BCV vs Clone vs Snapshot vs SRDF, and deleting asssociation between source and target, to delete the target?

Hi,

I think i know basics of these replciation technologies -

BCV - local mirror - its full copy of the source device (can be detached and used as back up) - dependent (can be used only after split/detach)

Snapshot - local - point in time - to restore (cannot be detached as these are just pointers - delta replicas - virtual replicas) (point-in-time??? - what does it mean?)

CLone - looks like it can be used as both BCV and Snapshot and superior technique (independent - can be used as seperate storage any time) - ((point in time - what does it mean?)

SRDF - clone, but on remote array

In all the cases there will be a source and target. and i am guessing inoder to delete the target device, first the relationship needs to be broken.

And also documentation says snapshots and clones are point in time whereas bcv is synchrnoized copy ( i know what a sync copy is), but i didnt get what a point in time means?

Once the relationship is broken, deleting target devices is same as deleing normal devices.

And there are probably different ways to delete replication relationship (probably same??).

If any one get add details, that will be helpful especially regarding the basic differences and removing the relationship

Btw, my main focus is on BCV, but looks like all these replication techiniques somehwhat similar (at least the basics like having source, target, association etc...)

----

Looks like this one is very good source for BCV vs Clone.

But it doesnt focus on snaps, srdf and deleting the relationships between source and target...
