Aside from some minor glitchy interface behavior, CrashPlan is a fairly simple backup utility. I successfully created a backup from 2 Macs and 1 PC to an external drive on a third Mac. My biggest complaint with this software, is it's speed. This thing is slow as molasses on an internal Gigabit network. I'm seeing consistent speeds of about 30Mb/sec (that's Megabits, not MegaBytes). Backing up 140GB from one drive to another, on the same machine, will take approximately 10 hours. Backing up 145GB from one machine to a second machine will take a "supposed" 56 days at a whopping 270Kb/sec.

I'm not sure how it's doing it's backup, but it certainly is NOT taking advantage of my Gigabit backbone network.

I know someone who signed up for the Crashplan monthly service, they have a Verizon DSL connection, which is inherently slow anyway. They successfully backed up approximately 75Gigs of information, but it took well over a month to complete.

I would like to see this feature added:

Be able to see list of files waiting to be backed up. Maybe with option to remove from backup set from list.

To the MacUpdate staff: it's a little confusing that this application is listed as both free, and $7.49.

Simply awesome value!

The initial backup takes a while, but once done, this is sublimely useful!

I'm looking for a good offsite backup, and I thought I'd found it in CrashPlan. I signed up for the 30 day trial, selected what I needed backed up and let 'er rip. Twenty-nine days later, as it was just about to finish uploading my data (yes, 29 days later) there was a glitch in the process and it started over from scratch. Ouch.

I shelved it for a couple of weeks and decided to do a back up to a local external drive. That works like a champ. The program also gives you the option to keep a backup on a friend's machine (or vice versa, a friend can put an encrypted back up on your machine). Great feature.

Cloud storage for huge amounts of data (say, an iPhoto library) just take way too long to get started. However, the features mentioned above are definitely worth looking into.
