Big businesses use cloud services. You and I use cloud storage services like DropBox, Google Drive, and Amazon Cloud Drive every day. But, with each you have to trust your data on other people’s systems. With ownCloud, an open source file sync and share project, which began as a KDE project, you can keep your data on your servers and decide what other public cloud services you want to integrate into your personal cloud.
OwnCloud is primarily as an Infrastructure as a Service (IaaS) cloud service. With it you can store your files, folders, contacts, photo galleries, calendars and more on a server of your choosing. You can then access that storage from your mobile device, your desktop, or a Web browser. You can also sync your date with local devices and share your data either with the world at large or specific approved users.
With the new, just released version, you also now get file versioning, which allows you to “rollback” to previous versions; file-level encryption, Web-based drag and drop file management, and a built-in Open Document Format (ODF) preview.
