What is sqlwriter.exe?
The genuine file is a software component of Microsoft SQL Server by Microsoft Corporation .
The Microsoft SQL Writer Service («sqlwriter.exe») installs automatically when SQL Server is installed. Although a computer can have multiple instances of SQL Server, of different versions, SQL Writer is a shared service and only present once. Windows Installer always installs the latest binary in «C:\Program Files\Microsoft SQL Server\90\Shared\sqlwriter.exe». This service must be running and should not be removed if the Volume Shadow Copy (or VSS) backup service is in use. (If not using VSS for backup and restore, «sqlwriter.exe» is not needed.) It resolves the conflict that would otherwise occur because of the SQL Database Engine having database files locked with exclusive access when the Windows backup programs want to copy them. It briefly freezes I/O in a given SQL Server Database Engine instance so that data is not backed up or restored while transactions affecting it are incomplete, such as between deleting moved data in one place and writing it in another.
The .exe extension on a filename indicates an exe cutable file. Executable files may, in some cases, harm your computer. Therefore, please read below to decide for yourself whether the sqlwriter.exe on your computer is a Trojan that you should remove, or whether it is a file belonging to the Windows operating system or to a trusted application.

Что такое sqlwriter.exe?
Процесс, известный как SQL Server VSS Writer (версия — 64-битная), принадлежит программному обеспечению Microsoft SQL Server VSS Writer или Microsoft SQL Server (версия 2012 Express LocalDB, 2016 LocalDB 2014, LocalDB RC0 2016) или Microsoft VSS Writer для SQL Server (версия 2016, 2014, 2012) или собственный клиент Microsoft SQL Server или модуль записи VSS SQL Server или собственный сервер Microsoft SQL Server (www.microsoft.com).
Описание: Sqlwriter.exe не является необходимым для ОС Windows и вызывает относительно немного проблем. Sqlwriter.exe находится в подпапках «C: \ Program Files», обычно C: \ Program Files \ Microsoft SQL Server \ 90 \ Shared \ . Известные размеры файлов в Windows 10/8/7 / XP составляют 131 776 байт (8% всех случаев), 15 7 720 байт и еще 21 вариант. Он работает как фоновый сервис SQLWriter. Сервис предоставляет интерфейс для резервного копирования / восстановления сервера Microsoft SQL через инфраструктуру Windows VSS.
Программа не видна. Файл sqlwriter.exe имеет цифровую подпись. Это не файл Windows. Вы можете удалить эту программу в панели управления. Sqlwriter.exe способен мониторить приложения. Поэтому технический рейтинг надежности 17% опасности, но вы также должны учитывать отзывы пользователей.
Важно: некоторые вредоносные программы маскируют себя как sqlwriter.exe, особенно если они находятся в папке C: \ Windows или C: \ Windows \ System32. Таким образом, вы должны проверить файл sqlwriter.exe на вашем ПК, чтобы убедиться, что это угроза. Мы рекомендуем Security Task Manager для проверки безопасности вашего компьютера. Это был один из лучших вариантов загрузки The Washington Post и PC World .
Аккуратный и опрятный компьютер — это главное требование для избежания проблем с sqlwriter. Это означает запуск сканирования на наличие вредоносных программ, очистку жесткого диска с использованием 1 cleanmgr и 2 sfc / scannow, 3 удаления ненужных программ, проверку наличия программ автозапуска (с использованием 4 msconfig) и включение автоматического обновления Windows 5. Всегда не забывайте выполнять периодическое резервное копирование или, по крайней мере, устанавливать точки восстановления.
Если вы столкнулись с реальной проблемой, попробуйте вспомнить последнее, что вы сделали, или последнее, что вы установили до того, как проблема появилась впервые. Используйте команду 6 resmon, чтобы определить процессы, которые вызывают вашу проблему. Даже для серьезных проблем, вместо переустановки Windows, лучше восстановить вашу установку или, для Windows 8 и более поздних версий, выполнить команду 7 DISM.exe / Online / Cleanup-image / Restorehealth. Это позволяет восстанавливать операционную систему без потери данных.
Security Task Manager показывает все запущенные сервисы Windows, включая внедренные скрытые приложения (например, мониторинг клавиатуры или браузера, авто вход). Уникальный рейтинг риска безопасности указывает на вероятность того, что процесс является потенциальным шпионским ПО, вредоносным ПО или трояном. B Malwarebytes Anti-Malware обнаруживает и удаляет спящие шпионские, рекламные программы, трояны, клавиатурные шпионы, вредоносные программы и трекеры с вашего жесткого диска.

Volume Shadow Copy Service (VSS)
The Volume Shadow Copy Service (VSS) captures and copies stable images for backup on running systems, particularly servers, without unduly degrading the performance and stability of the services they provide. VSS has following main merits:
- VSS provides fast volume capture of the state of a disk at one instant in time, i.e a shadow copy of the volume. This volume copy exists side by side with the live volume, and contains copies of all files on disk effectively saved and available as a separate device.
- VSS minimize application downtime. The VSS shadow copy exists in parallel with a live copy of the volume to be backed up, so except for the brief period of the shadow copy’s preparation and creation, an application can continue its work. The time needed to actually create a shadow copy, which occurs between Freeze and Thaw events, typically takes about one minute. While a writer’s preparation for a shadow copy, including flushing I/O and saving state (see Overview of Pre-Backup Tasks), may be nontrivial, it is significantly shorter than the time required to actually back up a volume-which for large volumes may take hours.
