What’s the difference between a System Image and a regular backup in Windows 7?

Q: I want to mirror my hard drive on an external hard drive. On page 237 of Windows 7 For Dummies, your book says “the  [Backup and Restore] program also creates a system image – an exact copy of the drive Windows 7 lives on.” Is this what I want?

A: Windows 7’s Backup and Restore program offers several options, including one to “Create a System Image.”

System Image

Meant for foolproof backups, a System Image creates an exact copy of your entire Windows 7 hard drive and packs it into one large file, which you can store on a second hard drive. (A portable hard drive works very well for this and other tasks.)

A System Image provides a perfect backup for most people, as it contains everything on their C drive: Windows 7, all your installed programs, and all the files created with those programs. Plus, it contains all your program settings. If your hard drive dies, you can install your System Image on your new hard drive, and be back up to speed quickly and easily.

So, how does a System Image differ from the Backup and Restore program’s regular backup?

Regular Backup

A regular backup copies your files, mostly from Windows 7’s Libraries:  Documents, Music, Pictures and Videos. It’s meant for restoring items on a small scale: If you accidentally erase a file or two, turn to your regular backup to cherry pick the lost files you want to restore.

A System Image, by contrast, copies the entire drive. Restoring it is an all-or-nothing affair: You can return to the exact setup you had when you made the system image — but you can’t grab that file you accidentally deleted from your Documents library.

That’s why System Image provides a near perfect backup. When your hard drive eventually dies, you can restore your data from your System Image file: You boot from your Win 7 installation DVD (or a System Repair disc, which you can create when making the System Image), and choose a menu option to restore your hard drive from a System Image file.

Your computer grabs the System Image, places it onto your replacement hard drive, and you can begin working again from the time and date that you made that System Image backup.

When you have a System Image, you won’t need to reinstall Windows 7, your programs, or your data files: It’s all there. You won’t even need to reactivate Windows, or mess with those annoying product keys.

It’s worth creating a System Image at least once a week, as every hard drive will eventually die. Creating a System Image ensures your work won’t die along with it. And, if your computer came with Windows 7 pre-installed, create a System Repair Disc along with it — you rarely, if ever, receive a Windows 7 installation DVD when Windows 7 comes pre-installed.


Since writing this, a few more helpful details have surfaced:

  • If you have more than one version of Windows installed on your computer, say, Windows 7 on one partition, and Windows Vista on a second partition — the System Image will copy both versions of Windows, bringing them both back to life if you need them.
  • The Backup and Restore program creates the System Image in the root of your portable hard drive, using the folder name WindowsImageBackup. If you create another System Image, it overwrites the first. To preserve a particularly coveted System Image from being overwritten, change the System Image folder’s name from WindowsImageBackup to WindowsImageBackup_Save or something similar. Later, to restore from that particular System Image, change the folder’s name back to WindowsImageBackup. (Thanks, Bob!)
  • The hard drive containing the System Image must be formatted with NTFS, not FAT. Fortunately, it’s fairly easy to format a hard drive using NTFS.
  • Windows 7 can’t create a System Image on a flash drive. If you want a System Image on a flash drive, you need to create it manually someplace else, and then copy it to your flash drive.

I created a window 7 recovery disk at the start of our new computer w wind7 as os.
Do I still need a system image backup?
If i want to b/u websites selected as favourites in both the admin. a/c and user a/c’s do I need system image b/u or is some way of b/u of favourite lists on a cd.
Thanks for your help

Hashim, the System Recovery disk you made will only return your PC to the state it was in when purchased. It won’t contain your data, just Windows 7 and all the programs bundled with your PC.

You still need a system image backup, described on this page, if you want a complete copy of your hard drive, including your installed copy of Windows, your installed programs, and all of the data from everybody’s user accounts.

If you only want to backup web sites selected as Internet Explorer Favorites in every User Account, then log on with an Administrator account and use Windows 7’s built-in Backup and Restore program. From there, you can select the Favorites of every user account holder and choose to have them backed up to a CD.

