VolSnap Error Shadow Copies Were Deleted On Windows 7

Upon every boot, I get a volsnap error: shadow copies of volume C: were deleted because the shadow copy storage could not grow in time.

And possibility is there that the system restore points are deleted. Coinciding with this issue is the fact that I'm also having problems resuming from sleep.  I'm not sure if the shadow copy error also occurs on resume from sleep

Solution:

I suspect your computer is in Sleep Mode in midnight when backup, if so, the backup won't start.

Try the following method to fix this issue. Note: Please backup the registry before you modify.

1. Click Start, input regedit, press Enter

2. Locate and then click the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VolSnap

3. On the Edit menu, point to New, and then click DWORD value.

4. Type MinDiffAreaFileSize, and then press ENTER.

5. On the Edit menu, click Modify.

6. Type the size that you want for the shadow copy storage area, and then click OK.

Reboot the computer to check if it works.

If it doesn't work, please check the disk.

1. Click the Start, input cmd in the search bar.

2. Right-click cmd, run it as Administrator.

3. Input the command: Chkdsk /f /r

Restart the computer then check if the problem is still there.

If the issue persists, refer this link.

If you have defragment software.  Apparently it may cause the problem. Disabling the automatic defragmentation may solve this issue.

Disable the services related to defragmentation, and you wont come across the volsnap shadow copy deleted error when rebooting.
