Start-WBFileRecovery

Start-WBFileRecovery

Starts a file recovery operation.

Syntax

Parameter Set: Default
Start-WBFileRecovery [-BackupSet] <WBBackupSet> [-SourcePath] <String> [[-TargetPath] <String> ] [[-Option] <WBFileRecoveryOptions> ] [[-Async]] [[-NoRestoreAcl]] [[-Recursive]] [[-Force]] [ <CommonParameters>]

Detailed Description

The Start-WBFileRecovery cmdlet starts a file recovery operation. For file recovery, you must specify the backup set from which to recover the file, along with the file that you want to recover.

To browse the volumes in backup, use the Get-WBBackupVolumeBrowsePath cmdlet.

Parameters

-Async

Indicates that Windows PowerShell® returns immediately after it starts the backup and does not display status messages.

-BackupSet<WBBackupSet>

Specifies a backup set object that contains the backup set from which you recover files.

-Force

Indicates that the cmdlet starts the recovery operation without prompting you for confirmation. By default, the cmdlet prompts you for confirmation before it proceeds.

-NoRestoreAcl

If specified, then security attributes for the files are not restored after recovery.

-Option<WBFileRecoveryOptions>

Specifies an object that contains file recovery options. The options specify the action to take when a file that you recover already exists in the same location. The acceptable values for this parameter are:

-- SkipIfExists: Causes Windows Server Backup to skip the existing file and continue with recovery of the next file.

-- CreateCopyIfExists: Causes Windows Server Backup to create a copy of the existing file and not overwrite it.

-- OverwriteIfExists: Causes Windows Server Backup to overwrite the existing file with the file from the backup.

If you do not specify this parameter, the cmdlet uses the CreateCopyIfExists option by default.

-Recursive

Indicates that Windows Server Backup recovers the files from the folders that you specify along with files in folders that are subordinate to those folders. By default, the backup operation recovers only files that reside directly under the specified folders.

-SourcePath<String>

Specifies the file path that you recover from the backup. You can prefix the file path with a volume browse path that you get from the Get-WBBackupVolumeBrowsePath cmdlet.

-TargetPath<String>

Specifies the location where recovered files reside after the recovery. If you do not specify this parameter, the backup operation recovers files to their original locations.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• WBBackupSet, WBFileRecoveryOptions

  The file recovery process specifies a backup set object that contains the backup set from which you recover files. The recovery process uses file recovery options when you recover files to their original locations and the file that you recover is already present in the original location.

Outputs

The output type is the type of the objects that the cmdlet emits.

• System.String

  If you do not specify the Async parameter, the recovery operation displays status messages at periodic intervals until the recovery is complete. While the recovery operation runs you can use the Get-WBJob cmdlet to get the status of the operation. After the operation is complete, you can use the Get-WBJob -Previous 1 command to get the completed recovery status.

Examples

Example 1 :Recover files to their original location

This command recovers the file at the path "C:\Dir1" from the backup set named $Backup and restores it to its original location. Because the command includes the Force parameter, the backup proceeds without confirmation prompts.

PS C:\> Start-WBFileRecovery -BackupSet $Backup -FilePathToRecover C:\Dir1 -Recursive -FileRecoveryOption CreateCopyIfExists -Force

Recovering files from C:\Dir1 :
Completed.

Example 2: Recover files to a new location

This example recovers the file named C:\Dir1\File1.txt to the alternate location F:\Dir1.

The first command uses the Get-WBBackupVolumeBrowsePath cmdlet to get the volume browse path for the file that you recover. The first element of the Volume array within the backup set stored in the variable named $Backup specifies the volume from which to obtain the backup files.

The second command checks the path that you obtained from the first command for a file named "File1.txt".

The third command restores the file named "File1.txt" to the path "F:\Dir1".

PS C:\> Get-WBBackupVolumeBrowsePath -BackupSet $Backup -VolumeInBackup $Backup.Volume[0]
