I personally would recommend btrfs specially if you have a ssd hard
disk. Although it supposes some performance lost you will get a more
reliable data consistency and you can check all your data just doing
"btrfs scrub start /" (or "btrfs scrub start / -c Idle" if you don't
want it lags too much your system while working).

I was using also btrfs-send/receieve but ultimately it seems that there
is some problem that causes a CPU bottleneck with my big non-ssd hard
disk. The main ssd disk stills working fine but I am thinking on another
way for incremental backups.

I would like to experiment with borg so I could do backups at file level
adding some cool features like ignore some paths (e.g. '~/.cache') or
restore a single file without uncompressing/unencrypting the whole image
and also have deduplication.