So creating a backup with System Image takes back up with the last system image and all the file folders or it creates a new system image ? Also, which option is better creating a system image and then using windows back up option(backing up system image) or creating system image every week

Comment from Andy Rathbone
Time November 24, 2010 at 7:49 pm

Garima, when you create a backup using Windows 7’s Backup and Restore program, it creates a backup of the files and folders, *and* a system image. So, the program requires a lot of space for your backup, but it gives you both types of coverage.

I run Backup and Restore each evening, so it creates backups of the files and folders in my Windows 7 libraries, as well as a system image.

To make sure I have enough room, I’ve installed a very large hard drive in the computer that’s receiving the backup.

You can find very large hard drives very inexpensively right now. And, you can install it into an enclosure to make a portable hard drive for backup, as well.

Katrick, you can restore the System Image any number of times on any number of hard disks.

Keep in mind that System Image is a way to back up a single computer. It’s not a way to “clone” a working copy of Windows 7 and install it on several other computers, or it will run afoul of Microsoft’s Activation technology.

Frances, you can create the System image on several DVD-RWs or an external hard drive. It’s much faster and easier to use an external hard drive, however, so I recommend that option.

DVDs are also more prone to burning errors; combine that with their susceptibility to scratches, and they’re much more prone to problems than external hard drives.

Had a Win7 Pro (64-bit) crash and have seemingly put Humpty back together again (maybe). So I made a system image backup to my external USB drive. It overwrote one I had made previously. My question is, can we make more than one system image backups to the same external drive (it is not partitioned) to preserve a “last known good” in the event a new system image backup contains a bad Registry, malware, or whatever?

Comment from Andy Rathbone
Time March 18, 2011 at 12:56 pm

Bob, I’ve never tried to create more than one system image from the same computer onto a hard drive. I’d guess you can do it, as long as you place each system image into its own folder. That should keep them from overwriting each other. (Your hard drive also needs enough storage space, of course.) Let me know if creating the system images in their own folders works for you, and I’ll update this page. Thanks!

Comment from Bob
Time March 18, 2011 at 7:15 pm

Thanks Andy. Well the consensus in various discussion forums I looked through is you need to rename the WindowsImageBackup folder, eg, WindowsImageBackup1 or WindowsImageBackupGood, etc. and the next time your make a image backup, the WindowsImageBackup folder will be created. It does seem to me that it otherwise gets overwritten.

Then should you need to restore, you can pick which one you want, rename the existing WindowsImageBackup to whatever, rename WindowsImageBackupGood to WindowsImageBackup and restore. 🙂

A bit of a shuffle but it works. I had a nasty Win7 crash installing IE 9 64-bit, black screen, no Windows, finally put Humpty back together and ‘thought’ I was ok, so I made a system image backup. It overwrote the one I made not long before that I ‘knew’ as ok. The black screen returned and restoring didn’t help since I was restoring a bad system. Corrupted Registry, found the problem, fixed it and I was back on easy street. Had I had my original good system image backup to fall back on, that would have spared me some hours.

P.S. I was told/read that you can’t designate a particular folder for the system image backup. The program makes the system image backup in the root of the drive, hence the folder-renaming shuffle because Restore is going to look for the WindowsImageBackup folder in the drive’s root.

Thanks for the article Andy and the info on the way to keep multiple system image backups on one external backup disk.
How I structure my backups for WinXP was to have three external backup disks each large enough to store at least 3 WinXP .bkf files. That gives me 9 “image” backups ie. just over a week’s worth which is my timeframe for detecting any stuffups that might need recovering. Each night the next disk in sequence gets used for a backup. Having three disks means that if one disk attached during a backup fails I have two secondary ones. One of the two “non-attached” backup disks gets taken “offsite” each night leaving me at any given momement with one attached doing a backup, one onsite for immediate recovery and one offsite in case the office burns down 🙁
So with Win7 I wanted to replicate the same idea of having at least 3 backup disks each holding at least 3 images (or more if I need a longer holding time before I overwrite/recycle the oldest). What I have so far done is renamed my first backup directory from WindowsImageBackup to

