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

Re. the Java error - I too still get that, but it so far does not appear to be affecting CrashPlan functionality. iNotify relates to realtime scanning of the filesystem so unless you plan to backup your NAS to another unit running CrashPlan, I think you can safely ignore it.

libcups2 is a bit of a pain. Netgear appears to have a custom version of the library in their firmware and so you have to force that to be overwritten when installing OpenJDK. Given the v2 devices don't support networked printing anyway I doubt this will cause any real issue.

If the suggested command "apt-get -f install" doesn't work try this:

dpkg -i --force-overwrite /var/cache/apt/archives/libcups2_1.4.4-7+squeeze1_armel.deb

Then try the install again.

Note: I take no responsibility if this change does break things. Plus there's a strong possibility a firmware update will restore the Netgear version of libcups2 which may then break CrashPlan, requiring libcups2 to be updated again. Philippe's java suggestion may be a better option in this case. The perils of being an early adopter...
