Online Backup Comparison

Posted February 17th, 2009 by kyle

I haven’t gotten very far yet reviewing online backup services. I continue to use MozyHome personal files and JungleDisk for business data, which work reasonably well. One nice thing about both of these products is that they run as a Windows service, and their system tray monitor apps don’t need to be running for backups to be performed, which reduces memory and CPU usage.

I have put together a comparison chart for online backup services I have either used or would like to review in more detail at some point. It only includes services that have responded to my email inquiries.

    Nice list, thanks!

    I wonder how reliable is Mozy’s storage? JD uses Amazon S3 which appears to be reliable since it is used by many other startups as well and Amazon’s reputation depends on its stability. Do you know how is Mozy storage is backed up? Is it distributed or my files will be stored in one datacenter?

    I am currently using JD myself (and pay mere cents since I did not upload much of the data yet).

    The most useful JD’s feature to me is that it appears as a Windows drive. I can keep portable programs and scripts directly on it and run them directly. Same with documents – I can edit them directly without worrying about backups. This also helps to work with these files from several computers. And I think JD also can keep old versions of the files although I never really tried restoring them this way.

    Does Mozy simulate a drive as well? Could you please comment if it can be used in the similar way?

    I believe Mozy uses multiple data centers, but I don’t know exactly how it compares to S3 in that regard.

    Mozy provides a virtual drive (shell namespace extension) in Explorer, but not a true drive letter (native file system support) like JungleDisk. It does also add overlay icons in Explorer to indicate which files are backed up, which JungleDisk doesn’t offer.
