CrashPlan backup data for your machines is viewable in the SCCM console. This is made available via a custom hardware inventory class. To view the data, simply run the query located under Monitoring->Queries->MIT Queries->CrashPlan (x86) or (x64) depending on your computer's architecture.
The data returned should show the date/time of last backup, size of the backup set, the application name, and the version of CrashPlan. If you are not seeing any CrashPlan data for your computer, then it likely that it has the CrashPlan application installed but it is not backed up.
