[CentOS] amanda and selinux

Anyone familiar with the selinux policy for the amanda backup software package? I'm getting lots of data not being backed up. For example, under /home there are 2 directory trees owned by root. Those get backed up, user home dirs do not.

No AVC denials nor messages in /var/log/messages or journalctl log. But if I turn off selinux enforcing, or set amanda_t type to permissive, complete backups are made.

I expected the selinux policy would have allowed amanda to be able to read all files. Else, how does one make backups?

I'm seeing this on CentOS 7.2, Fedora 24 & 25. Amanda packages from the respective distro repos. As far as I can tell, the selinux policies are the same in all three. But then, I know little selinux speak.
