The CrashPlan architecture allows versioning, continuous backup on OS X, Windows, and Linux desktop clients, and Code42 offers PROe private cloud servers for each of these platforms as well. I've used CrashPlan PROe (private cloud server with standard CrashPlan client) for three years, in multiple small business settings. It's a five star product, with five star support, but a few small but persistent browser compatibility issues, and one major licensing problem, keep it from earning all five stars from me.

The one time I experienced an error in backing up, we just had our IT person remote in, and fixed it.

Crashplan has been so helpful in helping users understand their clear and concise backup history, as well as help us identify issues before there was a problem. We have had so much minimal data loss in comparison to previous years.

I've been using Crashplan for a very long time. Primarily, for the past five years, I've used it to backup server backups, personal files, and long-term storage from my backup server. I got to the point of needing to restore the files as my local backup server RAID died and was unrecoverable. No problem, I have Crashplan... Or so I thought. It took about a week to restore all of the files. None of them were usable. They did a fantastic job if I wanted to back up the folder structure. If I wanted the data in said folders, tuff! Contacting support is a waste of time. They take, on average, three business days or more to reply, and when they do, it's generally very vague or things you've already told them you tried, didn't work, and you're looking for help. "Oh, did you try..." Yes, yes, I did, and I told you that, and it didn't work.I've tried restoring my files using multiple versions of their software, on multiple operating systems, and with different levels of permissions on the systems where the files were being restored. I get the same results every time: the folder structure and some of the archives downloads, but that's it. All of the archives are corrupt; they will not extract, and those that do are filled with thousands of empty files, no clue why. I paid for five years of service to simply run their applications because that's all it did, as far as I can tell.Simply put, STAY AWAY!

Very Satisfied. Easy to use and maintain.
