-ExcludeDatabase

The database(s) to exclude - this list is auto-populated from the server

-Snapshot

Restores databases from snapshots with this names only. You can pass either Databases or Snapshots

-InputObject

Allows piping from other Snapshot commands

-Force

If restoring from a snapshot involves dropping any other snapshot, you need to explicitly use -Force to let this command delete the ones not involved in the restore process. Also, -Force will forcibly kill all running queries that prevent the restore process.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

-WhatIf

Shows what would happen if the command were to run

-Confirm

Prompts for confirmation of every step.
