Files are written individually to each disk so if any disk(s) fail only the data on the failed disk(s) is lost. New disks can be added without rebuilding the array.
It is available in most Linux distros' repositories.
Introductory article about mhddfs:
Interesting. What advantages does this provide over JBOD? What about ZFS?

Carbonite and Backblaze still have reasonably priced cloud backups that cost only around $60/year or less. One doesn't even need to use a cloud backup service to have an offsite backup. A simple external drive is all that's needed for an offsite backup. It can be kept in a locked drawer or locker at work or school, a the home of a trusted friend, relative, or neighbor, or in a safe deposit box at a financial institution.
Of course, an external drive is still the best, inexpensive solution for onsite backups.
The cost for extra drives needed for backups are a bargain compared to the price of data recovery that comes with no guarantee of success.
Correct me if I am wrong here, but when I looked into those five dollar a month "unlimited backup" plans, they were always "unlimited backup" with an asteriks. One plan I was looking at actually capped you at about 1TB of storage. I don't think I can back up tens of terabytes of data to a service like that without paying for a business class service.
Carbonite.com has a Basic plan that is $59.99/year (you have to pay for the full year upfront but that amounts to only the equivalent of $5/month). There is no limit on how much you can backup altogether. See Carbonite's FAQs
. Your ISP may put a limit on how much you can upload in a month.
Also, you have to manually tell Carbonite to backup files over 4GB. Just right click on the filename, click on Carbonite, then click on Back This Up. If you have a lot of 4GB+ files in a folder, the quick and dirty way to tell Carbonite to back them all up is to right click on the folder, then Carbonite, then Back This Up.
Certain file extensions, such as .exe and .dll are not automatically backed up by Carbonite so you have to tell Carbonite to back them up, same as 4GB+ files. However, when you download them back from Carbonite, the file extension will have changed. All one has to do is replace the file extension with the correct one. However, I can't always remember which file got which extension. I've found that it's easier to just "sandbox" the files for installing a program in a zip file. I save all the installation files of programs I download in folders. I zip the all the files in each download. Carbonite will then automatically backup the .zip file.
The asterisk you referred to merely states you need to use a Business Plan to back up Windows Home Server. All other current Windows OSs are supported by the Personal plans.
Backblaze is pretty much the same as Carbonite.
Crashplan's Small Business Plan is more expensive than Carbonite's and Backblaze's personal plans but have the advantage that all deleted files are versioned forever, unlike Carbonite and Backblaze, which retain deleted files for only 30 days. Also, Crashplan has a version for Linux, unlike Carbonite and Backblaze which are limited to Windows and Mac.
