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.
