ISSUE: MS Exchange database backup "[VSSDatabaseExpt] ¢SS_E_UNEXPECTED_PROVIDER_ERROR"

Article ID: 8071
Reviewed: 90/04/2020

Product Version:
AhsayOBM: 7.3.0.0 or above
OS: Windows

Problem Description

When performing either a scheduled or manual MS Exchange database backup job. The following backup error is received in the backup report:

No. Type Timestamp Log
* info ... Using Temporary Directory ...
* erro YYYY/MM/DD hh:mm:ss Cannot start shadow copy, reason =¢SS_E_UNEXPECTED_PROVIDER_ERROR
* ... ... ...
* erro YYYY/MM/DD hh:mm:ss [VSSDatabaseExpt] ¢SS_E_UNEXPECTED_PROVIDER_ERROR
The backup error persists even after the following actions have been performed.

  1. The MS Exchange version is updated to the latest service pack / rollup
  2. The MS Exchange Server has been rebooted
  3. The VSS writers has been re-registered using the %OBM_INSTALL_PATH%\bin\RegisterVSS.bat
Checking the status of the VSS writers using the vssadmin list writers command shows the 'Microsoft Exchange Writer' is still in a "Failed" state.

Example: 

C:\Users\Administrator>vssadmin list writers
vssadmin 1.1 -Volume Shadow Copy Service administrative command-line tool

Cause

This is Microsoft Volume Shadow Copy (VSS) service error, as there is not enough space on the MS Exchange server to create a shadow copy because the maximum size of the shadow storage area is too small.

Resolution

To resolve this issue, consider resizing the shadow storage area on the MS Exchange server.

Please refer to the Microsoft Documentation for details on how to resize the shadow storage area
