- Always monitor your backups.
- Always backup your monitoring.
- Always investigate failures; work out how to monitor it to catch it quicker next time (hopefully before it fails).
Backups without monitoring is no backup at all; if your backups fail, you won’t know until you try to use them.
A note about RAID
Unmonitored RAID 1/5/6/10 is no better than a single disk; as each disk pops, you’ll never notice until the last one goes.
A note about UPS’s
UPS’s fail, OK.

I think the main point is nicely summed up – when “the community” gets inside this device there will be a possibility of realising the potential of an intelligent picture frame — the kind of self-populating, automatically updating, no-user-input required device that you would give to your parents and siblings to keep in touch. They shouldn’t have to navigate through my Snapfish albums manually – it should just happen!
