Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance.

-Database

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

-ExcludeDatabase

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

-Since

All backups taken on or after the point in time represented by this datetime object will be processed.

-Last

If this switch is enabled, only the last backup will be measured.

-Type

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

-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.
