For example in a GNU/Linux VM
jumproot.vmdk
jumpswap.vmdk
jumpvari .vmdk
and then after you've done an initial backup snap of all the disks with vmbk.pl you can choose NOT to back up the swap area / disk / space in your hourly, daily, weekly backup cron jobs
You also get increased flexibility to resize it if you require without any impact to any other volumes or partitions
