    Hello, good article, but if you mentioned for each cloud storage how many GB are per free account, that would be great.

    • Ravi Saive says:


      Thanks for finding this article useful, yes we do agree that we would’ve mentioned about storage per account, but their storage changes regularly, so its difficult for us to check every-time and update the article, you can get the details about storage on their official page..

      your point is noted, but they keep change their storage very ofenly, so

    Numbers 10 (Yandex Disk) and 11 (Bitcasa) aren’t open source. It’s the same as saying Amazon S3 is free.

    You missed one: http://barebonescms.com/documentation/cloud_storage_server/

    Replace 10 or 11 with the above software?

    • Gunjit Khera says:

      Accept your point.
      Thanks for updating about cloud storage server
      Would try to replace above 10 and 11 with this

  8. Yannis says:
