Mozy home, i have had so many issues trying to recover files for people that have it setup and it is really a joke. I even had a client that has the pro and it took 2 weeks to resolve an issue with restoring a quickbooks database.

In my opinion have a local backup. I currently have 9tb in my antec 9 hundred case and looking for a really good way to compress everything down into a few tb drives.

Simple, lots of features, unlimited space for $19 /yr.
There is no third party software that runs, but if you can configure rsync, you can encrypt your data just like mozy and all the others do.

I have contacted actual devs there, at times over the years. It is always the same sort of thing – like this article says. They sprikle some wording that sounds about right – but they do not want you to actually be able to do store 10 computers of data via 1 for 4.95 a month. For a while they were talking about a WHS specific version, but essentially they could not get their client to work well. That was about 1.5 years ago. My understanding is it would have to be a fresh code write.

Finally – the reason you cannot install is because Mozy sees it as Windows Server and they have the app disabled to install. Technically it will work with it, just just block it. There are ways around it, but it is not worth it.

I’m now a happy CrashPlan customer, it’s not WHS specific, but it runs on any Window’s OS and is actually cheaper than Mozy, either way it’s better than Mozy Home!
