Storing Redo Log files under /tmp location might cause the production Server run out of free space, which can lead to the Oracle Server to go down if no actions have been performed in advance.
This article explains how to change the Oracle Redo log file location during Application-Aware Backup.
Linux-based Oracle Server:
Place VeeamOracleAgent.xml to the Veeam agent starting location (it is /tmp by default)
Make sure that the /location path has appropriate permissions for write/read.
Windows-based Oracle Server:
Create the following registry key and value on the Oracle VM:
Key: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\
String value (REG_SZ): OracleTempLogPath
