Ошибка архивации 0x800423f4

Резервное копирование виртуальной машины с SharePoint Server 2019 в  Veeam Backup & Replication v12 выполнялось успешно до тех пор, пока в SharePoint не была настроена и запущена служба поиска Search Service Application. Каждое последующее задание резервного копирования ВМ стало завершаться ошибкой создания контрольной точки Hyper-V production checkpoint следующего вида:

Failed to create VM recovery checkpoint (mode: Veeam application-aware processing) Details: Failed to create VM (ID: ba7b4b0c-3fbd-4c51-8737-2ae39aee005f) recovery checkpoint.

Анализ логов на сервере SharePoint в момент выполнения задания в VBR показал наличие ошибки с кодом Event ID 8194:

   Writer Instance Name: OSearch Replication Service
   Writer Instance ID: {4ce2a6c6-2cf2-4f58-872f-9ce95adf804a}

Попытка создать контрольную точку ВМ вручную в консоли Hyper-V Manager также приводила к ошибке «could not initiate a checkpoint operation: %%2147754996 (0x800423F4)«

При этом в логе Application фиксировалась аналогичная ошибка с кодом 8194.

Команда листинга модулей записи теневого копирования на сервере SharePoint показала ошибочное состояние модуля «OSearch16 VSS Writer«:

vssadmin list writers
...
Writer name: 'OSearch16 VSS Writer'
   Writer Id: {0ff1ce16-0201-0000-0000-000000000000}

   State: [8] Failed
   Last error: Non-retryable error
...

Так как в тексте ошибки в event-логе фигурирует информация о нехватке прав («…0x80070005, Access is denied…»), в первую очередь нужно понять о какой учётной записи идёт речь.

Если посмотреть на стандартные поля в событии об ошибке, то в поле User мы не увидим информации о пользователе:

Однако, если переключиться на отображение подробностей на вкладке Details, то в варианте просмотра Friendly View в разделе с листингом бинарных данных мы сможем увидеть имя учётной записи, в контексте которой возникла шибка:

В нашем случае, это учётная запись фермы SharePoint (Farm account). И в контексте именно этой учётной записи у нас выполняется служба поиска SharePoint. При этом данная учётная запись не имеет полных административных прав на сервере.

Теперь относительного того, куда именно не может получить доступ учётная запись.

При проблемах с резервным копированием службы поиска SharePoint, в качестве одного из моментов, на который стоит обращать внимание, является состояние ключа реестра для службы «Volume Shadow Copy» (VSS):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS

Как минимум, в этом ключе:

1) В под-ключе \VssAccessControl должен присутствовать параметр REG_DWORD с именем учётной записи, в контексте которой работает ферма/служба поиска, и значением «1»;

2) В под-ключе \Diag должен присутствовать под-ключ с именем VSS модуля для службы поиска SharePoint (в нашем случае должен быть под-ключ с именем «OSearch16 VSS Writer«):

В нашем случае обнаружилось, что под-ключа «OSearch16 VSS Writer» нет.

В такой ситуации некоторые граждане предлагают выдать полные права доступа для учётной записи фермы/службы поиска на под-ключ \Diag. Однако, если присмотреться к действующим разрешениям на этот ключ реестра, то можно заметить, что запись в него разрешена локальной группе безопасности «Backup Operators«.

Включаем учётную запись фермы/службы поиска в эту группу на нашем виртуальном сервере SharePoint со службой поиска и перезагружаем этот сервер.

После перезагрузки удостоверимся в наличии ключа реестра «OSearch16 VSS Writer» и увидим, что владельцем этого ключа является учётная запись, включенная нами ранее в группу «Backup Operators».

После этого снова попробуем создать контрольную точку виртуальной машины в оснастке Hyper-V Manager.

В нашем случае контрольная точка создалась успешно и в гостевой системе виртуального сервера SharePoint ошибка с кодом 8194 больше не появляется.

Теперь можно проверить, как изменилась ситуация в Veeam Backup & Replication. Убеждаемся в том, что в ходе выполнения задания резервного копирования для ВМ успешно создаётся, а затем автоматически удаляется временная контрольная точка, и, как следствие задание VBR отрабатывает без ошибок.

Стоит отметить, что описанная проблема является не проблемой VBR, а проблемой корректной настройки прав доступа для сервисных учётных записей SharePoint. При этом в официальном документе «Plan for administrative and service accounts in SharePoint Server» мне не удалось найти каких-либо явных указаний по включению сервисных учётных записей SharePoint в группу «Backup Operators» или каких-либо схожих по смыслу рекомендаций.

 Using Backup and Restore to back up your system or files for computer protection but receive a Volume Shadow Copy Service error? This post shows you some specific Windows VSS errors and the corresponding solutions, and an easy way to keep PC safe so that you can easily restore the computer to its previous state in case of system accidents.

What Is Volume Shadow Copy Service (VSS)

Shadow Copy is a technology in Microsoft Windows, allowing users to make manual or automatic backups/snapshots of computer volumes or files. It is also known as Volume Snapshot Service, Volume Shadow Copy Service or VSS.

What is VSS? Microsoft defines it as follows:

“The Volume Shadow Copy Service (VSS) is a set of COM interfaces that implements a framework to allow volume backups to be performed while applications on a system continue to write to the volumes.”

This service requires the file system to be NTFS so as to create and store shadow copies. And the copies can be created by any Windows component using this technology on local, external and removable volumes or network locations, such as when creating a scheduled Windows backup or automatic system restore point.

If this service is stopped, all components depending on the service are still not working. And you may encounter some Volume Shadow Copy service errors in Windows 10/8/7 when backing up or restoring OS. Besides, VSS errors may also happen on Windows Server 2008, Server SBS 2011, Server 2012, etc.

In the following paragraphs, we will walk you through some specific errors as well as the solutions in Windows PCs.

«The backup application could not start due to an internal error:
