If I use Mirror to incrementally backup a branch from C:\Program Files (for example) to D:\Program Files, where most of the source files already exist at the unlogged destination, then Mirror currently cannot proceed if Ztree determines that (total size of all source files) > (free space at destination), even if there ultimately is enough free space at the destination.

Anyone else think that it might be better to allow the user the option to proceed with the Mirror anyway, while keeping the warning?
