This doesn't buy you anything. ZFS isn't like traditional backups.
If you never send another full, then eventually the delta from the original
to the present will become large. Not a problem, you're correct, as long as
your destination media is sufficiently large.
Unless I am mistaken, I believe, the following is not possible:
On the source, create snapshot "1"
Send snapshot "1" to destination
On the source, create snapshot "2"
Send incremental, from "1" to "2" to the destination.
On the source, destroy snapshot "1"
On the destination, destroy snapshot "1"
I think, since snapshot "2" was derived from "1" you can't destroy "1"
unless you've already destroyed "2"
Am I wrong?
Yes - what you describe is how I maintain my remote backups!
