With the death of CrashPlan, we had to move our backups elsewhere. Ended up using restic, rclone, Google Cloud Storage, and others to get it done, and it's working great so far.
Wrote up the process as a (work-in-progress) blog post here, if there's any interest:
Fun fact, Google has a 12 month, $300 credit for their cloud services, so depending on your storage needs, you can get free backups for a year.
