New-WBFileSpec

  • Reference
Module:
WindowsServerBackup

Creates a backup file specification.

Syntax

New-WBFileSpec
   [-FileSpec] <String[]>
   [-NonRecursive]
   [-Exclude]
   [<CommonParameters>]

Description

The New-WBFileSpec cmdlet creates a WBFileSpec object that contains a backup file specification. A WBFileSpec object defines the items that a backup includes or excludes. You can add a backup file specification to a WBPolicy object as a source for backup.

You can use this cmdlet to include multiple files, folders, or volumes. Specify volume paths by using volume drive letters, volume mount points, or GUID-based volume names. If you use a GUID-based volume name, ensure that it ends with a backslash (\). You can use wildcard characters (*) in file names to specify a path to a file or to specify a file type to include or exclude.

If you specify a path to exclude from the backup, that path must be part of an inclusion file specification in the policy. Otherwise, the backup ignores the exclusion path.

Examples

Example 1: Add a file to a backup file specification

PS C:\> $Filespec = New-WBFileSpec -FileSpec "C:\Sample\1.jpg"

This command creates a file specification and adds the file named C:\Sample\1.jpg to it.

Example 2: Add a folder recursively to a backup file specification

PS C:\> $Filespec = New-WBFileSpec -FileSpec "C:\Sample"

This command creates a file specification and adds the contents of the C:\Sample folder to it. Because the cmdlet does not include the NonRecursive parameter, the backup includes the contents of this folder and its subfolders.

Example 3: Add a folder nonrecursively to a backup file specification

PS C:\> $Filespec = New-WBFileSpec -FileSpec "C:\Sample" -NonRecursive

This command creates a file specification and adds the contents of the C:\Sample folder to it. Because the cmdlet includes the NonRecursive parameter, the backup includes the contents of this folder but not the contents of its subfolders.

Example 4: Exclude files from a backup file specification

PS C:\> $Filespec = New-WBFileSpec -FileSpec "C:\Sample\*.mp3" -Exclude

This command creates an exclusion file specification for MP3 files in the C:\Sample folder. The backup excludes MP3 files in C:\Sample and its subfolders and stores it in the variable named $Filespec.
