I like to use sudo instead of becoming root. One of the many benefits to this approach is logging. Everything is logged to /var/log/auth.log for later review. However, by the time I went to look, /var/log/auth.log

My first big Tarsnap backup
NOTE: I wrote this post nearly two years ago, in May 2015. It has been sitting ignored and unloved in my Drafts. I’ve just published it today. I’m big on backups and I use Bacula. I have about 18 TB on about 350 tapes and about 10 TB of backups on disk. I want more. I last used Tarsnap back in July 2010 (I know that because I found the old Tarsnap registration

Moving from shelves to racks
The time has come for me to move from shelving to racks. My first thought was to list the various racks over the years. Look below for old photos and links to the posts I lifted them from. Why a rack? In the past, I have always built my own servers, computers, from parts. I always chose tower cases for space and quiet. A large fan and heatsink can be easily mounted in
