XFS and Ext4 have metadata checksumming. But only BTRFS has data checksumming.
A XFS developer from Oracle currently implements back references,
deduplication and even more checksumming, but I think its still only metadata
checksumming, Heise Open Thorsten Lemhuis wrote about data checksumming
instead. I don´t know where this is heading, but at a point in time maybe XFS
even gains snapshots. That said there where patches for snapshotting Ext3/4 as
well.
Of course any of this is off topic here.
