Peculiar why you would not use the ssms and sql agent jobs to configure both the backups and the cleanup.

IMHO, using ssms and sql agent to manage the schedule of backup/cleanup  provides for a single location to look.
The compression for saving space is not worth the overhead for the compressing.
You might be able to use 7zip instead of winrar for the compression.

You can use the following command to remove files older than specific date. The parameter -whatif is added for testing. Remove it to make any permanent changes.
GCI "C:\folder\" | where {$_.LastWriteTime -le $(get-date).AddDays(-5)} | Remove-Item -whatif

Open in new window


You can refer the following article for function to zip files..
http://blogs.msdn.com/b/daiken/archive/2007/02/12/compress-files-with-windows-powershell-then-package-a-windows-vista-sidebar-gadget.aspx

usage:
new-zip c:\demo\myzip.zip
dir c:\demo\files\*.* -Recurse | add-Zip c:\demo\myzip.zip

Hi Thanks for the input
@arnold, i am running SQL Express, so cannot setup the standard backup job in Management Studio. So this is why i am using this powershell sctipt which works really well. Just i need to remove old files.
@Subsan, thanks for the code i will give it a go :)
thanks again
