Re: Hot-backup.py won't create zipfiles bigger than 2GB

Since this question is about how to use Subversion, not how to
progress the development of the core project, you should at it on the
users_at_subversion.apache.org mailing list. (Plus, it appears you are
using VisualSVN, have you tried their support channels?)

Thanks,
