Btrfs offline dedupe [3.12]
+
+ -
+ Btrfs generally does COW rather than updating in-place, allowing
+ snapshots and file copies to defer the actual copying and save
+ space
+
+ -
+ Filesystems may still end up with multiple copies of the same
+ file content
+
+ -
+ Btrfs doesn't actively merge these duplicates, but userland can
+ tell it to do so
+
+ -
+ Many file dedupe tools are packaged for Debian, but not one that
+ works with this Btrfs feature, e.g. bedup
+
