If there are some files that you would like to delete from our serves that have already been uploaded, you can go to the Backblaze Control Panel (PC) or Backblaze Preferences (Mac) and click 'settings', then go to 'exclusions' and add these directories or file types to the exclusions list.
Once this is done, the files will be removed from our servers in 30 days.
The only way to delete these files immediately would be to delete your entire backup, to do so:
1. Visit https://secure.backblaze.com/user_signin.htm and sign in to your Backblaze account with your email address and password.
2. Click on the "Account" link in the upper left hand corner
3. Select your unwanted computer from the drop down list of computers.
4. Click the "Delete Computer" link next to it
*IMPORTANT! Doing this will delete all of the backed up data from this computer!
