Regading these, i had tried, and tested, quite a few nline stirage solutions (e.g Carbonite, Dropbox) mostly......and all have ther own "quirky" limitatons to the pont i'd be better off going back to a NAS (since i would have more control). For example, i have a pc and Mac on my network, running these online solutions on both, (not at the same time, of course). Carbonite, i see, favours Windws more, than Mac's since it has a backup drive (mapped drive in explorer). I would love this on Mac, as this was my primamy goal. Point my wallpapaers folder to the online storage drive. but its not possible Then i tried DropBox, which does have ths. This also, turned out to be good, but very limited stirage for my needs Only up to 500 Gig on a paid account. My goal is really Unlimited storage, combine with a backup drive that works on Mac too. Things which lack on Carbonite are, File version not available on Mac, over 200Gig they also start throttling your connection to 100k upload speed (that sux). But im sure thy have their reasons. The thing i can't get is when your uploading your using *Your* own bandwidth, not theirs. You are using theirs to download, but the limitation only applies to uploads only. I don't think its possible though to have a backup drive on Mac with Carbonite, so i'm searching round to see if there is anywhere else i can turn to. All this, and more.....makes me wannna go back to using a NAS..... I don't mind the price ether, its more the lack of features available to which OS"s.
