Do you use CrashPlan to backup your Mac? If so, CrashPlan version 11 was released earlier in March. CrashPlan should be granted a permission known as Full Disk Access so it’ll be able to backup any file. CrashPlan released a 3 minute video containing instructions on how to grant Full Disk Access. The instructions vary slightly if you’re using macOS 12 Monterey or older or macOS 13 Ventura or newer. In the video, the instructions for macOS 12 Monterey and older start at the 40 second mark. The instructions for macOS 13 Ventura and later start at the 2 minute and 10 second mark.
