Backup from snapshot job fails due to connectivity issues when Snapshot Manager is deployed on an Ubuntu host
Explanation:
On OCI, when you deploy Snapshot Manager on an Ubuntu host, the default iptable rules may cause issues with network connectivity between the NetBackup services. These connectivity issues may cause the backup from snapshot, indexing, and restore from backup jobs to fail.
Workaround:
Comment out the iptable rules in the iptable file as shown in the example.
Workaround:
If backup from snapshot needs to be run on Ubuntu deployed NBSM (on oracle cloud) then the iptable rules file should look like this after commenting out the rules present by default:
root@nbsm-host:/# cat /etc/iptables/rules.v4
# 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
