Would a storage block level incremental like zfs work?

PG's incremental backup is essentially WAL logs applied to a point in time. I am talking about true incremental backup where the db backs up only the changed blocks after the last full backup. In a DW system where most of the time it is append only, it makes a huge difference in backup time.
I believe there is one tool which looks at mtime/atime of each of the data file and takes the decision to back it up or lot. Not sure how robust it is.
