Apple Mac OS X Time Machine Partition Tip

Apple's Mac OS X Leopard Time Machine will permit multiple computers to be backed up to one disk partition.  Its a better idea to allocate a partition for each system.  When the disk partition fills up, Time Machine starts deleting old backups to make room for new ones.  If there are two systems sharing the partition, one system's backup can get squeezed for room.  Its better to allocate a partition for each system, then Time Machine can use the entire partition.
