In the new window, tick Turn on system protection and click Apply to enable. If you want to customize volume shadow copy in Windows 10 with a specific time, you could use Task Scheduler. The steps are below. Open Task Scheduler.
You can click Start , type task scheduler and select it from the list. Click Create Task and then specify a name for the task eg: ShadowCopy. Step 3. Create a new trigger. You can click the Triggers tab and New Step 4. Enable shadow copy. You can click the Actions tab and New When you run program items using VSS technology, you may receive volume shadow copy error in Windows In this case, you should go to Services and check if the Volume Shadow Copy service is started at first time. Once it stops, the volume shadow copy service is not working in Windows 10 and the program will fail to create a snapshot for your volume.
Navigate to the file or folder you want to restore in a previous state and right-click it, then select Restore Previous Versions from the drop-down menu. In addition, you still can select Properties and click the Previous Versions tab. In this window, you can see 3 options, including Open , Copy , Restore. Tip on there are no previous versions available issue : One of the possible reasons why you receive this error is that the volume shadow service is disabled.
You can manually enable it in task manager by the following steps. Download ShadowExplorer utility, install and launch it. 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.
A hardware-based shadow copy provider makes use of the Volume Shadow Copy Service functionality that defines the point in time, allows data synchronization, manages the shadow copy, and provides a common interface with backup applications. However, the Volume Shadow Copy Service does not specify the underlying mechanism by which the hardware-based provider produces and maintains shadow copies. These providers are implemented as a user-mode DLL component and at least one kernel-mode device driver, typically a storage filter driver.
Unlike hardware-based providers, software-based providers create shadow copies at the software level, not the hardware level. A software-based shadow copy provider must maintain a "point-in-time" view of a volume by having access to a data set that can be used to re-create volume status before the shadow copy creation time.
An example is the copy-on-write technique of the system provider. However, the Volume Shadow Copy Service places no restrictions on what technique the software-based providers use to create and maintain shadow copies.
A software provider is applicable to a wider range of storage platforms than a hardware-based provider, and it should work with basic disks or logical volumes equally well. A logical volume is a volume that is created by combining free space from two or more disks. In contrast to hardware shadow copies, software providers consume operating system resources to maintain the shadow copy.
One shadow copy provider, the system provider, is supplied in the Windows operating system. Although a default provider is supplied in Windows, other vendors are free to supply implementations that are optimized for their storage hardware and software applications.
To maintain the "point-in-time" view of a volume that is contained in a shadow copy, the system provider uses a copy-on-write technique. Copies of the blocks on volume that have been modified since the beginning of the shadow copy creation are stored in a shadow copy storage area.
The system provider can expose the production volume, which can be written to and read from normally. When the shadow copy is needed, it logically applies the differences to data on the production volume to expose the complete shadow copy.
For the system provider, the shadow copy storage area must be on an NTFS volume. The Windows operating system includes a set of VSS writers that are responsible for enumerating the data that is required by various Windows features. In addition to backing up application data and system state information, shadow copies can be used for a number of purposes, including the following:.
And the copies can be created by any Windows component using this technology on local, external and removable volumes or network locations, such as when creating a scheduled Windows backup or automatic system restore point.
If this service is stopped, all components depending on the service are still not working. In the following paragraphs, we will walk you through some specific errors as well as the solutions in Windows PCs.
Recently we received the feedback saying backing up Windows to a new external hard drive but failed with error message 0x The details are as follows:. A Volume Shadow Copy Service component encountered an unexpected error.
Check the Application event log for more information. In this case, the problem is that the Volume Shadow Copy Service is disabled. Thus, the best solution is to set this service to Automatic. The information is as shown below:. The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur.
Well then, what're the solutions to this problem? Three ways are offered. Step 1: Similarly, you need to enter Services page by inputting msc in the Run window.
Step 4: Enter the Dependencies tab, check the dependency services that are required for Volume Shadows Copy Service to run. Finally, click OK. Also, use the command prompt " chkdsk " to do this work. Free Download. For more information view the event log If you close the property page and try again, this system restore error 0x will appear again.
The amount of disk space used for the shadow copies is not based on the size of the volume, but rather the size and frequency of changes. This is driven by the applications used. For example, if an application only writes changes to the file when data is changed, this uses far less shadow copy space than an application that rewrites the entire file.
When accessing previous states of a share, the ACLs on files and folders still apply. If you did not have access to the file before, you won't have access when viewing it via the Previous Versions client.
The shadow copy file or folder information is stored in the System Volume Information of the volume selected to hold the information and cannot be accessed outside of the shadow copy client. Finally, although the whole content of the volume is protected by VSS, you can only view previous states via share properties.
If you need to recover a file that is not within a current share, create a new share that contains the file and then connect to the share. Notice that if you create a new share, you see a full history of all previous versions equivalent to existing shares. This happens because VSS logs the entire file system, not just existing shares. You can enable VSS for a drive or volume with the following steps.
