Pogoplug is a network drive adapter coupled with a web service that allows you to access a personal drive from anywhere on the Internet without having to worry about firewalls and other security issues. You plug a drive into the Pogoplug, connect the unit to power, and you can securely access that data no matter where you are, from your laptop, another computer, or from an iPhone.
Today, Pogoplug has announced support for journaled HFS+ formatted drives. You can now plug in almost any drive formatted for use on the Mac and it'll work with Pogoplug.That's great, because the last few times I dredged up Disk Utility (from /Applications/Utilities), it was to re-format drives to use with the Pogoplug system. (You can also turn off journaling from the Terminal, if you're so inclined, via the 'diskutil' command.)
What's particularly cool is that Pogoplug is currently working on developing remote backup assistance. They don't support Time Capsule yet, but the Pogoplug developers say they're working on having "the Pogoplug play nice with [Time Capsule and other remote storage devices] and allow our users to back up to their home drives automatically and regularly."
Being able to set up off-site backup drives with just a simple plug-and-go sounds like an awesome business opportunity for anyone with a central router and a whole bunch of USB hubs. But even if you're setting up your off-site backup at your sister-in-law's ("Sure, go ahead and plug in that...um...thing. Can I take it out if I need to vacuum?"), that's a fine way to keep your backups physically remote from your primary computing space. At just $99 plus the cost of a hard drive (the lifetime service is included free), a bargain.
