There's three ways you can update Backblaze to the newest version:
• Periodically, Backblaze will automatically update all users to the newest version of Backblaze. No action is required from the user.
• You can manually check for updates by pulling down the Backblaze menu bar icon or clicking on the Backblaze notification area / system tray icon and choosing "Check for Updates." If an update is available, you can download and install it. Do not uninstall first.
• You can visit https://secure.backblaze.com/update.htm and manually download the Backblaze installer for Mac or Windows. Do not uninstall, just install over the top of the existing version.
Note, for Network Administrators, https://secure.backblaze.com/update.htm will always point to the newest version of Backblaze.
