Rsnapshot WARNING: Could not lchown() symlink "/path/to/file" Error and Solution

Posted on in Categories , , , , , , , , , , last updated November 3, 2009

I got rsnapshot based backup server up and running for my network under Debian Linux 5.x. But, whenever I run a backup job using the following command:

rsnapshot -v -c /root/rsnapshot.server1.conf hourly
I get the following messages on screen:

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?

CentOS / RHEL Configure Yum Automatic Update Retrieval and Installation

The yum command line tool is used to install and update software packages under RHEL / CentOS Linux server. I know how to apply updates using yum update command line, but I’d like to use cron to manually update packages where appropriate. How do I configure yum to install software patches / updates automatically with cron?
