Known Issue: Legacy FileVault Prevents Carbonite from Backing up Files

Summary:

Apple's original disk encryption software, now known as Legacy FileVault, prevents Carbonite from backing up files.

Cause:

Due to Legacy FileVault's encryption method, Carbonite cannot recognize files that were previously backed up. As a result, Carbonite re-backs up existing files because they appear as new files whenever you log off, restart, or shut down your Mac.

This article applies to:

Carbonite Plans	Products	Platform	Version
Basic, Plus, Prime, Core, Power, and Ultimate (Not sure?)	Safe and Safe Pro (Not sure?)	Mac	2.x and 1.x (Not sure?)

Environment:

macOS 10.12.x and older

Note: macOS 10.13 High Sierra and newer only support FileVault 2 which was initially released in 10.7.4 Lion. If you are on 10.13 or newer and have FileVault active, it is actually FileVault 2 and this article does not apply to you.

Solution:

You cannot use both Legacy FileVault and Carbonite on the same computer. If you wish to use Carbonite instead of Legacy FileVault, follow the instructions below to disable Legacy FileVault.

1. Click on the Apple icon at the top-left corner of the screen and select System Preferences.
   
2. Within the System Preferences window, click on Security & Privacy.
   
   If you don’t see this option, click to get back to the main System Preferences screen.
3. Click the FileVault tab.
4. Click Turn Off Legacy FileVault.
   
   Note:
   If you only see the Turn Off FileVault button as pictured below, then you have already moved to FileVault 2 and disabling should not be necessary.
