DESCRIPTION

This is only an implementation of the script created by Paul S. Randal to find what percentage of a database has

changed since the last full backup.



https://www.sqlskills.com/blogs/paul/ne ... ll-backup/





PARAMETERS

-Database [<System.Object[]>]

The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will

be processed.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

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.
