说明

此 cmdlet 会将搜索索引备份到指定的备份位置。 cmdlet 必须分两个阶段运行。第一阶段将在运行备份 cmdlet 时备份索引中存在的内容。第二阶段将在开始第一阶段索引备份后，对添加到索引的内容进行差异备份。

示例

------------------示例 1------------------

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 1 -SearchApplication $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

此示例启动默认搜索应用程序的搜索索引的 Phase 1 备份，并将备份存储在位置 \\backuphost\backupfolder。该 cmdlet 存储第二阶段 cmdlet 所使用的句柄文件 backuphandle.txt。

------------------示例 2------------------

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 1 $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

此示例通过重新运行阶段 1 的 cmdlet 来检查备份状态和进度。

------------------示例 3------------------

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 2 -SearchApplication $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

此示例通过使用相同的备份位置和用于阶段 1 的备份句柄文件开始搜索索引备份的阶段 2。 Search Service 应用程序先暂停，然后才能开始第二阶段。

参数

-Abort

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	SharePoint Server 2013, SharePoint Server 2016, SharePoint Server 2019

-AssignmentCollection

管理对象以便正确进行处理。使用 SPWeb 或 SPSite 等对象可能会耗用大量内存，而且在 Windows PowerShell 脚本中使用这些对象需要正确管理内存。通过使用 SPAssignment 对象，可以将对象分配给变量，然后在不需要这些对象时对它们进行处理，以释放内存。在使用 SPWeb、SPSite 或 SPSiteAdministration 对象时，如果不使用分配集合或 Global 参数，则会自动处理这些对象。

在使用 Global 参数时，所有对象均包含在全局存储中。如果未立即使用对象，或未通过使用 Stop-SPAssignment 命令来处理对象，则可能会发生内存不足的情况。
