While the transfer is slow, the actual process of deciding what needs to be backed up is fast because OSX tracks which files have been added or modified. (I assume this is a feature of HFS+, but a quick google didn't turn up anything.) What this typically means is that the first time you run Time Machine it takes hours, but the hourly incremental backups that run after that generally only take a minute or two. In contrast a backup of an ext3 partition has to recursively look through the entire partition each time it runs. I use rdiff-backup to backup about 50 gb to an external usb drive and it takes about 40 minutes to do an incremental backup. Walt Attachment:
