From the above command it is clear that group oinstall has the permissions to access the files and folders.

If you wanted to create a new user who should be member of oinstall, them command would be

adduser username -g groupname -G oinstall

replace the username with the real name of the backup user.

-g groupname - replace the groupname with the primary group of the user.
-G oinstall - This would be the secondary group of the user.

Once you have the user created, it all depends how you wanted to take the backup.

You could use dump command or tar command or ever rsync the data over to other server or tape.
