Actually, I re-ran this scenario and this is what I observed:
ROOT-1.vmdk
^
|
ROOT-1-000001.vmdk (Snapshot 1)
I take another snapshot of the VM:
ROOT-1.vmdk
^
|
ROOT-1-000001.vmdk (Snapshot 1)
^
|
ROOT-1-000002.vmdk (Snapshot 2)
Let's say I revert to Snapshot 1.
I see the following behavior:
ROOT-1.vmdk
^
|
ROOT-2-000001.vmdk ROOT-2-000003.vmdk
(ROOT-2-000001.vmdk and ROOT-2-000003.vmdk are children of ROOT-1.vmdk.)
This brings up a couple questions:
1) If those two snapshots are siblings, then why in the GUI do I see that
one is listed as the parent of the other?
2) What happened to the data that was stored in ROOT-1-000002.vmdk? What
happens if I try to revert to Snapshot 2? That snapshot no longer appears
to be backed by a file on the datastore.
Thanks!
