The database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed.

The database(s) to exclude. Options for this list are auto-populated from the server.

-Type

By default, this command measures the speed of Full backups. Valid options are "Full", "Log" and "Differential".

Alias
Required False
Pipeline false
Default Value Full
Accepted Values Full,Log,Differential,File,Differential File,Partial Full,Partial Differential
-DeviceType

Specifies one or more DeviceTypes to use in filtering backup sets. Valid values are "Disk", "Permanent Disk Device", "Tape", "Permanent Tape Device", "Pipe", "Permanent Pipe Device" and "Virtual Device", as well as custom integers for your own DeviceTypes.

Alias
Required False

Default Value
-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.

Alias
Required False
Pipeline false
Default Value False
