After seeing Carbonite mentioned on a newsgroup, I thought I would try it. They offer a 15 day free trial. And then US$55 per year to store unlimited backup files on their servers.

I selected a few folders and let it rip. Took about 4 hours to upload my selected folders.

Then it was SUPPOSED to upload any altered files “soon” after they were altered. I had several files that were not uploaded again more that 24 hours later. This is not what they said in their spiel. It says the files will be uploaded whenever the running service detects in-activity on the PC. Well, I left it in-active for a couple of hours and still no upload.

Actually, here is what they say on their site:

When your computer is idle, Carbonite automatically backs up new and changed files. You don’t have to do anything! When you’re using your computer, Carbonite goes to sleep so it will never slow down your computer or internet connection.

I would be loathe to try it again. It is just not for me. But it may well suit someone whose files are not altered too often. If you think you may like it, go ahead. But check that your files are actually being uploaded once changed. The initial upload went very well, but not the uploads about a week into the trial.
I give it a rating of 2 out of five

UPDATE: 20091005

Chasing down the problem where a changed file is not backed up automatically as advertised by Carbonite, I have found this in their FAQ area…

When Carbonite detects that a file has been modified, it checks to make sure that the file has remained unchanged for 10 minutes before the file is made eligible for backup. (By default, a modified file is backed up only once every 24 hours so that you’ll have the opportunity to restore the previous version if necessary.)

That would be why then! Carbonite goes on to say that i can manually right-click the file and select to force it to “Backup as soon as possible”. That sure conflicts with their sales pitch shown above, where they say:-

When your computer is idle, Carbonite automatically backs up new and changed files. You don’t have to do anything!

So it is not very suitable for situations where an important file (or group of files) are NOT automatically backed up!
