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?

We establish connections to remote systems without supplying a password, however I do not want to store my password less keys ( passphrase-free keys) on my servers. ssh-agent, takes care of keys with passphase, which allowing me to easily have ssh-agent process per system per login session. How do I dramatically reduces the number of times I’ve to punch my passphrase from once per new login session to once every time my local server is rebooted? How do I use keychain utility for all my backup scripts for secure passwordless login?
