Backup

Posted in Computers by Armchair Guy on December 13, 2007

I used to use Dar/KDar for backup purposes back when I was using SuSE 10.2. I’ve switched to Ubuntu, and it seems KDar is no longer packaged for Ubuntu. It got me thinking: what are the features that I want in a simple desktop backup application? Here are some in no particular order:

  1. Network awareness. This is something I missed in Dar, which could only write to a directory on the system, which meant I had to ssh-mount a remote filesystem before I could back up to it.
  2. Incremental and Full Backups.
  3. A good scheduler. That is, it should be possible to specify the frequency and type of incremental and full backups, and a purge schedule for old backups.
  4. Software independence. Dar used its own proprietary format, which forces me to use Dar to look at any of my backups. With KDar no longer available, it is quite painful to try to look at the contents of any of the older backup files. I have to get Dar to extract them somewhere, browse them and then delete them later. Something uses simple tar or tar.gz is much better; I can use Konqueror etc. to browse inside them directly.
  5. Encryption is good if I’ll be using NAS, otherwise it’s not as important to me.

Maybe I’ll add more requirements later.
