        Article Summary

        Backblaze Computer Backup is designed to back up your entire computer. By default, you cannot select specific folders to back up. Instead, you can back up only certain folders by setting the client to exclude all of the folders that you do not want to back up.

        After you add files to the exclusions list, they are deleted from Backblaze servers in 30 days.

        Directory (folder) exclusions prevent all files and sub folders of the directory from being indexed or included in a Backblaze backup. The default directory exclusions cannot be removed, but you can specify additional exclusions.

        Configure Exclusions

        1. Open the Backblaze Client Control Panel.
        2. Click Settings, and select the Exclusions tab.
        3. Add a folder exclusion.
          1. Click Add Folder to open the folder selection window.
          2. Select the folders that you do not want in your backup, and click Choose Folder.
            Exclusions apply across all drives. Excluding a folder excludes any folder with that name regardless of location.
          3. After you select all of the folders that you want to exclude, click OK.
            The exclusions that you select are applied the next time the Backblaze software backs up your data.
        4. Add a file type exclusion.
          1. In the text field, enter the file extensions, separated by commas, that you want to exclude.
          2. Click Apply.
        5. Limit the maximum file size.
          1. Select a value in the Do not backup files larger than: field.
          2. Click Apply.
        6. Click OK to accept the new exclusion settings.
