Thanks. Yes I do keep a full system image backup, and it gets updated either bi-weekly or monthly (all of my data is stored on a secondary drive anyway, so even if it's been a week or two since the last full system image, all I have to do is restore some Internet bookmarks mainly, and probably update a few applications, which is nothing. Then once the OS is back up and going again, I'll attach my second HDD with my data and do AV scans on it, so I do have a disaster plan, and obviously know about clicking malicious email links, visiting web pages that are in question, etc (I'm an IT person anyway, but just haven't ever used REadyShare on a router, and have always been skeptical of the security of NAS devices to this day.. I always just felt that having your data stored on an actual computer that is actively scanning for viruses was better than letting one of the clients know that the NAS device contains a virus. But I guess in the end, if someone really wants to get my data, they'll find some why to get it.
I do keep two backups: one on-site (for if I accidentally delete something) and one off-site (in case of fire, theft, etc). So I've got that covered.
I'll probably just play with it and see how it goes. Again, I don't plan on storing any programs on the drive that will be attached, but again, technology has gotten so advanced that even pictures and plain text files can have code embedded in them that could lead to an infection. I'll just set one of my PCs to scan the drive periodically at night.
