VMWare Snapshots

Okay, I want to make sure that I do this correctly.  I have a VM and about 3 days ago created a snapshot for testing purposes.  We were having a problem with Veeam backups and they were indicating it might be a problem with creating the snapshot.  Veeam was able to discover the problem with a VSS provider and now the backup is working.

So what to do with the snapshot.  My thought is that I just delete it, but very early on I tried this and deleted the snapshot and the server died.  It happened to be the exchange server and we had to completely rebuild.  So I am a little nervous.

So have I got this right or backwards.

If I create a snapshot that is in place for a week and i want to make it go away (update worked fine, testing was fine, etc.  ) I click the button that says "Delete".  Server is fine and we go our happy way with any changes that have been made in the last several days still intact.

If I create a snapshot and the server isn't fine, I click the button that says "Go To" and I am right back to where I started and I lose any changes that were made in the last several days.
