I have seen cases where a software bug in the application gradually
caused data in the database to be changed. It took a while to notice that.
In such a case you want to have a backup from a month ago or more so that
you can extract the data as they were back then and try to repair as much
as possible.

Also, what if a problem was introduced right before the weekend and noticed
immediately afterwards? That might be more than 48 hours ago.

There are other scenarios where a backup from longer ago would really help.
