Maintenance Cleanup Task
Applies to: 
SQL Server
SSIS Integration Runtime in Azure Data Factory
The Maintenance Cleanup task removes files related to maintenance plans, including database backup files and reports created by maintenance plans. For more information, see Maintenance Plans and Back Up and Restore of SQL Server Databases.
By using the Maintenance Cleanup task, a package can remove the backup files or maintenance plan reports on the specified server. The Maintenance Cleanup task includes an option to remove a specific file or remove a group of files in a folder. Optionally you can specify the extension of the files to delete.
When you configure the Maintenance Cleanup task to remove backup files, the default file name extension is BAK. For report files, the default file name extension is TXT. You can update the extensions to suit your needs; the only limitation is that extensions must be less than 256 characters long.
Typically, you want to remove old files that are no longer needed, and the Maintenance Cleanup task can be configured to delete files that have reached a specified age. For example, the task can be configured to delete files that are older than four weeks. You can specify the age of files to delete by using days, weeks, months, or years. If you do not specify the minimum age of files to delete, all files of the specified type are deleted.
In contrast to earlier versions of the Maintenance Cleanup task, the SQL Server version of the task does not automatically delete files in the subdirectories of the specified directory. This constraint reduces the surface area of any attack that could exploit the functionality of the Maintenance Cleanup task to delete files maliciously. To delete the first-level subfolders, you must explicitly elect to do this by checking the Include first-level subfolders option in the Maintenance Cleanup Task dialog box.
