Planning Area BAck up cube to save more than 1 request

Hi All,

We presently back up our planning areas every day in late evenings and delete the previous requests. Now since we had couple of issues where data is lost and wanted 2 days old data back but could not. So we want a process where we can have 5-6 days requests and after say 5 days the requests older than 5 days wil get deleted automatically.

Can any one advice how this can be done.
