Fix: volsnap event ID error on Windows computers

If yous are receiving a volsnap issue ID mistake on Windows 11 or Windows 10, and so this post will help you resolve the problem. The listing of event id includes 36, eight, 25, ix, 33, ane, 24, 35, 28, 23, 14, xvi, etc in Windows 11/ten Event Viewer. Before you brainstorm, ensure you have an administrator account.

What is Volsnap?

Volsnap or Volsnap.sys or Book Snapshot is a Windows system file that is related to the Volume Shadow Copy service. VolSnap. Technically it's a Windows driver that helps the OS uses the Volume Shadow Copy and has admission to core files, hardware, etc. VSS is activated whenever at that place is a backup restore operation, data mining, disk to disk backups, etc.

Fix volsnap event ID error on Windows computers

Here is the list of event IDs followed by reason and solutions.

1. volsnap Event ID i
2. volsnap Issue ID eight
3. volsnap Event ID nine
4. volsnap Effect ID fourteen & Consequence ID 16
5. volsnap Event ID 23
6. volsnap Outcome ID 24 & 35
7. volsnap Event ID 25
8. volsnap Event ID 28
9. volsnap Event ID 33
10. volsnap Upshot ID 36

You will need an admin business relationship to execute the suggested steps.

one] volsnap Event ID 1

VSS creates a buffer surface area called Diff Expanse which is used to temporarily write files when the data is moved. This buffer is dynamic and VSS tin increase when required. However, when the shadow re-create of book could not create a different area file on volume, y'all get volsnap Event ID 1 in the logs.

The only solution is to move the Unequal Area to a different volume. You can configure the Diff Area so that it is stored on a dissimilar volume and ensure it is in NTFS format. Ensure to choose to specify No Limit or at least 15% of the bulldoze's size or another drive.

Notation: When the location of the Diff area is changed, all previous shadow copies are deleted

To configure the shadow copies or the Unequal expanse, you need to go to My Computer > Manage > Right-click on whatever volume and select Configure Shadow Copies. You can gear up the unequal area to a different volume by selecting a book from the drop-downwardly list under the Storage expanse, and and then relieve the changes.  Cheque out the official certificate for complete details.

2] volsnap Upshot ID 8

It is related to Book Snapshot Driver Integrity. If the process times out during the procedure, and the side by side one begins, it will result in this fault. To resolve this, y'all need to schedule shadow copies for a different time. So if VSS reattempts, it has enough time to complete it.

three] volsnap Event ID ix

It occurs when the VSS driver doesn't have plenty resource to perform operations. It can be considering of low memory or CPU or loftier disk I/O load.

To resolve this, notice out what is taking all the resources, and remove them. You can also choose to run VSS at off-timings and ensure that Unequal Surface area is allocated to a defended volume instead of on the same disk.

iv] volsnap Event ID sixteen & Event ID xiv

Event ID 16 occurs when the storage which stores VSS is forced dismounted. In the case of Event ID 14, the operation is aborted because of an IO failure.

There is no direct solution, merely since these are deejay errors, admins can further look into the deejay or NTFS events to observe what is causing the failure. If needed, the deejay can be replaced.

5] volsnap Event ID 23

This is some other case where in that location was insufficient disk space on the volume to create the shadow copy of the book. The but manner out is to motion the Diff Area to a volume with more than storage capacity or dedicate an NTFS book to it.

six] volsnap Issue ID 24 & volsnap Event ID 35

The event is triggered when in that location is bereft disk space on the VSS book. If the shadow copy is unable to abound, then this will abort the functioning equally it tin can further lead to the deletion of older copies. The solution is the same every bit others that you need to increment the space of VSS and Diff expanse. Once washed, run the fill-in again.

7] volsnap Upshot ID 25

It's triggered when the load on the IO is very loftier or the shadow copy storage is existence copied. In simple words when there is a backup going on, and some other backup gets triggered trying to backup the fill-in, this increases the load and results in failure.

Since the IO load is high It admins need to codify a strategy where the backup schedules are spanned across the fourth dimension to ensure in that location is no clash.  According to Microsoft, yous can run the following commands on the host car to place the shadow copy on another deejay:

vssadmin add shadowstorage /For=<driveletter> /On=<destinationdriveletter> /MaxSize=UNBOUNDED vssadmin resize shadowstorage /For=<driveletter> /On=<destinationdriveletter> /MaxSize=UNBOUNDED

Brand sure to increase the amount of RAM and resources.

8] volsnap Effect ID 28

It occurs because of a problem with non-paged pool allocation. There is a hotfix available from Microsoft. Brand sure to use it.

nine] volsnap Issue ID 33

This is logged when the process removes the oldest shadow copy of volume to keep disk infinite usage for shadow copies of a book. Information technology works according to the user-defined limit.

To resolve the trouble you can either increase the space allocated for VSS or allocate a separate volume then the backup doesn't run out of infinite.

nine] volsnap Event ID 36

When the VSS is not able to abound the shadow copy storage considering of the applied limit, it triggers the mistake. To resolve this error you can run the following commands to aggrandize the ShadowStorage; drive messages need to be changed appropriately:

Almost of the volsnap Event IDs are related to storage infinite, overlapping backup, and depression resource.

Where did volsnap shadow copies disappear?

In instance you are missing the older copies, it means, they are have been removed and new copies accept been placed. It usually happens when space allotted to VSS is limited, and the process needs to create space. Like to any fill-in process, it will delete the oldest copy.

How exercise I turn off Volsnap?

You need to disable or turn off the Book Shadow Service. Withal, this will bear on some related services such every bit Arrangement Restore and Backup services. On a service, practice not allocate any space for VSS and you are through.