What I next intend to do is to restore one of the older images with the renamed directory onto a second identical laptop which should effectively restore the second laptop to a point in time backup of the first laptop.
Lets see if it works…

I have been saving individual files to portable hard drive for years. It’s kind of hard to get the one download which contains your entire system. It sounds really great, but I agree with you, it’s a good idea to restore the System Image, rather than have to search for (or miss) certain files. Great if a person wants several computers to run off the same image that you have set up (I assume it will let you copy as opposed to reinstall and delete original?).
Can you email a System Image to your home address or other user via email?. For safe keeping? Have looked, but can’t find anything about this. Thanks

Hi Andy, I recently bought a Gateway netbook with 64-bit Win7 and am interested in some type of “backup” but I don’t know which. In the past, I have had no qualms about doing a complete system restore to factory settings if I had a problem with my computer. I personally do not have any files, pictures, music, documents or the like saved to my computer that I care about. What I am interested in is making a disc that will include all the “Windows updates” that I’ve spent hours downloading and installing. As you know, the return to factory setting option I’ve been using necessitates doing all the update downloads and installs again. How do I avoid this? Thanks.

Kevin, a System Image backup is exactly what you need, as it backs up Windows, including all the patches and updates you’ve installed up to that moment in time. The System Image will also contain your files, music, and documents, but since you don’t have any of those, your System Image will be that much smaller, faster to create, and easier to store.

I’d plug in an external backup drive to your netbook to back up the System Image, then leave the drive at your house or office for safekeeping.

Ken, you can use a system image to recover from a hard drive that’s currently infected with a virus. However, your system image needs to have been made before the virus infected the drive.

Unless your System Image took place before the infection, you’ll simply be resurrecting the virus along with the drive’s contents.

Michael, yes, you will be able to use your System Image on your new computer that has upgraded hardware.

You’ll likely face two challenges when your new computer first wakes up with the newly restored System Image:

First, since your new computer will have different parts, Windows 7 will begin searching for new drivers for those parts. Windows Update might find them automatically; if it doesn’t, you’ll have to search for the drivers manually.

Second, since your new computer will wake up with a system image that was activated on a different computer, you’ll probably have to call Microsoft, explain the situation, and get a new activation code to enter into the computer. (If your new computer fails the activation test, you’ll see the phone number on the screen.)

Let me know if you encounter any other unexpected problems.

Rich, Microsoft’s System Image Help page says you can only save the System Image to a hard drive:

However, some people on websites report being able to save system images to a DVD. My guess is they had a very small hard drive that could fit onto a single DVD.

So, my guess is that your hard drive is too large to be stored onto a DVD, which is why you’re encountering that error message.

Sam, creating a System Image usually takes longer than a regular backup. The amount of time depends on your drive’s speed and the amount of data.

Plan on the System Image consuming at least one minute per gigabyte. A 100 GB hard drive, for example, would take almost two hours.

Since they’re time consuming, most people set them up to be performed automatically while they sleep.

Sharmil – Yes, making a System Image creates an image of your OS and programs, as well as any personal files on that partition. You can then use the System Image to replicate that same OS and apps (and personal files) onto the same or another PC. If you replicate that image onto another PC, however, you’ll have to deal with Microsoft’s activation process.

Comment from Andy Rathbone
Time February 6, 2012 at 11:12 pm

Adil: The System Image backs up and restores partitions, not the entire drive. So, if Windows crashes, your System Image of the C: partition will restore your Windows partition, and leave your drive’s other partitions intact.

However, you should back up all of your drive’s partitions, because when the hard drive eventually fails, all of your partitions will be gone.

So, if you’ve created several partitions on your hard drive, create a System Image of each of them so you’ll be prepared for hard drive failure.

Thanks for all the wonderful info. I have been confused about a lot of these things for a while. In the past, when needing to reformat I always had to reload the entire set of programs, updates, os, and everything else and it was a major PITA.

