It is not easy to sync the own files/mails/contacts/calendars/etc. in order to keep them private (not via a public cloud) and to create regular backups. Furthermore, every solution must be easy to use (at least for my wife ;)) and reliable.
Following is my approach for keeping my files in sync and private. What are yours?
I initially stored my ownCloud data on an external NTFS hard disk. (Yes, this was not a good idea at all.) After some time now I wanted to move the files to a bigger ext4 drive on the same machine. Unluckily there are many posts and articles that are really irritating on the Internet, such as: 1, 2, 3, 4. At least I found some promising hints at the official GitHub forums (this and that) and gave it a try:
If you want to use you own ownCloud installation, you can find several documentation on the Internet on how to set up this server, e.g. the official ownCloud documentation, or installation guides such as this or that or here. But none of these page alone provided enough information for installing a secure server completely from the beginning.
So here comes my step-by-step guide which surely won’t be complete, too. ;) However, hopefully it will help other people while searching for their way to install ownCloud. Additionally I am showing how to upgrade an ownCloud server.
