Dun is a tool to backup files to remote (FTP, SFTP, WebDAV, .mac) or local storage devices. It is especially designed for Mac OS X Leopard. Backup and restore operations can be easily done directly from the menubar with a single click.
DRAFTECH Seems like a nice App, but did not work for me. Attempted to run a backup to a WebDAV network sharepoint, and it appeared to be working, plugging away for a few hours (large folder). When I checked on the backup after it was finished, all I had was a backup file of zero k. So, lots of time working, but with a net result of nothing... (Version 0.9.2)
if you find the time it would by nice if you could explain what kind of problems you are running into. Also the kind of webdav server that you are using might be of interest.
