I've had a good experience with Kopia [0] for over a year. Linux and Windows boxes all writing to the same repository, which is synchronized to both B2 and a portable drive every night. The one thing it lacks that I'd like is error correction, so I store it on a RAID1 btrfs system. ECC is apparently being developed [1], but is currently experimental and I believe requires a new repository.

I too used to use Crashplan! It steadily went downhill over the years though, so I was looking for an alternative.

I ultimately ended up evaluating various options and deciding on Kopia: https://github.com/kopia/kopia -- been using it for the better part of a year and loving it!

It's basically everything I wanted out of the box: content-addressed storage with built-in deduplication, built-in encryption, compression, many supported backends (filesystem, Backblaze B2, other cloud providers, etc...).

I currently take snapshots on a cron every 30 minutes to a triple-replicated GlusterFS cluster, as well as off-site syncs once daily (B2 currently). Because all of the data is encrypted at rest, I don't mind it sitting in a cloud bucket.
