[GUIDE] Installing CrashPlan for WD My Cloud - Cloud backup

My Cloud OS 3 Personal & Network Attached Storage My Cloud

I’m trying to install CrashPlan but apt-get seems not to be installed (says: -sh: apt-get: not found) on my EX2 and furthermore any intent on installing it gives me this error:

./jre/bin/java: line 1: ELF4?: not found

./jre/bin/java: line 2: syntax error: unexpected “(”

Am I doing something wrong?
