      .SYNOPSIS

      .EXAMPLE
      Get-RubrikVM 'Server1' | New-RubrikSnapshot -Forever
      This will trigger an on-demand backup for any virtual machine named "Server1" that will be retained indefinitely and available under Unmanaged Objects.

      .EXAMPLE
      Get-RubrikFileset 'C_Drive' | New-RubrikSnapshot -SLA 'Gold'
      This will trigger an on-demand backup for any fileset named "C_Drive" using the "Gold" SLA Domain.

      .EXAMPLE
      Get-RubrikDatabase 'DB1' | New-RubrikSnapshot -ForceFull -SLA 'Silver'
      This will trigger an on-demand backup for any database named "DB1" and force the backup to be a full rather than an incremental.
