Problem with restore points

At intervals of between about 2 weeks and a month, I get an Event Log Error 25 (Volsnap) indicating that my restore points for my boot drive have been deleted and that I need to make more space available or to consider reducing IO load on the drive.  There is plenty of space, and the error occurs at reboot, so there is no way to reduce the IO load.  The drive is an SSD and all diagnostic indicate that everything is fine.  The fact that it occurs at reboot at random times means one likely time is after a significant OS update, which is the time one would most likely need to do a system restore.  I am running windows 8.1 with all updates applied.

Any ideas?

Thank you

More material evidence is needed. There should not be more than 85% of disc capacity occupied according to "rule of thumb". I cannot imagine "all diagnostics indicate.." when there is(are) log error(s). Perhaps some history of update, installation and change of configuration may allow some detailed insight into the origin of your problem.

The disk has about 75% free space. (375GB free on 512GB disk) There were about 2GB in use by restore points and a max of 33GB allocated.  Crystal Disk Info shows no problems or warnings and 99% lifetime remaining.  There are no errors or warnings in the event log related to disks at the time of reboot.  The only disk message for the boot drive was the normal info message that comes up on every boot for every disk "  Volume C: (\Device\HarddiskVolume7) is healthy.  No action is needed."

There seems to be no pattern.  The machine is sometimes rebooted.  (as needed plus once per week scheduled).  It usually works fine, but occasionally, the reboot seems to take a long time and I see the disk activity flash for a long time as, I assume, the restore points are being deleted.

Hi rak299,

If you continue to receive event ID 25, follow these steps to resolve the issue:

a. Put the shadow copy storage on another volume, even if the volume is located on the same hard disk.

b. Make sure that the volume that causes event ID 25 is not the same volume that contains the paging file. If the volume that causes event ID 25 contains the paging file, consider putting the paging file on another volume.

c. Make sure that the volume that causes event ID 25 is not used as the shadow copy storage for any other volume.

You can use VSSADMIN to resize the shadow storage location and size:

Method 1)

Run "vssadmin resize shadowstorage /for=c: /on=d: /maxsize=2500mb"

This will set Partition D: for Storage area for Partition C: with size limit of 2500mb (This valve will vary according to your requirement)

Method 2)

Run "vssadmin delete shadowStorage /for=C: /on=C:"

Run "vssadmin add shadowstorage /for=C: /on=D: /maxsize=2500mb"

Vssadmin resize shadowstorage

Note: Resizing the storage association may cause shadow copies to disappear.

I like the idea, but none of the syntaxes in the article or in your reply work with windows 8.1

Testing of the vssadmin in the administrative command prompt appears to function correctly on my Windows 8.1 version 6.1 build 9600. The Technet link provided states that it should also work for Windows 8.

It looks to me like the "add" function to put shadow storage on a different volume does NOT work. When I run "vssadmin add shadowstorage /for=C: /on=D: /maxsize=2500mb" in an administrative command prompt, the response is "invalid command".  It then lists valid syntax including several list functions and a delete.
