Since Dropbox seems to get hacked every 15 minutes I decided it was time to leave them. (Dont forget to permanently delete your files as they as stored on the server if you might want to restore them!)
I haven’t yet found a alternative. I want to store the files on my own server in ENCRYPTED form.
There’s 2 Dropbox alternatives that’s currently being developed that I find interesting that both encrypts and can use FTP for storing the files.
Here they are:
