John Oliver addresses the need for encryption in an hilarious way. The clip is ~18 minutes, but well worth it.
If you still think that encryption is only used for evil (terrorism, child pornography, etc.), and that governments / security agencies should need (backdoor) access to your data..... Well, I'm not gonna end that sentence.
My 'little' off-site Raspberry Pi backup/remote storage project will probably use a combination of Bittorrent Sync and rsync. The latter will be used to backup personal information, but I want that data to be absolutely secure. So I want to use encryption. Preferably by using container that I can mount (e.g. Truecrypt or the Apple OSX encrypted disk images).
The problem with containers is that many backup solutions tend to backup / transfer the entire container when a change occurred. Thankfully, rsync only copies the changes.
