My current backup is with Back In Time on multiple external HDDs. This is nice as it has snapshots and encryption (with LUKS). It protects against hardware failures, user errors and malware attacks. The only downside is that I have to manually start it, and this means that I won't do it every day.
For a while I used a non-public directory on my webspace and did a backup via SSH. This was automatic, though not encrypted on the server side and space was limited. If could be encrypted with EncFS, though that is not as secure as LUKS.
I would like to have an online backup that would be encrypted and with snapshots. The amount of data is around 250 GB. The one service that I know of is SpiderOak. It has a Linux desktop client that encrypts the file on my computer. The only caveat with it is that is hosted in the USA, though I would prefer one in Germany.
The alternative would be buying a small computer as a NAS running Linux with LUKS. But that does not really help me if I am not at home.
Are there more services that offer the following?
- Linux support
In the meantime I found these articles:

It seems that the following services are worth looking into:
