Remote backups with rdiff-backup

I set this up a while back, but I needed to make some notes on my setup of rdiff-backup that backs up my colo'd PC to my home fileserver. I've been using it for more than 3 months and it has done a great job - space efficient, time efficient and bandwidth light. I followed the recommended unattended HOWTO and it was easy to setup - even with different OSes (Solaris x86 vs. CentOS), versions of ssh and versions of rdiff-backup itself. Only modifications were:

• In the authorized_keys2 on the source system, I didn't include the from="kitty" bit as the destination PC that I'm pulling from has a dynamic IP
  
• I included --print-statistics in the cron job's command line, redirected the output to a logfile
  
• I setup the three config files/scripts setup to have LogWatch tell me the daily summary of the rdiff-backup results. i.e.:
  • /etc/log.d/conf/logfiles/nyc-backup.conf
    
  • /etc/log.d/conf/services/nyc-backup.conf
    
  • /etc/log.d/scripts/services/nyc-backup

My next step is to get rdiff-backup setup to backup by local fileserver. Right now I have a simple rsync from one drive to the other. The reason I haven't done it yet is that the filesystems were setup without LVM (what was I thinking!). So, I need to clean up, reformat with LVM and then get rdiff-backup setup - maybe even with the snapshot recommendations on the unattended HOWTO page.
