CrashPlan+ gives you all the protection of free CrashPlan backup software, plus the added benefit of secure cloud backup and online storage.
Ketil Moland Olsen's insight:
Living in a digital age, most of us have experienced data loss at some point. Sometimes, it means that a report has to be rewritten from scratch, which is of course frustrating. But if it's the priceless pictures of your kids' early years that gets lost when your hard drive breaks, it's downright devastating.
Regular backups on external hard drives helps, but it's often a manual process. And what if your house burns down or burglars break in? The threat of data loss is still very real, unless you have a well developed backup cycle with offsite storage (for instance, storing a recent backup on a external hard drive in your parents' house).
Enter online backup (aka cloud backup). It's been a round for quite some years, but it's only recently, with the rise of synchronous broadband (with high upload speed), that it has become really useful. Now offsite backup can be handled automatically, without everybody having to push external drives around all the time.
I've tested a lot of different online backup solutions during the last couple of years, and in my opinion, CrashPlan+ is by far the best one out there today.
Multiple backup destinations (external drives, other computers, friends, or CrashPlan's online storage) lets you keep copies on multiple locations, which is always a good thing. Different backup sets with different priority lets you prioritize the important files before the less important ones. And effective data deduplication that actually works, means that changes to your files will be backed up without backing up the whole file one more time.
The user interface could have been more intuitive and responsive, but since this is a typical example of "set it and forget it" software, it really doesn't matter. Not before you need to recover those files, at least.
I've been using CrashPlan+ for four years now, occasionally trying competitors to confirm that CrashPlan+ is still on the top of my list. And I'm happy to report that it still is!
