You can navigate to a subfolder by double-clicking a folder or pressing the enter key. You can also navigate to the desired folder by typing the path e.
This is important to remember -- the shadow copy feature does not replace file backup procedures. Instead, shadow copy should be considered a supplement to regular file backups. It should be used as a last-resort recovery method. The Windows shadow copy feature will create a new shadow version of a file whenever a restore point is created by the operating system. In our example, we have only one shadow copy, but under normal operating circumstances, there will often be several shadow copies to choose from.
Just keep in mind that the further back in time you go for your restoration copy, the more data you are likely to lose. Mark W. Kaelin has been writing and editing stories about the IT industry, gadgets, finance, accounting, and tech-life for more than 25 years.

Recovered all the free space… Thanks a bundled…. Out of I changed it from I have deleted all the temporary files, internet temp files, unnecessary hidden files. I have even finished the disc clean up for the C drive.
Dude, you're a life saver. I was in the red zone 3gb left and searched for an answer for 2 days. You freed up 24GB of free space on my 3 month old GB computer. I read the thing about vssadmin and tried the command but nothing was displayed not even shadow copy, I'm struggling with this since the last 3 months, my laptop is Acer Aspite please i need help, since 3 months my disk space has been by 23 GB!
Hi, when ever i type the command "vssadmin list shadowstorage" and enter. Kimboa, its been a while since I have used Vista, but you should be able to right click the icon and select "Run as Administrator". That should help you out. This is an awesome post, thanks for explaining it so well and helping us novices out.
I freed up over 20GB in 5 minutes. I just ran compcln. It took a few seconds and released a life-saving 2GB, all "shadow storage". Thanks for this. My Acer was sold with a stupid 30GB c: drive partition. I've been struggling to keep some spare c: drive space. So 2 billion thanks…. This post was extremely helpful. After reloading Vista I could not figure out where 35gb were at and this post solved the mystery.
I once again have a clean and spacious system! I followed it to the letter, checking all syntax, and still cannot get the command to "take". The error returned is "Invalid option value". As I said, I am very carefully typing the exact syntax and have done it 3 times. Can someone help me????? Bella in your example of the command, make sure you are not adding the hyphen in from front of vssadmin.
Thanks for your help, Mike! I ran through the same process again. This time it did work. The only difference: I also ran the "vssadmin list shadows" command. I hadn't thought it necessary before, silly me. I know this web site gives quality based articles or reviews and other information, is there any othber site which offers these information in quality?
My programmer is trying to convince me to moe to. I have always disliked the idea because of the costs. But he's tryiong none the less.

Thanks again. ONCE again…thankx a lot! Jon With a hard drive of GB, your half way to a terabyte of storage I've built servers with far less storage than what you have available! Hi Dhanur, Good that you came across this topic to see how you were loosing hard disk space. Carla MaxSize is the maximum amount of disk space you want System Restore to use.
Carla See my May 7th comment above for recommendation on setting amount of space. Carla 8. You can always change it later. Thank you very-very much!! I feel so relieved!! The Core. See below: Microsoft Windows [Version 6. Any thoughts. Bill Your observation about Vista associating "My Documents" folder to the "Documents" folder is correct and the reason why is because My Documents is a junction point. Hope this helps! On my D: recovery? Is this ness?
This can occur in the software or in the hardware. The Windows operating system includes a VSS provider that uses copy-on-write. A hardware provider offloads the task of creating and maintaining a shadow copy from the host operating system.
The following diagram illustrates how the VSS service coordinates with requesters, writers, and providers to create a shadow copy of a volume. This section puts the various roles of the requester, writer, and provider into context by listing the steps that need to be taken to create a shadow copy.
The following diagram shows how the Volume Shadow Copy Service controls the overall coordination of the requester, writer, and provider. The requester asks the Volume Shadow Copy Service to enumerate the writers, gather the writer metadata, and prepare for shadow copy creation. Each writer creates an XML description of the components and data stores that need to be backed up and provides it to the Volume Shadow Copy Service. The writer also defines a restore method, which is used for all components.
The Volume Shadow Copy Service provides the writer's description to the requester, which selects the components that will be backed up. The Volume Shadow Copy Service notifies all the writers to prepare their data for making a shadow copy.
Each writer prepares the data as appropriate, such as completing all open transactions, rolling transaction logs, and flushing caches. When the data is ready to be shadow-copied, the writer notifies the Volume Shadow Copy Service. The application freeze is not allowed to take longer than 60 seconds. The Volume Shadow Copy Service flushes the file system buffers and then freezes the file system, which ensures that the file system metadata is recorded correctly and the data to be shadow-copied is written in a consistent order.
The Volume Shadow Copy Service tells the provider to create the shadow copy. At this point applications are free to resume writing data to the disk that is being shadow-copied. The shadow copy creation can be aborted if the writers are kept in the freeze state for longer than 60 seconds or if the providers take longer than 10 seconds to commit the shadow copy.
The requester can retry the process go back to step 1 or notify the administrator to retry at a later time. If the shadow copy is successfully created, the Volume Shadow Copy Service returns the location information for the shadow copy to the requester.
In some cases, the shadow copy can be temporarily made available as a read-write volume so that VSS and one or more applications can alter the contents of the shadow copy before the shadow copy is finished.
After VSS and the applications make their alterations, the shadow copy is made read-only. This phase is called Auto-recovery, and it is used to undo any file-system or application transactions on the shadow copy volume that were not completed before the shadow copy was created.
A hardware or software shadow copy provider uses one of the following methods for creating a shadow copy:. Complete copy This method makes a complete copy called a "full copy" or "clone" of the original volume at a given point in time. This copy is read-only. Copy-on-write This method does not copy the original volume. Redirect-on-write This method does not copy the original volume, and it does not make any changes to the original volume after a given point in time.
Instead, it makes a differential copy by redirecting all changes to a different volume. After the mirror connection is broken, the original volume and the shadow copy volume are independent. The shadow copy storage area can be on the same volume or a different volume.
This preserves a copy of the data block on the original volume before the change overwrites it. The copy-on-write method is a quick method for creating a shadow copy, because it copies only data that is changed. The copied blocks in the diff area can be combined with the changed data on the original volume to restore the volume to its state before any of the changes were made.
If there are many changes, the copy-on-write method can become expensive. Instead, the change is written to another volume's shadow copy storage area. Like the copy-on-write method, the redirect-on-write method is a quick method for creating a shadow copy, because it copies only changes to the data. The copied blocks in the diff area can be combined with the unchanged data on the original volume to create a complete, up-to-date copy of the data.
There are two types of shadow copy providers: hardware-based providers and software-based providers. There is also a system provider, which is a software provider that is built in to the Windows operating system. Hardware-based shadow copy providers act as an interface between the Volume Shadow Copy Service and the hardware level by working in conjunction with a hardware storage adapter or controller.
The work of creating and maintaining the shadow copy is performed by the storage array. Hardware providers always take the shadow copy of an entire LUN, but the Volume Shadow Copy Service only exposes the shadow copy of the volume or volumes that were requested.
