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?
You need to install the Lchown module which provides a perl interface to the lchown UNIX system call, on systems that support lchown. The lchown() call is used to change the ownership and group of symbolic links. To install the same, enter:
sudo apt-get update
sudo apt-get install liblchown-perl

For other UNIX like operating systems
Use your package manager or download it from cpan.org or install it using the cpan command / shell:
cpan -A Lchown
cpan -i Lchown

For rpm based distros, you may wish to also include a reference to the perl-Lchown packages appropriate to their distro / architecture; trying to run cpan builds / installs on rpm systems can be problematic.
Try this:
sudo apt-get install make
sudo apt-get install g++
sudo perl -MCPAN -e ‘install qw(Lchown)’
Thanks very much for the tip: as always there’s more to learn with open source! I’ve had debian and Ubuntu servers for years but just finding out the merits of rsnapshot and etckeeper!
