For every Oracle VM whose transaction logs you want to back up, Veeam Backup & Replication defines how to ship logs to the backup repository. Transaction logs can be transported in the following ways:
- Directly from the VM guest OS to the backup repository. This method is recommended — it does not involve additional resources and puts less load on the VM guest OS.
- Via log shipping servers. If it is not possible to establish a direct connection between the VM guest OS and backup repository, you can configure Veeam Backup & Replication to use a log shipping server.
A log shipping server is a Microsoft Windows or Linux server added to the backup infrastructure. You can explicitly define what servers you want to use for log shipping or instruct Veeam Backup & Replication to automatically choose an optimal log shipping server. Veeam Backup & Replication chooses the log shipping server based on the location of the Oracle VMs and log shipping server.
Location of Log Shipping Server and VMs
When choosing a log shipping server for the job, Veeam Backup & Replication considers the location of the Oracle VM and log shipping server. Veeam Backup & Replication uses the following priority rules to select the log shipping server:
- Log shipping server is located on the source Microsoft Hyper-V host performing the role of the on-host backup proxy.
- Log shipping server and Oracle VM are located in the same network.
- Log shipping server and Oracle VM are located in different networks (the production infrastructure is isolated from the backup infrastructure).
That is, when choosing a log shipping server, Veeam Backup & Replication will give the top priority to a VM that is located on the source Microsoft Hyper-V host.
Log shipping servers are assigned per job session. When a new job session starts, Veeam Backup & Replication detects log shipping servers anew. Veeam Backup & Replication can also re-detect available servers during the job session. If a log shipping server becomes unavailable for some reason, Veeam Backup & Replication will fail over to another log shipping server.

If you do not want to use some servers for transaction logs transport, you can manually define what server Veeam Backup & Replication must use as a log shipping server in the job settings. It is recommended that you assign the log shipping server role to a number of servers for availability purposes. |
