I wanted to update CrashPlan to the latest version. So I download the latest Linux install and what I found after attempting to install was that I needed to uninstall the existing version before installing the new one.

The following steps

Stop the CrashPlan process from running

/etc/init.d/crashplan stop

Manually delete the following directories

/usr/local/crashplan

/var/lib/crashplan

/usr/local/var/crashplan

Manually delete the following file

/etc/rc2.d/S*crashplan

Once completed I followed the steps from my previous how to install post
