Update CrashPlan on QNAP

It’s happened to me twice now: CrashPlan stops backing up my files apparently due to a failed software update. I usually don’t know CrashPlan has stopped backing up until I get the weekly email status update. Fortunately, the files that I back up to CrashPlan are not changed often at all, and missing a backup for a couple days isn’t the end of the world.

I have CrashPlan installed on my QNAP (see my previous post about that), and CrashPlan smartly autoupdates their software every now and then. Unfortunately this autoupdate doesn’t seem to work when installed on QNAP. The following instructions should help get CrashPlan updated and running again smoothly.

Connect to the CrashPlan server running on QNAP by first creating an SSH tunnel to QNAP and then open the GUI client locally (connecting to the CrashPlan server through the ssh tunnel). The GUI reports that “CrashPlan Upgrade Failed. CrashPlan failed to apply an upgrade and will try again automatically in one hour…” crashplanupgradefailed

How to upgrade (I had version 3.2.1 installed, version 3.4.1 was available):

Happy CrashPlanning!
