Jared,
Managed to get those 2 remaining zenpacks installed. Not sure what I was doing wrong initially, but I tried it again after lunch and they installed successfully. Not sure what's going on with the backups. I looked for the test one I ran yesterday and it's in /opt/zenoss/backups. I don't know if that's the right location for backups. Didn't see any errors when restarting services for Daemons.
