Recently I got this error below during the Oracle redo log backup:

My backup job configuration is about a Veeam Linux Agent in an Oracle Linux and the application aware was configured to backup logs with 15 minutes interval and delete logs older than 24 hours:

This kind of configuration is very common on critical databases and I have this same configuration in various environments.
So, the first thing I assumed is that the cause of the problem was not on the Veeam side.
Looking on Linux side I discovered that the user used on Guest Processing configuration needs to be part of the oinstall group on OS.
So, the only thing I did was put this user on this group:
usermod -aG oinstall <my_user>

 After that, all Oracle redo logs started to being process successfully:
