I have a question about how to set up my external drive for time machine backups of multiple computers. In the pre-time machine world, I partitioned my backup drive into multiple partitions and cloned my computers to their respective partitions. I know that Time Machine doesn't require a partition all to itself, and that all the data is just stored in a folder. Does that mean I can point Time Machine backups of 2 computers to the same partition and they each would backup happily? The advantage to not partitioning is that I don't have to reserve space in advance, so one computer can use more space than the other. Will backing up multiple computers to one partition work? Any disadvantages people have found?
