Disaster Recovery Plan for complete system restoration

[Guest Roman]

All,

 

I'd like some real-world advice please. I manage a small 5 user

client-server network with a tight budget. The network uses a single server

running Win 2K3 R2. The server has several additional roles including IIS

with WSS3 and a suite of applications running under Terminal Services.

 

I've progressively worked through the precautionary steps including hardware

RAID1 and daily backups using NTbackup to an external USB hard drive.

 

I have an ever present linguring concern about disaster recovery. I've

researched and read numerous tutorials and MS articles however many

real-world forum threads are not so comforting. A real-world thread I read

only days ago highlighted the requirement to ensure all Service Packs and

critical updates are applied to the Windows server installation before

restoring a System State otherwise it will fail. Apparently this information

is not made evident in any articles according to the author. I have spent 3

days attempting a System State restoration once before and I was unsuccessful.

 

I'd like to step through my plan in the hope that I can get some guidance in

what can be improved to increase the likelyhood of success. Apparently 35% of

all system restorations from tape fail according to

http://www.computerperformance.co.uk/w2k3/disaster_recovery_backup.htm.

 

I have scheduled a full system backup, using ntbackup, each morning to

external HD - it only takes 1 hour. I've actually manually selected C:

(SystemData), D: (UserData), and System State because I don't want F:

included because it is the external drive containing the backups. The backups

are appearing on the external drive and I've successfully restored individual

files to test the process.

 

In the event a system restoration is required my plan is:

 

1. If required, replace both RAID1 HDs and partition C: and D: the same size

as they are now,

2. Install the OS,

3. For a full system restoration there is no need to apply Service Packs and

critical updates,

4. No need to run DCpromo,

5. Start ntbackup and start a full system restoration using the Advanced

wizard, and

6. Restart the server and all will be fine :)

 

Now, the way I understand it because I am running a single server and will

be doing a full system restoration, not just System State, I don't need to

follow the authoritative restoration guidelines and repair for AD at bootup?

Most system restores fail because the server administrator never

takes the time to perform a live system restore. It's as simple as

this. Here is what I usually do:

1. I create an image file of the system drive, using Acronis TrueImage.

2. I restore the image file to a spare IDE disk. Disks are cheap!

3. I boot the system with this IDE disk. I now know whether my

methods works or not.

4. I create a new image file twice each year, always keeping the

two most recent versions.

5. I create a new image file before any major upgrade, e.g. before

installing a service pack.

 

If Acronis TrueImage is too expensive for you then you could

create an image disk like this:

- Format a spare IDE disk on some WinXP PC.

- Boot the server with a Bart PE boot CD.

- Use robocopy.exe to copy the system drive to the IDE disk.

Include hidden files & permissions.

 

Creating a Bart PE boot CD (http://www.bootdisk.com) takes a bit

of time but it is a terrific tool for a system administrator.

 

The essential thing in all this is: You MUST test your recovery

process!

As Geoff N. Hiten (SQL MVP) would say:

 

If you don't test your recovery process, you do NOT have a recovery process,

you have a recovery HOPE !!!!

You put it much better than I did!
