If your phone is rooted, you can use e.g. Linux Deploy to install a full Linux distribution. Then, you can set up regular ol' OpenSSH, mount /sys and /data under the Linux chroot, and rsync as usual.

I use this method to rsync to btrfs snapshots (+ raw copies of non-filesystem partitions) to make daily incremental backups of the entire phone. (Restoring said backups is a bit more involved, but I verified it's doable.)

I'd backup to a more reliable filesystem than btrfs. In my experience you will eventually randomly lose data with btrfs. I have lost all trust in it.

"raid" 1/0 and 10 are stable, others are not. Theoretically btrfs can protect against bit-rot where other fs's typically don't.

Theoretically that might be the goal. In my experience data melts away like butter on btrfs.

Backups are by definition redundant, however, btrfs is still the only Linux filesystem with its featureset. Let me know when ZFS on Linux supports shrinking or cloning file ranges.
