Using a non-root user as a host user
If the host user that you want to use is a non-root user or does not have root permissions for the MongoDB server, then you must complete the following steps:
Ensure that the host user credentials that are configured using the tpconfig command are of the host user account that is used to configure the MongoDB cluster (MongoDB daemon's host user account).
Give that host user the ownership rights to all the directories that you have mentioned in the
mongodb.conffile. This step ensures that the backup host can access the directories to copy the required files for backup operations. For example, the user needs rights tomdbserver_location,logdir,oplog_location.Ensure that the host user has ownership of the MongoDB database path and its contents. This ownership is required for the backup as well as restore operations.
On the server where MongoDB is installed, add the host user in the
sudoersfile.
