Many of our clients swap backup destinations so they always have a safe copy offsite. (Although we now have automated cloud destinations that replace this manual process!) Simply ejecting a disk can be a problem because CrashPlan keeps "ties" with the disk and doesn't want to see it go. The solution is this...
- From your server (use Screen Sharing if it's "headless") launch the FC CrashPlan Controller from the dock.
- Select "Stop CrashPlan PRO" (see above) and enter your server's local admin username and password.
- Once "The CrashPlan PRO engine has been stopped" (see below) click OK and eject/swap the drives. To properly eject a drive, drag the disk icon to the Trash. Do NOT simply unplug or power off the drive.
- IMPORTANT: Once the drives are swapped (and the new drive powered on), launch the FC CrashPlan Controller again to "Start CrashPlan PRO".