Windows in-box VSS Writers (From MSDN):
Windows XP/Server 2003 in-box VSS Writers:
MSDEWriter
The MSDEWriter writer is a VSS Writer for SQL Server. MSDEWriter is included with the VSS framework in Windows XP and Windows Server 2003. MSDEWriter works with SQL Server 7.0, SQL Server 2000, and SQL Server 2005.
SqlServerWriter
The SqlServerWriter writer is a VSS Writer for SQL Server. SqlServerWriter is included with SQL Server 2005. SqlServerWriter only works with instances of SQL Server 2005.
Windows VISTA/Windows 7 in-box VSS Writers
Registry Writer
The registry writer is responsible for the Windows registry. Beginning with Windows Vista and Windows Server 2008, the registry writer now performs in-place backups and restores of the registry. On versions of Windows prior to Windows Vista, the registry writer used an intermediate repository file (sometimes called a "spit file") to store registry data.
In Windows Vista and later, the registry writer does not report user hives.
COM+ REGDB Writer—COM+ Class Registration Database Writer
Beginning with Windows Vista and Windows Server 2008, this writer is responsible for the contents of the %SystemRoot%\Registration directory. The COM+ catalog is a file in %SystemRoot%\Registration with a name that follows the pattern Rxxxxxxxxxxxx.clb, where xxxxxxxxxxxx is a 12-digit hexadecimal number. There can potentially be multiple such files if COM+ applications have been configured on the computer. The file that contains the current COM+ catalog is the file with the largest value of xxxxxxxxxxxx.
The COM+ class registration database depends on a registry key being backed up and hence needs to be backed up and restored together with the registry.
MSSearch Service Writer
Beginning with Windows Server 2008, this writer exists to delete search index files from shadow copies after creation. This is done to minimize the impact of Copy-on-Write I/O during regular I/O on these files on the shadow-copied volume.
To install this writer on the server, you must install the File Services role and enable the Windows Search Service.
WMI Writer
Beginning with Windows Vista and Windows Server 2008, this writer is used for identifying WMI-specific state and data during backup operations. The data includes files from the WBEM repository.
BITS Writer—Background Intelligent Transfer Service (BITS) Writer
Beginning with Windows Vista and Windows Server 2008, the BITS writer uses the FilesNotToBackup registry key to exclude files from the BITS cache folder. The default cache location is %AllUsersProfile%\Microsoft\Network\Downloader\Cache.
In addition, the BITS writer excludes the following files from backup: the BITS state files (qmgr0.dat and qmgr1.dat), the BITS debug log file, and BITS partially downloaded files.
If the BITS download destination file is an SMB file, the client account must have a trust relationship to the server, or else backups may fail.
ASR Writer—Automated System Recovery (ASR) Writer
Beginning with Windows Vista and Windows Server 2008, the ASR writer stores the configuration of disks on the system. This writer reports the Boot Configuration Database (BCD) and is also responsible for dismounting the registry hive that represents the BCD during shadow copy creation. The ASR writer must be included in any backups required for bare-metal recovery. For more information about ASR, see Using VSS Automated System Recovery for Disaster Recovery.
System Writer
- All static files that have been installed. A static file is a file that is listed in the component manifest with the writeableType file attribute set to "static" or "". Static files include all files that are protected by Windows Resource Protection (WRP). However, not all static files are WRP-protected files. For example, game files are static but not WRP-protected so that administrators can change parental control settings.
- The contents of the Windows Side-by-Side (WinSxS) directory, including all manifests, optional components, and third-party Win32 files.
- All PnP files for installed drivers (owned by PnP).
- All user-mode services and non-PnP drivers.
- All catalogs owned by CryptSvc.
Shadow Copy Optimization Writer
Beginning with Windows Vista and Windows Server 2008, this writer deletes certain files from volume shadow copies. This is done to minimize the impact of Copy-on-Write I/O during regular I/O on these files on the shadow-copied volume. The files that are deleted are typically temporary files or files that do not contain user or system state.
Active Directory Lightweight Directory Services (LDS) VSS Writer
Beginning with Windows Server 2003, this writer reports the ADAM database file (adamntds.dit) and the associated log files for each instance in %program files%\Microsoft ADAM\instance N \data, where N is the ADAM instance number. These database log files are required to restore ADAM instances.
Active Directory Domain Services (NTDS) VSS Writer
Beginning with Windows Server 2003, this writer reports the NTDS database file (ntds.dit) and the associated log files. These files are required to restore the Active Directory correctly.
If the computer that contains the NTDS database is a domain controller, the backup application should always perform a system state backup across all volumes containing critical system state information. At restore time, the application should first restart the computer in Directory Services Restore Mode and then perform a system state restore.
Dynamic Host Configuration Protocol (DHCP) Writer
Beginning with Windows Server 2003, this writer is responsible for enumerating files required for the DHCP server role. This writer is an in-box writer for Windows Server operating system versions; it does not ship in Windows Client.
File Server Resource Manager (FSRM) Writer
Beginning with Windows Server 2003 R2, this writer enumerates the FSRM configuration files that are used for system state backup. During restore operations it prevents changes in FSRM configuration and temporarily halts enforcement of quotas and file screens. After the restore is complete, the writer refreshes FSRM with the configuration that was restored. This writer is only present when FSRM (part of File Services role) is both installed and running. This writer is an in-box writer for Windows Server operating system versions; it does not ship in Windows Client.
Windows Internet Name Service (WINS) Writer
Beginning with Windows Server 2003, this writer is responsible for enumerating files required for WINS.