I am in the position of having recently just built my first computer, just loaded Windows 7, all the programs, drivers, updates, and it is running fast and so slick. I want to be able to revert back to this point if things get all crudded up somehow, can you point me to the directions for someone in my situation? It sounds like what you’ve explained here is mostly for regular backups, which I should also be doing…but if I allow it to backup weekly or nightly as you do, then my restore point will also not be as fresh and fast as it is today, correct? I see that comment that Bob made, is that my answer to what I’m looking for? Thanks for your clear articles and answers in the comments – so HELPFUL for us all!!!

Comment from Andy Rathbone
Time March 4, 2012 at 1:51 pm

Danny, now that your PC is running exactly the way you want it, create a System Image to save for later. Windows will save that System Image in a folder called “WindowsImageBackup.”

To keep that image from being overwritten, change that folder’s name to “FirstSystemImage” or something similar. That way you’ll always have that System Image to return to.

The next time your computer backs up, it will create a new System Image, recreating the WindowsImageBackup folder to store the new image.

That gives you the best of both: Your original System Image can always restore your PC to when it was newly built and running perfectly. Your other System Image will include all the programs and data you’ve installed since then.

Down the road, when something goes astray, you can choose which System Image meets your needs. If your PC’s really hosed, use your first System Image. If the problem’s minor, then use your newest System Image.

Sune, Microsoft says Windows 7 can’t create a System Image on a flash drive in this table on its web site. However, in the third paragraph, Microsoft says you can manually create a System Image and copy it to a flash drive. That’s an impractical solution, though.

If you want to use a flash drive to store your system image, you’ll have to rely on a third-party backup program.

Hi Andy, thanks for your quick reply (your help in very much appreciated!). This was the first backup I’ve done on my PC, and it’s set up for a monthly backup. As I say, the System Image folder carries the date 15/05/12, and so does the ‘Gary-PC’ folder until I click to restore files. Then, the ‘backup of C’ folder carries the date 09/05/12, which does correspond to a restore point created. It is bang up to date though, as I’ve looked for stuff I know I added to my PC after 09/05/12 and it’s all there, present and correct. Just bugging me! Thanks again – and great books!

I like to revert back to Basic (some problems with Root on dual partition) by reformating it.

Faith – You should be able to create a System Image of a Dynamic disk. I can’t vouch for it personally, as I’ve never tried it. But this post on Microsoft Technet forums implies that it should work.

However, you can’t store a System Image on a Dynamic disk, so be sure to store your image on a Basic disk.

Ross – Yes, you can image the C drive to the data drive. And no, if there’s a virus on the C drive, the data drive shouldn’t be affected. A virus shouldn’t be able to escape from the System Image until the System Image is restored.

Of course, I’ll also do a backup on an external drive but since this laptop is for my son who’s going off to college I thought it would be convenient to backup to the same HD in case the C drive crashes.

Making the backup to the external drive is wise. I don’t advise keeping a system image on another partition of the same drive.

Making System Images is easy, but you should have good faith that a recovery operation succeeds. When I needed a recovery operation, it failed. The WindowSystemImage, which Windows made and which was present on the USB Hard Disk could not be found by Windows and did not appear in the recovery window. The recovery window has no option for browsing, so I had to do a full new installation from scratch.

PiKo: Sorry to hear that your System Image failed. Had you changed the file or folder name of the System Image? Either way, possible recovery failure is one reason I recommend making both a System Image and a regular backup.

Good info, thanks. Will using Windows 7 backup to make both a system image and backup to the same/partition work?

Barb: Yes, you can create the System Image and backup on the same partition. But make sure that partition lives on a different drive than the drive you’re backing up.

Soumya: Yes, if you use a System Image created a year ago, it will return your computer to the state it was a year ago. The personal data you’ve created since that date will be gone. Any programs you’ve installed since that date will be gone, too.

To make the best of a bad situation, head to your C:\Users\YOURNAME\ directory. Then copy your My Documents, My Pictures, My Music and My Videos folders to a portable hard drive.

After you restore your PC using that old System Image, copy those folders back to your C:\Users\YOURNAME\ directory. (Substitute your own user account name for YOURNAME.)

