Are you looking for a Dropbox alternative? Try ownCloud. Dropbox and ownCloud are both free as well as a paid service. The main difference between the two is that you can run ownCloud from your own server. Like Dropbox, you can access ownCloud from your browser, desktop or smartphone. The ownCloud server software runs on any server, mine runs on Ubuntu Linux, and it doesn’t require special permissions.
The latest version is ownCloud version 6. I was still running on version 4.5. So, the following instructions will upgrade your ownCloud to the latest version on the Ubuntu server. If you have large amounts of data, it would be wise to backup your ownCloud directories. If you don’t have many files, you can opt for a clean install.
Go to your ownCloud directory.
Delete everything except for data and config. You will most likely need sudo to delete your files. I opted for a clean install, so I deleted everything.
ls | grep -v 'data\|config' | sudo xargs rm -r
Download ownCloud. Since I did a clean install, I went up one directory level.
cd .. wget http://download.owncloud.org/community/owncloud-latest.tar.bz2
Unpack the tarball. It will create a new directory ‘owncloud.’
sudo tar xfj owncloud-latest.tar.bz2
Give it write permissions. By default, the owncloud files are owned by nobody. So, you might see an error message saying it needs write permissions to ‘owncloud/data.’ I changed the ownership of the files to Apache, which is www-data.
sudo chown www-data:www-data -R owncloud
Access ownCloud by opening up your web browser and going to your ownCloud URL. If you did a clean install, you will be asked to create a new admin username and password. Otherwise, enter your former credentials. Finally, download the desktop clients as well as the mobile apps and install on your devices.
Synch your files and have fun.
