NetBackup™ Snapshot Manager for Cloud インストールおよびアップグレードガイド

OCI のスナップショットジョブからのバックアップの Iptable ルール

OCI では、Ubuntu ホストに NetBackup Snapshot Manager を配備するときに、いくつかのデフォルトの iptable ルールを再構成する必要があります。デフォルトの iptable 規則がサービス間でのネットワーク接続の問題を引き起こし、スナップショットからのバックアップ、インデックス付け、バックアップからのリストアの各ジョブが失敗する場合があります。iptable ファイルは、次の場所にあります。

etc/iptables/rules.v4

iptable ルールファイルの内容は、デフォルトで存在するルールをコメントアウトした後、次の例のようになります。

# CLOUD_IMG: This file was created/modified by the Cloud Image build process
# iptables configuration for Oracle Cloud Infrastructure

# See the Oracle-Provided Images section in the Oracle Cloud Infrastructure
# documentation for security impact of modifying or removing these rule
