Is the system backup unable to start (see screenshot attached) due to expired password of nna which's used to run cron job? If yes, how to change its password and ensure NNA service can be running normally?

Login as root to the NNA serevr and run the following to remove the password and set it to not expire. The next time the cron job runs, it should be able to run what is needed as the nna user.

However, user naa doesn't exist in /etc/passwd. Why there's error when running cron job as this user? As such, how to fix backup error?

The error is for the nna user, not for a user called naa.

If nna's password is removed, will this impact service run as this user not able to run normally?

Yes, removing the password will fix the cron job that is failing and allow it to run.

Where's the system backup stored? Is it possible to change its default path?

The backups are stored in /store/backups/nagiosna by default.

To change the path where the backups are stored, you would have to edit this script. Change the rootdir option to the path you want. The path you use has to be writable by the nna user and the nnacmd group.

You will also have to edit this file and change the path /store/backups/nagiosna to the new location so the Web interface will look there for the backup files and display them in the GUI.

which proceeses and services does nna use for? Will password removal of this user cause service outage or interruption?

Cron jobs, the nfcapd daemon that captures the data use the nna account to run and removing the password will not cause service outage or interruptions.
