RE: Resizing an existing repository while keeping the revision numbering

Does the local workspace able to check into the resized repository with the
dummy inserts with checking out?

I want to keep my repository in a "sizable size" for ease of backup and
holding about a 100 or less revisions at any 1 time is workable for me.
