I've recently re-jigged my system and upgraded to Snow Leopard. I've manually restored everything I want from a Time Machine back-up and am now back in business on my main drive. However, I now want to re-enable Time Machine but I'm having some problems; every time I back-up the total size is the same! I've excluded all the things I don't want, such as system-files, applications folder, developer folder, virtual machines folder, and a folder I use for large downloads (so they're not backing up at different stages). Every time though the total back-up size is calculated as the total data on my drive, minus the things I've excluded, and it crawls along at only a few kilobytes to a megabyte or so per-second! For a volume with just under a terabyte of data that's an awful long time. This doesn't seem right though, as it means that my back-up volume is just going to full up after a couple of back-ups are taken, which is unacceptable. Anyone know what can be done about this? Both the internal and external volume are Journaled HFS+, my only though really is that the back-up drive already has Time Machine files on it, indeed the biggest portion of my files (about 850gb) is already on the drive in the exact-same folder structure as I'm using now, so those files shouldn't even need to be backed up!
