Backups
Remember it is in your best interest to take a backup of your site:
  • Before running an Update for any release of Joomla
  • Before updating any existing Extensions
  • Before installing any new Extensions.
  • Before deleting any Extension (particular core Extensions)
  • Before moving from subfolder/ to root/
  • Before moving from localhost/ to remote host
  • Before making changes to Access Control Levels.
  • Before editing the core files of Joomla for any reason
    • NOTE:this is not recommended anyway! Except on the rare occasion when an official, approved patch is released prior to a full update being available by the Joomla developers.
  • On a regular basis for your site to protect new content that is added:
    • Frequency for the regular backups varies depending on your site, it's traffic, and changes to the content:
    • it may be every hour
    • it may be 2/3 times a day or more
    • it may be once a day
    • it may be once a week
    • it may be once a month
  • Essentially, any time where if there is a chance for things to go wrong, you always have a backup to fall back to!
Joomla 2.5.x Update Settings
  1. On Joomla 2.5.x make sure that Components ⇒ Joomla Update ⇒ Options is set to the default Long Term Support (Recommended) setting.
  2. If you incorrectly/accidentally set this to Short Term Support you will get advised of Joomla 3.x Updates.
  3. You should only update to Joomla 3.x if you are an experienced user / developer / advanced early adopter.
  4. There is no automatic rewind option from Joomla 3.0.x to Joomla 2.5.x. and no easy manual way of doing this without a backup of the site and database.
