Editors' Review


Instead of mucking around with removable media, Crashplan offers up a distinct alternative. Banking on ubiquitous high-speed Internet access and more than one computer per household, this service allows you to back up your entire computer to as many discreet locations as you can manage. This includes Crashplan's servers, a second PC of yours, or even your friend's computer.

Designed for PCs and Macs, Crashplan's backups are encrypted before they're sent out. The backup process runs effortlessly in the background over a high-speed network, but we wouldn't recommend it to anyone still on a dial-up modem. The simple and intuitive interface makes preference changes easy, whether you're adding or dropping files from the backup process or choosing a new backup location.

The benefit of off-site safety and security could potentially save you thousands of dollars, as anyone who has had to salvage a fire-damaged hard drive knows. Crashplan charges 10 cents per gigabyte per month to use their servers, but the company discourages this option. Given the ever-dropping cost of memory and storage drives, Crashplan may not be the wave of the future, but it's nice to have a choice for backing up essential files other than shelling out for yet another hard drive.

"Reliable, fast, secure."

March 26, 2011  |  By nothere--2008

 |  Version: CrashPlan 3.0.3


- Simply works (For about 2 yrs, with >400 GB data)
- Stays completely out of your way once configured
- Very efficent incremental backup method
- Support from CrashPlan is very good (for my experience)
- All deleted files are being saved


- The configuration tool is usable, but not very Mac-like
- User interface is a bit quirky (also not very Mac-like :)


Most importantly: CrashPlan is an online backup service - and like all these services it costs money.

There is a free version, which is okay for backing up to an external harddisk. But for online storage, you should choose CrashPlan+ Unlimited (unless your data is < 10GB). The last time I compared (1 yr ago), the prices were better than the competition.

About the software:

The software itself is a Java-based tool, which works, but that the user interface has some quirks: Some options are difficult to find, others not very comprehensible. Here's room for improvement. But since you usually configure your backup plan only once, that's no major drawback.

Really great is CrashPlan when it comes to performance and security:

- All your data is encrypted locally (with your own key if desired) before being transmitted to the online storage. The encryption methods are more than sufficient.
- The incremental backup mechanism is very intelligent. If files are modified, only the modified parts of the file are being transmitted. So if you create a copy of a big video file, the data is only being uploaded once (not like Time machine which in this cases makes two copies). Especially for an online service this is a great benefit, but also for backups to an external HD, CrashPlan often is much faster than Time Machine.
(But for local backups I'd prefer time machine, which allows you to access the files directly, instead of having an archive file, like CrashPlan does)
- Deleted files (deleted after backing them up of course) can be kept an unlimited amount of time, which is also a good feature. (Only useful if you purchase Crashplan+)

Data security:

- Since I can't restore and compare some hundred GB, I check the data consistency from time to time with some files, which are easy to recover and compare. Until now I had no problems.
(But of course you somehow have to trust the vendor in this case).


At two occasions I contacted support and recieved a fast and competent answer.


I gave 5 points, because the only drawback is the quirky UI. And since the tool works cross-platform, that's understandable here.
Otherwise a very much recommended service, with frequent updates, good support and a good pricing scheme.

"Dumps your backup without warning"

March 24, 2011  |  By mortenz06

 |  Version: CrashPlan 3.0.3


Good for backing up very small files


Slow upload speed, dumps you backup,


It is way cheaper, faster, more secure buying an external hard disk and storing it at a friends house.
