If you create a non-incremental stream of a snapshot, doesn't it
contain all the information necessary to recreate the file system up
to the point the snapshot was created? Now take that stream and drop
it onto a tape (real or VTL) and you would potentially have a back up
(a la ufsdump).
Who uses only one snapshot? Not many people.
At the risk of repeating the Best Practices Guide (again):
The zfs send and receive commands do not provide an enterprise-level
backup solution.
Yes, in its current state; hopefully that will change some point in
the future (which is what we're talking about with GSoC--the potential
to change the status quo).
I suppose, but considering that enterprise backup solutions exist,
and some are open source, why reinvent the wheel?
