Snapshots in a Process Tree
Imagine that you test software. You can take a snapshot before installing different versions of a program to ensure each different installation began from an identical baseline. This is an example of using snapshots in a process tree.
Snapshots as Restore Points in a Process Tree
Relationship Between Snapshots
The relationship between snapshots is like parent to child.
In the linear process, each snapshot has one parent and one child, except for the last snapshot, which has no children.
In the process tree, each snapshot has one parent, but one snapshot may have more than one child. Many snapshots have no children.
Often you will likely revert to a parent snapshot, but with Workstation 5 you can also go to any child.
