Rsync: Preserve / Copy Hard Links ( Backup Rsnapshot Directory Tree )

Posted on in Categories , , , , , , , last updated September 8, 2015

I‘m using rsnapshot filesystem snapshot utility to make incremental snapshots of local and remote filesystems for 10 production servers running on RHEL 5.x system. The rsnapshot commands makes extensive use of hard links, so if the file doesn’t change, the next snapshot is simply a hard link to the exact same file. How do I use the rsync command to copy my the entire snapshot directory /raid6/rsnapshot/ (around 4TB) to a remote server for mirroring purpose?

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?
