2.10 Creating a Snapshot-Based Backup of Oracle Linux Database Server

A backup should be made before and after every significant change to the software on the database server. For example, a backup should be made before and after the following procedures:

• Application of operating system patches
• Application of Oracle patches
• Reconfiguration of significant operating parameters
• Installation or reconfiguration of significant non Oracle software

Starting with Oracle Exadata System Software release 19.1.0, the SSHD ClientAliveInterval defaults to 600 seconds. If the time needed for completing backups exceeds 10 minutes, then you can specify a larger value for ClientAliveInterval in the /etc/ssh/sshd_config file. You must restart the SSH service for changes to take effect. After the long running operation completes, remove the modification to the ClientAliveInterval parameter and restart the SSH service.
