[Discuss] CrashPlan Home is discontinued - what's next?

[Rich Braun]

As of next summer, there won't be any more low-cost CrashPlan backup service
for us Linux users. I liked the fact that its backup engine supports both the
CrashPlan cloud service and private backups between servers.

There are some others, like the ones reviewed here, but nothing ideal:

I always use two separate services (at the moment, CrashPlan plus a homebrew
set of scripts based on rsnapshot) because one's bound to fail.  What's your
strategy? And what will fill the CrashPlan void?
