Backup of exchange 2016 failing with error V-79-57344-65233

Level 2

Backup of windows exchange server 2016 failed on following error:(Backup exec 20)

Backup- EIS-MXS001.krages.intV-79-57344-65233 - Snapshot Technology: Initialization failure on: "\\\Microsoft Information Store\KRA-DB02". Snapshot technology used: Microsoft Volume Shadow Copy Service (VSS).

Snapshot technology error (0xE000FED1): A failure occurred querying the Writer status. See the job log for details about the error.

Check the Windows Event Viewer for details.

Writer Name: Exchange Server, Writer ID: {76FE1AC4-15F7-4BCD-987E-8E1ACB462FB7}, Last error: The VSS Writer failed, but the operation can be retried (0x800423f3), State: Stable (1).

According to OS admin, exchange server doesn't show any errors.

Exchange server restarted several times and after few successfull backups, error with VSS appears again and backup failed.

In attachment you can find that backup job contains 2 exchange servers.Backup for the first one run properly, but for second server backup always failed. I assumed that backup exec is set correctlly and problem is on exchange server.

How can I find a problem on exchange server?

On the server where you are getting these VSS issues, have you tried to run: vssadmin list writers ? Any writers not stable indicate an issue and it needs to be resolved within Windows. Thanks!