If you’ve been saving your personal data in those main folders, you’ll at least be able to save some of your data.

hi andy,ive just done create system image from drive c,on a 1tb external hd which includes all my data,music photos etc and as prompted to do, a disc for recovery all ok,i then ran the backup and restore facility which you can cherry pick files that you may have lost by accident,but it took forever,after 24 hours it was still on 42% i gave up on it and cancelled,i have backed up my data on another external hd that i did the old way of copy and paste,took me 5 hours maximum,so my data is safe,also it tells me its making another system image that i dont need,what is going on,why so awfully slow,and your sopposed to do this every week,totally impractical,im running widows 7 64bit ultimate,im confused,im doing what my computer is telling me to do,am i missing something,any ideas andy

Trevor: Going back and cherry-picking a few files from a backup shouldn’t take long. Are you seeing the delays when accessing the backup? Or in restoring your cherry-picked files?

My computer automatically creates a System Image and regular backup each night onto a networked drive, and it takes about two or three hours to complete. Cherry-picking a few files takes just a few minutes.

Also, the first regular backup will take a long time, as the computer needs to backup all of your selected files. However, subsequent backups are much faster, as they only backup files that have changed since the first backup.

I’m sorry to hear you’re having problems, but you’re doing the right thing: Finding problems early, before you really need the files.

If Windows 7’s built-in backup is causing problems for you, you might look at some of the third-party solutions out there. Some people prefer them over Windows 7’s backup.

A computer tech friend of mine suggested the use of a remote backup service so I won’t lose necessary data when my hard drive dies. But I am so glad I came across your post coz I learned more things to integrate into my current solution. Your idea on site backup is definitely a bang!

i want to make system image. May i use the DVD for this purpose. Even if i use the dvd then what will be the procedure for working to recover the computer?

Narenda: Microsoft says System Images must be created on a hard drive, not DVDs. You can use DVDs for a regular backup, though, but that will consume a lot of DVDs, as well as a lot of time.

You can use DVDs for a system image… It just takes ages – the wizard prompts you to change disks and what to label each of them. It also verifies each disk…. Unfortunately, I have 150GB to back up (HD is failing and not got an NTFS portable…. the drive with my file back up is FAT32 and has too much to reformat). I am 22 disks in and 19 hours… 5 disks failed (used 27 in total so far) and from the progress bar, I would say 6 or 7 still to go. Obviously, a portable HD is the better option, but hey…. when it’s urgent >.>

Great article! I’m just coming back to PC after 5 years on a Mac with Time Machine for backups (so easy). Andy, my question is what’s the difference between a system image recovery and a system repair disk? Sounds like just having the system image would be the ticket, no?

Justin: Another page explains the difference between a System Image and a System Repair disk. Basically, Windows needs to be running in order to install a System Image. A System Repair disk boots a minimal version of Windows, and then gives you an option to rebuild Windows using a System Image.

In that event, then couldn’t you just use the recovery disk, which sets the unit back to factory and then rebuild using the system image? Seems like one could have either a recovery disk OR a repair disk as long as there is also a relatively current system image to work with?

Justin: Yes, you could use the Recovery Disc. But restoring your computer from the recovery partition takes much, much longer than simply booting from a Repair Disc and choosing the Restore System Image option. Also, when the hard drive eventually dies, so does the recovery partition. A Repair Disc, by contrast, lets you install a System Image onto the replacement drive.

I use Windows 7 Backup and do regular backups as well as creating system images. The odd thing is that my external drive now has less room than you’d think after the backups and two separate system images were created .
It says there is now only 169 GB free of 465 GB total (and 296 GB used) but if I add up the system image directory (two copies, 168 GB total) and the backup (27 GB total) there should only be 195 GB used. I am missing 100 GB of space!
Now I looked at the drive with a defrag program and it shows lots of locked files. Are they part of the system image? And if so, why are they not reported as taking up space (100 GB). Or is my external drive messed up?
Any idea?

Sjaak, have you tried temporarily copying the backups to another drive, reformatting the drive (and making sure the drive has only one partition), and copying the backups back over? It sounds like that drive might have a hidden partition on it that’s taking up the extra space.

You were right, Andy! I reformatted the drive and it’s correct now.
Thanks an awful lot!
