Cause

Resolution
- 確認 SharePoint VSS Writer 服務設定為「登入身分」 SharePoint Farm 系統管理員帳戶 （<網域>\<使用者>）
- 身為 SharePoint 系統管理員，在 SharePoint PowerShell 中執行下列命令：
stsadm -o unregisterwsswriter stsadm -o registerwsswriter
SharePoint 2022 推出了新的 PowerShell Cmdlet：
Register-SPVssWriter Registers the SharePoint VSS Writer service on the local server. Unregister-SPVssWriter Unregisters the SharePoint VSS Writer service on the local server.
- 確認 SharePoint VSS 撰寫器服務啟動類型設定為「自動」
- 將伺服器場管理員帳戶添加到 SharePoint 前端伺服器上的本地管理員組。
- 重新啟動 SharePoint VSS Writer 服務。
- 確認已列出 SharePoint VSS 寫入器 （在命令提示字元中使用「vssadmin list writers」檢查）
