Crashplan on Duo/NV+ v2? [SOLVED + TUTORIAL]

Progress:



Unfortunately, while I can get the Crashplan engine running, I cannot then use the NAS as a backup target - I constantly get the message "backup disabled - not available" as if the backup location is not available (not true)



Only error report is the following related to iNotify:

Exception in thread "W11700608_ScanWrkr" java.lang.NoClassDefFoundError: Could not initialize class com.code42.jna.inotify.InotifyManager

Quite a few reports of this that I've tried various solutions to (eg modify java tmp dir) but with no success.

Have now run out of time on this so if anyone has any thoughts, let me know
