WARNING: Could not lchown() symlink “/nas/.rsnapshot/hourly.1/server1.example.com/etc/alternatives/locate”
WARNING: Could not lchown() symlink “/nas/.rsnapshot/hourly.1/server1.example.com/etc/alternatives/nc.1.gz”
WARNING: Could not lchown() symlink “/nas/.rsnapshot/hourly.1/server1.example.com/etc/alternatives/jexec-binfmt”
WARNING: Could not lchown() symlink “/nas/.rsnapshot/hourly.1/server1.example.com/etc/alternatives/servertool”

How do I fix this problem?
