Network Appliance-like snapshots?

[Ken Ambrose]

I seem to recall that someone was working on NetApp-like snapshot
functionality for the 2.4(.5?) kernel series.  These aren't LVM-like; this
is an actual heirarchy of logical files that are actually the original
file, with subsequent deltas (thus preserving disk space quite nicely).  I
would *LOVE* to have this as part of my dream RAID system for my job.  
Searches, alas, seem to turn up either LVM or NetApp/NFS hits, and nothing
pertinent.  Perhaps I'm just going senile in my old age?

Thanks,

-Ken

No - you're not getting senile (yet). I think you are thinking of the
Veritas File System (also Tru64's AdvFS). But good luck getting a port
to Linux!
