Deduplication is where the file system replaces repeated data with a pointer to the earlier occurrence.
It is used heavily in things like zipping where speed of execution is traded with file size.
I would imagine that where a file system needs/tries to be fault tolerant then deduplication would not be a good thing.
BTRFS is a lot newer design and has better fault tolerance built into the base design, however I suspect deduplication only occurs across files and not so heavily within files. _________________ "Just think of it as leaving early to avoid the rush" - T Pratchett
