I've decided to invest in Online backups (and I probably should have done that a LONG time ago.)

Anyhow, I checked out a few services.  I was extremely tempted by Mozy and Carbonite.  $5 a month for unlimited backup seems pretty cool.  (Oh, Backblaze does this too.)

I had to rule out Carbonite. It doesn't backup external drives, and my Mac has a bunch of my media stored on an external drive because it's internal drive is only 160 gb.  So, I need the ability to back up attached drives.

That leaves Mozy and Backblaze.  Both seem pretty much the same, as far as I can tell . They'll both backup any mounted drive (which means that even though they will not backup NAS, they would probably backup a usb attached Drobo.  wow.)  $5 a month, unlimited automatic backups. 

Is anybody using these services and if so, how has your experience been?
