300G  4.8G  296G   2% /media

备份/boot/
[root@rhel /]# symsr -b /boot/ -d /media/251boot.v2i

备份lvm卷
 
[root@rhel /]#  symsr -b /dev/mapper/VolGroup00-LogVol00 -d /media/251data.v2i

如像上面一样报错，则运输入下面三条命令
[root@rhel /]# rmmod symbdsnap
[root@rhel /]# modprobe symbdsnap
[root@rhel /]# echo 3 > /proc/sys/vm/drop_caches

重试备份lvm卷
[root@rhel /]# symsr -b /dev/mapper/VolGroup00-LogVol00 -d /media/251data.v2i

创建SRD光盘镜像

先挂载cdrom

[root@rhel /]# [root@rhel /]# mkdir /media/cdrom
[root@rhel /]# mount /dev/cdrom /media/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only

再创建ISO

[root@rhel /]# createSRD -i /media/cdrom/ -d /media/251SRD.iso -t RHEL5
Creating SRD...Please Wait

Done.
[root@rhel /]#

恢复LINUX系统
用SRD光盘引导，配置好IP，选择不挂载硬盘（一定要）

1.挂CIFS
# mount -t cifs -o username=administrator,password=dghr@0769 //192.172.11.246/ssr /tmp/

2.查看分区状况，扫描LVM
#symsy -list
#lvm vgscan
#lvm vgchange -ag
#symsy -list

3.恢复boot (也可用df -h查看硬盘分区情况）
#symsr -r /tmp/251boot.v2i -d /dev/hda1

4.恢复LVM卷
#symsr -r /tmp/251data.v2i -d /dev/mapper/VolGroup00-LogVol00
