I need to come up with a robust backup solution for 4 Macs, a lot of media and a large photo collection (stored separately). I recently bought 2 4Tb external hard drives and had planned doing as follows: - Using 1 of the drives as my main backup drives with 8 partitions: one time Machine backup drive for each Mac, and the 4 other partitions for other purposes. - On a regular basis (weekly?), I would clone the first external hard drive to the other using Carbon Copy Cloner (the drives are stored in separate locations). I have now discovered that Carbon Copy Cloner doesn't seem to handle cloning time machine backups smoothly so it might be easier to skip Time Machine altogether and instead simply backup from each of the Macks to the first HD using Carbon Copy Cloner (and then Clone to the other External HD separately) What do you think? Would there be a big disadvantage to skipping Time Machine?
