A related question if someone can answer. Restoring from full image backup would restore even the user data and files to that previous date. Or is there a way to restore ONLY the programs and settings?

More specifically, is there a way to somehow backup the windows updates (and even the MS Office updates) so that when we reinstall it from the recovery DVD (factory fresh image) we do not have to download the hefty updates again?

If yes, does the method involve downloading all the updates again or the already downloaded updates can be used?

The short answer is: not really. A backup is just a backup of files on you disk. It doesn't "know" while files are system files, which files are parts of updates, and which files are your data - it's all just files. So a restore is either complete (all files) or partial (you choose which files and folders to restore). Updates are also frequently invasive, meaning that they touch things you wouldn't expect to be touched. There's simply no way to keep it all straight.

The solution many people take is when building out a new machine is to first install everything. Get it all up to date, and then take a full backup snapshot of the machine at that point in time. That way they have a known good image that they can revert to, and would have to take only updates released since that point if they need to revert to it.

The ONE thing that I don't really like about Vista is the inability to decide how many restore points/memory is used (as I could in XP). Every week, I run maintenance, and when I run disk cleanup, there are at least 5 gb of restore points saved. Waste of disk space.

Leo, Does Restore (XP) roll back Windows updates? I have a problem with a program that suddenly developed unusual behaviour after a packet of Windows updates was installed. I want to Restore to a date prior to the Windows update to test program behaviour. And if the problem goes away, I will re-install each of the updates testing for the "baddie". Will this work?

I believe it will.

You can uninstall MS updates from the Add/Remove programs area. You probably will have to put a check in a box at the top to display them.

The best registry backups are made by the free ERUNT progam. Works with Vista and XP. I put this on every customer's computer. Do some googling. Packrat1947

Thanks RonH. Yes, I was looking to use Add/Remove programs but I could not identify the kbxxx updates that were loaded at the time the problem began. When I selected Update History from Windows Update, the only thing listed was Microsoft Update download (!!!!) and looking in C:\Windows listed about 10 kb's. I decided to first test my theory of the problem being caused by an update, by Restoring to an earlier date (which I assumed would roll back those updates). The time it would take to uninstall each likely kb, then reinstall the program, would be wasted if an update was not my problem.
So I would still like to know if Restore does roll back Windows updates. Leo???
Thanks, Bevin.

Dear Leo,

This is do with back-ups. I have some difficulty with finding my current active files which must be miniscule compared with your gargantuan back-up base. Can you please give some tips on your 'filing' system as regards finding specific files in the mass of those that must accrue from your nightly back-up ?

Thank you

Actually has very little to do with the backups, per se. The backups are simply images of my hard drive, so they're organized the same way things are laid out on my harddrive.

As for how I lay things out on my hard drive ... well, that's been a long evolution over many years as my needs have changed, and likely wouldn't apply to you. Best advice I can offer it to plan a hard drive organization that makes sense to you, and then the backups shoudl follow.

I am slightly confused regarding the statement that "System Restore does not backup your data". If I inspect my shadows in the shadowstorage (e.g. with Shadow Explorer) I can see all my files that existed at the time the shadow was written and I can even reimport them. The same goes for system files. How does that relate to your statement that I quoted above? Thanks in advance for your answer. WHS

That's a Vista-only feature. Technically I'm not sure it's part of System Restore. Even if it is, it's not a backup. Consider what happens if your hard drive dies - your shadow storage dies too.

Hi Leo, thanks for the answer. You are right in the sense that a true backup must be to another media. That's why I use Norton Ghost PLUS a very handy Maxtor One Touch disk that I leave disconnected. However, as long as the HDD stays alive (and that is the base case for most folks), it is possible to recover files and folders from the shadows in shadowstorage. And that has come in handy in several instances - especially if they are system files.

Hello Leo,

I heard that having System Restore on could be a security issue. Is this true?

Thank you

Not that I've heard of. Only thing I can think of is using it to restore something you thought you had removed.

I'd like to ad one point: be aware about making a system backup image...it's best to FIRST run all your "anti" software to get rid of all the viruses and malware you have. Otherwise, if you end up having to use the backup image, you're going to have all the junk you had before you started.
