[Box Backup] Clearing old files.

[Kai]

Is there any way as the administrator of a box backup server that I can
"compress" a users account. i.e tell it to go through and clear out old
files that have been supplanted or deleted?

I have a few accounts that are sitting at their hard limit and the actual
size of files on the clinet is about a third of what's on the backup server.


As I can't actually see the files there is no way I can compress the account
down to current files only is there?
