What is Volume Shadow Copy in Windows 10?
Available in Windows 10/8/7, Volume Shadow Copy is a feature that creates snapshots (shadow copies) of disk volumes, even when they are in use. You can create or store shadow copies on local disk, external hard drive or network drive.
Shadow Copy requires the NTFS file system to create and save shadow copies. Therefore, Windows Backup and Restore that use Shadow Copy technology can only protect volumes formatted with NTFS.
You probably have more shadow copies than you know. Every time a system restore point is created, you will have a valid shadow copy. When your Windows 10 system does not work as it should, you can use system restore point to restore Windows 10 to previous version.
As mentioned, Shadow Copy maintains snapshots of the entire volumes, so you can also use shadow copies to recover deleted files besides restoring system. By default, System Protection is turned on for system drive (C: drive). You can manually use it to protect other volumes besides C: drive.
How to use shadow copy to restore lost files?
If you have shadow copies available on the drive on which the lost files were previous located, then you can easily use the Previous Versions to restore deleted files. For example, to restore some files that were saved on Desktop, you can try the following steps:
1. Locate the Desktop folder in File Explorer.
2. Right click on the Desktop folder and select Properties.
3. Navigate to Previous Versions tab, and then select the right version you want to restore and select Restore.
• If you cannot find the folder containing the lost files, you can find its parent folder and then restore it to the previous version.
• If you forget where the deleted files located, then you can download the free tool Shadow Explorer to help you many shadow copies in a very convenient way.
How to delete shadow copies?
By default, Windows 10 allows you to take 5% of the volume space to store shadow copies. If you think the shadow copies have taken too much disk space, then you can delete all shadow copies or delete all but the latest one.
To delete all shadow copies:
1. Right click on This PC, then select Properties and System Protection. Or you can directly go to Control Panel > System and Security > System, then tap on System Protection in the System Properties window.
2. Click Configure.
3. In a new pop-up window, click Delete to delete all shadow copies.
It is recommended to delete all but the most recent shadow copies. To only save the most recent shadow copy, you can use the built-in utility Disk Cleanup.
Can volume shadow copy replace backups?
Windows 10 shadow copy cannot replace backup for a couple of reasons.
1. The shadow copies are stored in the original volume, so if the volume crashes, no shadow copies are available.
2. Shadow copies may not be created regularly by the default settings.
3. Your valuable shadow copies may be deleted without warning you when disk space is low.
4. Shadow copies may not correctly record all the files changes.
Therefore, if you want your system and data to be safe, you should create actual image backups besides shadow copies.
