I'm looking for suggestions on software I can use to back up the Pi5 to
the NAS. I've seen conflicting suggestions on various sites, so thought I
would come to the fount of all knowledge that is Usenet.

I think this depends on what is the meaning of "NAS".
In many (most?) cases, NAS means a VFAT file system projected through
CIFS/Samba to the LAN. The unit does not have a user-accessible
operating system. In some cases there is Linux under the hood, but no
way to install applications on it.

In such an environment, /rsync/ is not an option.

Things are quite different if we are talking about a full-fledged *nix
system performing the NAS function. In such a case, I would recommend
formatting the NAS drives with ext4 and exporting them both with Samba
and NFS and then either running rsync through NFS or over ssh.

So ... if this is really about one of those "hardswired CIFS"type of
NAS, what is the best method?
