NFS 共有がディスクへのバックアップストレージデバイスとして使用できることを確認する方法

Article: 100058727
Last Published: 2023-07-24

Product(s): Backup Exec

問題

Backup Exec は、UNC パス形式 (\\サーバー名\フォルダ名 など) を使用して、NFS 共有をディスクへのバックアップストレージデバイス (B2D) として使用することをサポートしています。

このドキュメントでは、NFS 共有が B2D として使用できることを確認する方法について説明します。

 

エラーメッセージ

N/A

 

原因

現時点では、検証済みで認定された NFS デバイスはありません。お客様は、NFS デバイスまたは NFS 共有を B2D として使用できることを確認できます。

 

解決策

1. Backup Exec サービスアカウント (BESA) を使用して Backup Exec サーバーにログオンします。

2. コマンドプロンプトを開きます。

3. Backup Exec がインストールされているフォルダに移動します。

C:\...> cd C:\Program Files\Veritas\Backup Exec (デフォルトの場合)

4. 次のコマンドを実行します。

C:\...> b2dtest -d -w \\server-name\folder-name

-d: (デフォルト指定) NFS デバイスまたは NFS 共有についてコメントの入力を抑制します。

-w:(作業フォルダ) 検査対象の NFS 共有を UNC パス形式で指定します。

 

制限事項:

  • 簡易災害復旧 (SDR: Simplified Disaster Recovery) では、Backup Exec サーバーの復旧時に NFS 共有を使用することができません。リモートサーバーは、稼働中の Backup Exec サーバーと NFS 共有を使用して復旧できます。

  • NFS 共有からのバックアップはサポートされていません。

 

b2dtest コマンドの出力例:

C:\Program Files\Veritas\Backup Exec>b2dtest -d -w \\storage1\nfs\export1

06/27/23 16:22:41 Backup Exec (TM) B2D Compatibility Test 
06/27/23 16:22:41 Build 22.0.1193 
06/27/23 16:22:41 
06/27/23 16:22:41 This tool can take up to several hours to complete.  The 
06/27/23 16:22:41 amount of time it takes is dependent on the host computer as 
06/27/23 16:22:41 well as the underlying appliance technology.  It is 
06/27/23 16:22:41 recommended that this tool be run at a time when there will be 
06/27/23 16:22:41 minimal impact on business operations. 
06/27/23 16:22:41 
06/27/23 16:22:41 For the tool to run successfully, the target location of the 
06/27/23 16:22:41 test must contain at least 4,339,073,024 bytes of available 
06/27/23 16:22:41 space.  Furthermore, any credentials supplied must have 
06/27/23 16:22:41 sufficient privileges to create, read, write, and delete 
06/27/23 16:22:41 directories and files on the appliance.

06/27/23 16:35:38       The storage path does not support persistent ACLs. 
06/27/23 16:35:38       It is recommended that you review the security applied 
06/27/23 16:35:38       to the storage to ensure that it is properly protected.

06/27/23 16:35:38 Reparse Points - WARNING - Reparse points not supported on appliance: (0x32) The request is not supported. 
06/27/23 16:35:38       The appliance does not support reparse points.  Some 
06/27/23 16:35:38       of the advanced B2D technologies such as GRT may not 
06/27/23 16:35:38       function. 
06/27/23 16:35:38 
06/27/23 16:35:38       For GRT to function correctly, either the B2D path 
06/27/23 16:35:38       or the temporary path for GRT operations must be an 
06/27/23 16:35:38       NTFS partition that supports reparse points.  If this 
06/27/23 16:35:38       is not the case, GRT operations will fail.
