Things I have learnt this week.

  • Backups are good.
    • If for instance your colo box breaks.
  • Tested backups are better.
    • Best to test them before your box breaks.
  • Automated backups are better still.
    • Humans forget to do things. Machines rarely do. So your backup may not be as recent as yo u think.
  • How to backup svn
    • svnadmin dump $repo | bzip2 > svndump.bz2
  • Checking which disk you are replacing in a degraded mirrored pair is a good thing
    • Your filesystem dieing or going back in time is not fun. See previous points

Having learnt these things I have made my backup regime better and have made sure its croned and does backup the stuff I need. I s hould also start putting more stuff in my svn repo.

This clusterfuck did annoyingly lead to losing about a weeks worth of data on the Randomness Guide to London which was particularly galling since one of the reason for doing it was I trusted myself more with the data. bah
