Returns all databases on the given instances without a full backup in the last three days.
Note that the property LastFullBackup is a custom object, with the subproperty Date of type datetime and therefore suitable for comparison with dates.

Filters for the databases that had a copy_only full backup done as the last backup.

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

Specifies one or more database(s) to process. If unspecified, all databases will be processed.

-ExcludeDatabase

Specifies one or more database(s) to exclude from processing.

-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.
