some ppl have already started working on this and there's been activity on the mailing list lately about this topic.

however it's a dangerous feature to add in (backup tools should never screw up their storage, and this feature goes and removes things) so a lot of care is needed.

the boring answer is: it's coming, and we need a lot of help for vetting patches and testing them out.

I think naming backups and archiving the old files should be separate applications - that could be generic to whatever backup tool you decide to use.
