Nonstop backup cleanup fixed in TIH 2011?

I am currentlty using TIH 2010 with Win 7 64-bit. For some time I was using the NSB feature, which was working well; but I have had to discontinue using it because the only way I could "clean up" the backup storage was by manually deleting all backup archive files and starting over. Kind of defeats the purpose.

When I try to clean up the storage, I get a wait cursor for a few seconds, then it stops, but no backup archives are actually cleaned up.

The propblem with deleting old archives manually, is that the supporting file(s) that hold the metadata for the NSB are not updated.

Does anyone know if this issue has been resolved in TIH 2011? (or, even better, via an update/patch?)
