windows 2008 R2裸机还原报错:system image restore failed 0x80042403

简介:

       在中小企业大部分为了节省开支,用一台DC在服役,但是真实环境是,如果这台DC挂了,你将死的很惨。准备你的电话打爆吧。为了避免这样的情况,进行备份是必须的。备份好了,我们需要在虚拟环境中还原看看,是否可用。

        环境:DC:192.168.3.88

         备份服务器:192.168.3.40

     测试机器:windows xp

    先用windows 2008 server backup裸机备份DC和系统状态,然后在一台裸机上还原。这样以保证DC还原的备份状态。但是今天我却碰到这个问题,正好国外的网站也有人碰到了,顺便贴来跟大家一起分享。

That guild didn't work for me as I as trying to restore Hyper-V IDE disks to VMWARE SCSI disks but was getting the same Bluescreen 7B issue. 

Before relasing this, I tried Server 2008 R2's Windows Server Backup, got the same errros, but once I worked out the drive discrepancy issues, I could do a backup to a network location, and then using a windows 7 x64 recovery disk I made do a bare metal restore to VMWARE by using System Image Recovery on a network drive. Was very happy with this :)

So far I've done this to two servers sucessfully.

Issue:

the method mentioned above is failing on one server, first I get the error:

"The system image restore failed.

 

Error details: The computer needs to be restarted to finish preparing a hard disk for restore. To continue, restart your computer and run the restore again. (0x80042403)"

Now If I try one of the other backups, it just starts restoring. If I restart as recommended I get the error:

"The System image restore failed.

 

No disk that can be used for recovering the system disk can be found."

it has a details option, that mentions USB drivers, DISKPART, etc, but none appear to be releviant.

Now I've tried backing up to different network locations, ensured that backups are sucessful on the server, trying larger virtual disks but same errors every time.

The server that is failing is Server 2008 R2, with SQL 2008, on a single disk (not best pratice, but this is just a POC box to run a small DB).

All 3 servers have been given identical configurations under Hyper-V and VMWARE.

Question:

So if it works for my other servers why won't it work for this one?

Is is something to do with SQL that's causing it to happen? (wouldn't think so).

Any suggestions on what else I could try?

I know I could just backup the databases and build a new one, but I'm liking this backup method, and if I wanted to use it under a full production senerio I'd like to know how to resolve the error should it arrise.

 

答案:

I have your answer: shrink the source partitions.  See here for a guide with details: Windows 7 System Image Disc Recovery

If your destination disk has a lower capacity than the source disk, you need to go into the disk manager and shrink each partition on the source disk before restoring.

Example: Source is a 500GB hard drive with only 100GB of data, but destination is a 300GB hard drive. You will need to shrink the source partitions to 1GB less than maximum (100 + 1GB) before restoring.

  总结:就是我们的原始DC的磁盘有多大,目标裸机一定要大于或者等于原来DC的容量大小。也就是说DC以前有100G,那裸机的DC一定要大于或者等于100G。
