Backup Solutions for Linux

While there are many options(cp, tar, simplelinuxbackup, fwbackups, rsync, unison, bacula, keep, karchive ... etc) for backing up Linux systems, there does not seem to be a consensus number one option. So, I went through the frustrating process of trying out a lot of options and found my number one. While the particular needs and intentions of specific systems ultimately determines the best backup tool, I went for the simplest solution for my simple problem.

  • First, I don't need data compression since I have plenty of space on my HD. Plus, date compression consumes a lot of CPU which becomes a huge hustle when I am trying to do real work while performing my backups.
  • Second, automatic/periodic/scheduled backups are not needed in my case because I will invoke the backup process whenever I plug in my external HD and am in the mood to perform backups.
  • Third, I don't feel the need for file encryption.
  • Fourth, I don't need incremental backups -- I simply want the latest copy backed up and don't want to worry about earlier versions.

On the basis of what I need (or don't need), I concluded that rdiff-backup was the simplest and best tool for my backups. It is quick, does no compression or encryption by default and works very reliably. Plus, it does not require me to do any conflict resolution (unlike unison) and it builds the latest backup using previous backups and the newest source very efficiently (unlike rsync).

Addendum 06/30/08::
rdiff-backup & keep were all good until I started switching distros like my freaking socks. So, I am adding another requirement to my simple backup tool - portablity and platform-independence. I need something that should work with any distro without my intervention. That final requirement has led me to switch to rsync.

KDE has built a program called keep which basically provides a GUI for doing backups using rdiff-backup. The set up is very simple, and backups could be automated or performed manually. So, it's the solution I have upgraded to.

Slow Acroread Startup in OpenSuSe 11.0

It takes more than 30 seconds for acroread to load on my Opensuse machine the first time and the startup time gets shorter in subsequent attempts. Why? This is not the first time I have come across this problem of slow application startups in OpenSuse. Apparently a lot of people had encountered this problem and they found a simple solution - uninstalling the version of acroread that comes with OpenSuse and installing one from Adobe site yourself. Fortunately, that prescription seems to have solved the problem. My acroread startup time is a few seconds now. Why does a very good Linux distribution like OpenSuse with its wide support and following make so many of these mistakes?!?! Over the years, I have seen Suse/OpenSuse sending buggy distributions that make you wonder if they do much testing before releasing their distro. Here are a few bugs I have come across: The extremely slow startup of Openoffice in OpenSuse 10.0 was one of the reasons I switched to Fedora Core for a while...

The Pervasive Mac vs. Windows vs. Linux Analogy

I'm sure everyone has seen the Mac vs. PC ads on TV where the Mac appears to be confident while th PC is in denial about its deficiencies. Missing from that picture is Linux which is robust, but seeks no attention because it has no commercial ambitions. This Mac vs. PC vs. Linux model can serve as a analogy for many things/phenomena. I would like to make a list of those analogies here. For example, The New York Times recently characterized Hillary as a PC and Obama as a mac on the basis of the design of their websites. The analogy would also work if you think of Hillary as the status quo much like Windows, and Obama as the new thing with great promise, cachet and appeal like the newly reborn mac. It is not obvious who would play the role of Linux, but my choice would be Ron Paul. He has some bold and independent ideas along with a very loyal following even though he has no chance of winning. PC Mac Linux Candidate Hillary Clinton Barack Obama Ron Paul States Northeast West Co...
